It is the most important projection as it allows depiction of most breast tissue. A mammogram might reveal that the breasts have different densities.

Many noncancerous (benign) conditions can also produce masses and calcifications and even normal tissue can appear as areas of asymmetry. The advantage of using magnification with spot compression is the ability to see fine architecture and calcifications well, although the disadvantage is lower contrast. What next? Spot magnification views are performed to determine the number and shape of the microcalcifications. Suspicious abnormality Biopsy should be considered. This system also organizes assessments and explains the importance of the findings. When a cancer undergoes focal (spot) compression, the abnormal tissue will typically appear more dense than the surrounding tissues, and mass borders are more clearly seen. Our routine imaging for an abnormal screening mammogram includes a true lateral view (mediolateral [ML] or lateromedial [LM]) and spot compression views of the finding ( Fig. This system (called the Breast Imaging Reporting and Data System or BI-RADS) sorts the results into categories numbered 0 through 6. We reviewed earlier how a lateral lesion shifts lower from the MLO to the ML view and a medial lesion shifts up (see Fig. Five Consecutive Years of Screening with Digital Breast Tomosynthesis: Outcomes by Screening Year and Round.

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.

For patients with a protruding abdomen, you may have to add a 90-degree lateral view focusing on inferior breast tissue and an open IMF. Screening mammograms have been performed since the 1970s. In addition to your free gift, youll get tons of useful information on industry news, mammography resources, and exclusive offers on RadComm courses only available to our subscribers. tissue without focal masses or asymmetries and without changes when You may check that there is comparable breast tissue visualized by comparing the PNL measurements on the CC and the MLO.

Ask yourself whether the lesion is at the border of the fibroglandular tissue, more centrally within this tissue, or in the retroglandular fat. Cranialcaudal, sometimes also referred to as Cranial Caudal or CC, is a view of the breast taken directly from above. position to prevent drooping (camel nose appearance). Instruct the patient to stop breathing during the exposure. Doctors use a standard system to describe mammogram findings and results. Written by Richard Oria, M.D. As a key element affecting mammography, proper positioning increases the sensitivity of the mammogram and augments the amount of breast tissue being imaged. The two views are not orthogonal. 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]. The detection If the lesion is medial, then the LM view is preferred. J Natl Cancer Inst 2014; 106, 3. Custom boutique photography for newborns, children, families, seniors, and weddings This makes communicating about the test results and following up after the tests easier. mammography images are often shown to be normal tissue on the spot views. Cancer Information, Answers, and Hope. Procedures and Documentation for Advanced Imaging: Mammography & Quality Management. This is a dictionary that radiologists use to describe findings in a breast imaging report. question. Our team of experts compiled these comprehensive tips in performing the proper positioning for CC and MLO to help you get proper CC and MLO views. Note that the yellow dot may not be viewed on the CC view because of the far posterior location. 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 we are not sure whether the finding is medial or lateral, then an ML is performed because statistically, most cancers are located in the lateral breast. with mammography in 12 months or 6 months, respectively. The goals of the workup are to decide whether the finding represents a true lesion and, if so, to localize it in two orthogonal projections, and determine its level of suspicion. Tax ID Number: 13-1788491. directions. In current practice, the observed reduction in deaths from breast cancer among women participating in mammography is 40-60% [2, 3]. aspect of the left breast, seen on the CC tomosynthesis view only The mediolateral oblique (MLO) view is one of the two standard mammographic views, alongside the craniocaudal (CC) view. Mammographic screening is the recommended first step in breast cancer screening for all women aged 40 years and older, except those who are pregnant. The measurements should be within 1 cm, with the larger measurement on the MLO. 5). Additional diagnostic spot compression views in the CC and MLO projections ( B) demonstrate persistence of the AD finding (circles). For a finding seen in both CC and MLO views, we need to remember that an MLO view is typically obtained at a 30- to 60-degree angle, although a true lateral view is obtained at 90 degrees. Spot compression is 4-3 , red, green, and most orange dots), then it is either due to superimposition of breast tissue or obscured on the other projection. The craniocaudal view (CC view), along with the MLO view, is one of the two standard projections in a screening mammography. distortion. mammographically-guided needle localization and a lumpectomy (Figures 5 We are viewing a 3-dimensional object in 2 dimensions. All rights reserved. 2019;92(1093):20180101. If a lesion is seen only on the CC view, the location in the superior or inferior breast must be determined. Radiologists use additional mammographic views, such as magnification or spot compression views, or ultrasound to help distinguish benign from cancerous changes. 7. Spot compression is also known as compression mammogram, spot view, cone views, or focal compression views.
