For rolled CC views, the breast is placed on the image receptor and the superior breast is rolled lateral (CCRL) or medial (CCRM). distortion. Note that the yellow dot may not be viewed on the CC view because of the far posterior location. Stepped oblique views are similar in concept; full images are obtained at 10- to 15-degree intervals between the CC and MLO views. These are similar in concept to shallow oblique views. Breast imaging for cancer screening: Mammography and ultrasonography. (1999) ISBN: 0071353984, 3. The majority of findings identified at screening will be determined to represent superimposition of normal breast tissue (summation artifact). Beyond the CC and MLO Views - Advanced Health Education Center Talk to your doctor about your mammogram results and what you need to do next. Please check with a physician regarding your specific condition, if you have any questions, or need a diagnosis. An annual mammogram is a screening 1. Cranialcaudal, sometimes also referred to as Cranial Caudal or CC, is a view of the breast taken directly from above. Spot views apply the compression to a smaller area of tissue using a small compression plate or cone. This makes communicating about the test results and following up after the tests easier. Rafferty EA, Durand MA, Conant EF, et al. (CC view slice 43/55, MLO view slice 14/50) 8. 2). Disclaimer: The contents of this article, including text and images, are for informational purposes only and do not constitute a medical service. us to detect a small, early stage carcinoma in this patient with dense We have to mentally account for the differences in obliquity between the MLO and a true lateral view ( Fig. A 74-year-old female presented for routine screening mammography. Spot compression views are the most common additional views obtained in our practice. 9. Imaginis does not endorse and has no responsibility for the content of any other sites listed on Imaginis.com, and provides links and references merely as a convenience to its users. For this reason, this category is often divided further: 4A: Finding with a low likelihood of being cancer (more than 2% but no more than 10%), 4B: Finding with a moderate likelihood of being cancer (more than 10% but no more than 50%), 4C: Finding with a high likelihood of being cancer (more than 50% but less than 95%), but not as high as Category 5, Highly suggestive of malignancy Appropriate action should be taken. As in spot compression views, an additional 20% of cancers will be detected when US is used appropriately as a part of the diagnostic evaluation. She has used hormone Its a screening test used to look for potential tumors. There are a few things to keep in mind when localizing a finding. were able to localize this finding to the 3 oclock position in the diagnostic imaging should be obtained with DM spot-compression magnification views for complete evaluation. Br J Radiol. Breast Cancer Res 2017; 19:67, 14. Together, were making a difference and you can, too. A spot view(also known as a spot compression view or focal compression view) is an additional mammographic view performed by applying the compression to a smaller area of tissue using a small compression paddle, increasing the effective pressure on that spot. Using the information available from the mammogram, it is often possible to have a good idea of the location and US appearance of a finding before you scan. A diagnostic mammogram is monitored by the radiologist at the time of the examination. That is, unless there is a contraindication, screening mammograms consist of these 4 views. (2008) ISBN: 0071548351, 5. Note that all mammograms are done with some breast compression, but a spot compression test uses a special plate or cone which lets you see a clearer image of a much smaller area. 4-2 ). Using volumetric breast density to quantify the potential masking risk of mammographic density. This may also suggest that the radiologist wants to compare your new mammogram with older ones to see if there have been changes in the area over time. The measurements should be within 1 cm, with the larger measurement on the MLO. When one breast is All rights reserved. Stereotactic technique is much simpler and is used the vast majority of the time for these calcifications. Symptoms can be due to breast cancer, but are more often due to benign (noncancerous) conditions. Is it real, or is it cubic zirconium? views are often used to evaluate micro-calcifications, tiny specks of calcium in the We will give you tools to localize lesions in two orthogonal projections. AJR Am J Roentgenol 2017; 208:222-227, 15. include magnification views or focal/spot compression views. About 95% of areas resulting in call back prove to be normal overlapping tissue or benign changes such as cysts. She Adiagnosticmammogram is used to check for breast cancer when there is a sign or symptom of disease, or to evaluate an abnormality seen on a screening mammogram. If you are experiencing an urgent medical condition, call your local emergency services [e.g., 9-1-1 (in the USA) or 1-1-2 (in Europe)]. compression views in the evaluation of asymmetries and architectural Information found within the Imaginis.com website or in other sites linked to from Imaginis.com is provided for educational purposes only and is not intended to be used as a substitute for diagnosis and treatment by a medical doctor. As all radiologists who read mammograms know, breast tissue has an Detection of breast cancer with addition of annual screening ultrasound or a single screening MRI to mammography in women with elevated breast cancer risk. For calcifications: compression magnification views in TL 90 and CC Standard Projections: MLO and CC Mammograms are displayed in conventional manner paired (to permit bilateral comparison) MLO followed by CC with patients right breast on the left side of the screen and left breast on the right side of the screen. The downside of the MLO view is it is not 90 degrees to the cc view so localization of a lesion requires some thought. 8. area of breast tissue easier to evaluate. breast tissue "in the valley" between the two breasts. The two views are not orthogonal. It is the most important projection as it allows depiction of most breast tissue. D and E, US shows an irregular hypoechoic mass ( open arrows ) adjacent to the node ( arrow ). Spot compression views are often uncomfortable, but when there is a large cyst present they can be downright painful. 2005 - 2023 WebMD LLC. Save my name, email, and website in this browser for the next time I comment. particularly in dense breasts,has been a longstanding challenge. Does asymmetry on mammogram mean cancer? Many centers have the computer software needed to create a synthetic 2D mammogram from the same images used to create the tomosynthesis slices. A large mass in the subareolar region of the left breast on the screening mammogram is almost surely a cyst. From mammograms to living after treatment. Berg WA, Zhang Z, Lehrer D, et al. Repeat Screening Outcomes with Digital Breast Tomosynthesis Plus Synthetic Mammography for Breast Cancer Detection: Results from the Prospective Verona Pilot Study. This is the portion of Research shows that tomosynthesis combined with a mammogram detects about one more cancer per 1,000 women screened. We do not use these often because other techniques can usually determine the location with fewer exposures. of early malignant changes within normal fibroglandular tissue, (Having dense breasts also slightly raises your risk of getting breast cancer.). Adjust the height of the receptor to place the top at the level of the sternoclavicular joint or halfway between the top of the shoulder and the axillary crease. The images are reconstructed as multiple thin slices which can be individually scrolled through to reduce tissue overlap, like flipping through the pages of a book(Figs. abnormalities usually appear more prominently and the margins (borders) of the abnormality Your breasts look the same (they are symmetrical) with no masses (lumps), distorted structures, or suspicious calcifications. Irregular sharp and/or serpiginous microcalcifications, particularly if they are numerous and tightly grouped, generally require a biopsy which may be performed with stereotactic technique and local anesthesia or may be performed with open technique with needle localization for the surgeon who then completely removes the microcalcifications for pathologic evaluation. This synthetic mammogram can be used instead of the standard 2D mammogram so that the radiation dose from tomosynthesis is similar to a standard mammogram. You may check that there is comparable breast tissue visualized by comparing the PNL measurements on the CC and the MLO. What Does a Mammography Technologist Do? Using 2 hands, pull the patients breast up and away from the chest wall onto the receptor. When normal tissue undergoes spot compression, it will spread out and become less dense; the normal, respectful breast architecture becomes more apparent. We have several views to help us. this density (if possible). CME/CE, Dense Breasts and Supplemental Screening, Table: Cancer Detection by Screening Method, Mammography, 3D Mammography (Tomosynthesis), Federal Insurance Bill: Find It Early Act, Preguntas y respuestas de los pacientes/Patient Questions and Answers, Lista de riesgos de cancer de mama/Breast Cancer Risk Checklist, Hoja informativa para pacientes/Patient Fact Sheet. Youll find self-guided, study-by-mail mammography courses that you can learn at your own pace and in the comfort of your home. (Note: These same BI-RADS categories can also be used to describe the results of a breast ultrasound or breast MRI exam. 7. 4-8 ). Each of the colored dots on the CC view can only represent the same color dots on the MLO view and vice versa. Magnetic resonance imaging (MRI)? What happens when one breast is left out of the compression field? It looks kind of ugly on the screening views. A mass seen in the lateral breast (. Unfortunately, overlapping breast tissue in this view can hide breast cancers or make a normal spot appear to be abnormal. can be very helpful in both localizing the lesion and assessing the level of suspicion. 4-3 ). Breast pain, in particular, is very rarely due to cancer unless there is also a lump (and tender lumps are much more often benign than cancerous). The best guess spot compression, true lateral, or stepped oblique views can help whether the finding is best seen in the CC or MLO view. breasts. CC and MLO spot-compression views demonstrated no definite abnormality in this area (Figure 3), but a targeted ultrasound revealed a 5.5-mm spiculated mass at the 3 o'clock position (Figure 4). If you are uncertain whether the US and mammographic findings are the same lesion, but the US and mammographic findings individually are both suspicious enough to warrant biopsy, there is no real need to prove that they correspond before performing a biopsy. Many noncancerous (benign) conditions can also produce masses and calcifications and even normal tissue can appear as areas of asymmetry. Multiple views and other techniques like spot compression will tend to give a better picture of equivocal findings. Think before you speak. mammogram and usually involves taking images (views) of each breast from two different Radiology 2020; 295:285-293, 5. 4-6 ). Normal: Abnormal breast masses will not compress out but imaging artifact will. A spot view (also known as a spot compression view or focal compression view) is an additional mammographic view performed by applying the compression to a smaller area of tissue using a small compression paddle, increasing the effective pressure on that spot. This can also be used to describe changes from a prior procedure (such as a biopsy) in the breast. The nipple is not in profile on the CC view, making distance from the nipple considerably different on the MLO view. patient to come back for additional imaging (on the same day or on a subsequent date). Standard 2D mammography has been shown to miss about 40% of cancers present in women with extremely dense breasts and 25% of cancers present in women with heterogeneously dense breasts [12-17]. You consent to our use of Cookies by continuing to access our site. Additional diagnostic spot compression views in the CC and MLO projections ( B) demonstrate persistence of the AD finding (circles). the most medial (central) portions of the breasts. Should I just let her go? Over 95% of the BI-RADS 0 mammograms turn out to be benign. at the 3 oclock position (Figure 4). We can use this to our advantage for lesions seen only in the MLO view ( Fig. With these categories, doctors can describe what they find on a mammogram using the same words and terms. Imaginis is a registered service mark of Imaginis Corporation, a health services company. All mammograms involve compression of the breast. | Purpose The purpose of this. Findings seen in one view only on conventional 2015 - 2023, DenseBreast-info, Inc. ALL RIGHTS RESERVED | 501(c)(3) Public Charity. 5). Stage T1c, N0, M0 stage 1 left breast cancer. The radiologist is concerned enough to recommend a biopsy. that get recalled for additional views are subsequently categorized as "benign" or "probably benign" and receive follow up Spot compression views may be performed with or without magnification (spot mags). Digital Adequacy A needle biopsy is usually recommended when there is even a low (> 2%) level of suspicion for cancer. If the US did not show a simple cyst, spot compression views can still be performed after the US if needed. A spot compressed MLO view demonstrates dispersion of the area of possible spiculation. Mandelson MT, Oestreicher N, Porter PL, et al. In women with extremely dense breasts, studies have shown mixed results as to whether tomosynthesis improves cancer detection over standard 2D mammography [7-10]. Compression reduces the amount of radiation needed to penetrate the tissue and also spreads out the breast tissue to help produce clearer images. A cancer masked on a 2D mammogram can still be masked on tomosynthesis unless the cancer is at least partially surrounded by fatty tissue. for additional or special views should not be alarmed. Margins also become clearer using spot compression. If the radiologist or physician interpreting the screening mammogram images sees something that is questionable,. Ellen Shaw De Paredes. Breast tomosynthesis enabled Lets say that your colleague identified a suspicious one-view asymmetry on screening and now you are seeing her for diagnostic evaluation. Our first step is to determine lesion depth (see Fig. BARBARA APGAR, M.D., M.S. Tomosynthesis takes multiple pictures from several angles: 11 images. Associated findings such as architectural distortion are often better seen than on the screening views. What is CC and MLO views . Renew or update your current subscription to Applied Radiology. 10. How is spot compression used in a mammography? JAMA Netw Open. Special mammography views, which may include magnification views or focal/spot compression views. This is a good place to start for a one-view finding that may be obscured in the other projection. Cysts typically do not require any further follow-up unless they are painful or they may be aspirated under ultrasound guidance. At the American Cancer Society, we have a vision to end cancer as we know it, for everyone. Spot compression views are often helpful in deciding whether a finding represents summation artifact or a true lesion. While tomosynthesis improves breast cancer detection in women with fatty, scattered fibroglandular density, and heterogeneously dense breasts, studies have shown mixed results in women with extremely dense breasts. Sometimes additional images are needed to fully include all the breast tissue. Architectural distortion: A very common occurrence but a potential sign for a true lesion. tomosynthesis slice number. Then look at that depth on the other projection, which should be similar between views as long as the nipple is in profile ( Fig. Tomosynthesis Images. Occasionally, MRI is useful to localize a suspicious mammographic finding seen in one view that is not amenable to US or stereotactic biopsy. BI-RADS classifies breast density into 4 groups, which are described in Breast Density and Your Mammogram Report. Final Thoughts There are two basic procedures in mammography: the Cranial-Caudal (CC) and the Mediolateral-Oblique (MLO). A professional. Diagnostic mammography starts with the same images as a screening mammogram and may also include additional images taken to evaluate an area of concern. only a specific area of the breast, the effective pressure is increased on that spot. On the web since 1997. This is a normal test result. As of 2017, there. 4-4 ). Go ahead and skip the spot compression views when the mass for which the patient is being recalled is very likely to represent a cyst ( Fig. Breast cancer screening using tomosynthesis and digital mammography in dense and nondense breasts. and 6), followed by whole breast radiation therapy. WebMD does not provide medical advice, diagnosis or treatment. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 1-2). Rest the patients arm with the elbow slightly bent across the top of the receptor. Then make your best guess about where the finding may be located in the other projection. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. The Women's Health Resource. In women with extremely dense breasts, an additional 5.8 invasive cancers per 1000 were detected using tomosynthesis plus synthetic mammography than by use of standard mammography [8.1 per 1000 (32/3940) vs. 2.3 per 1000 (6/2629), OR 3.8 (95% CI: 1.5, 11.1)] [6]. Add an XCCL if you are not able to visualize all the lateral glandular tissue on the CC. In pregnant women, imaging is usually done only for diagnostic purposes, when symptoms are present, and ultrasound is usually the first imaging test performed. mammogram revealed an area of architectural distortion in the lateral In some cases, though, either shallow or stepped oblique views can localize a finding when our other tricks havent helped. Even when the location on the CC and MLO views is obvious, well need to remember that the MLO cannot be treated like a true lateral view when determining the location of a lesion. Vascular calcifications in the arteries of the breasts may also present as microcalcifications. BI-RADS 1 is negative; BI-RADS 2 is benign; BI-RADS 3 is probably benign; BI-RADS 4 is suspicious; BI-RADS 5 is highly suspicious; and BI-RADS 0 is incomplete, requiring additional imaging including additional views, with or without spot compression, spot magnification views (typically for microcalcifications), and ultrasound. There are two basic procedures in mammography: the Cranial-Caudal (CC) and the Mediolateral-Oblique (MLO). Am Fam Physician. (2010) ISBN: 9781605470313, 6. 4-10 ). Ultrasound ( C) demonstrates a 1.4-cm corresponding solid mass with posterior shadowing (arrow) for which US-guided biopsy demonstrated a complex sclerosing lesion. can be better seen on compression views. and her mammogram last year was interpreted as normal. To do this accurately, well use the depth of the finding (distance from the nipple). Peart, O. J.. Lange Q & A. In addition to the oclock position and depth of a lesion, it can be helpful to consider the location of a lesion relative to the central core of fibroglandular tissue. If a persistent abnormality is seen, we will commonly ask for an ultrasound to exclude an underlying lesion in the breast. 2019;92(1093):20180101. Additional mammographic views and US should be used to evaluate the finding and establish the level of suspicion. When a 2D mammogram and tomosynthesis are performed together (in combination mode), the study results in about twice the radiation dose to the breast as from a 2D mammogram alone and the dose is greater in thicker breasts. The true location of a lesion will be superior or inferior to its apparent location on the MLO view, depending upon whether it is located in the medial or lateral breast, respectively. The breast is placed on the surface (detector) of the mammography system and is briefly squeezed (compressed) between two paddles for a few seconds while an x-ray is taken. Global Asymmetry, Focal Asymmetry, Developing Asymmetry From the top looking down, the entire breast is depicted.

RadComm helps mammographers live their best life by providing quality, specialized, post-secondary course work, while helping others. This can cut down on anxiety in people who may have to repeat tests if the radiologistthinks theyve spotted a possible cancer, and it also means fewer follow-up tests are needed.
