| Purpose The purpose of this. Bahl M, Mercaldo S, Dang PA, McCarthy AM, Lowry KP, Lehman CD. Magnification views provide a clearer assessment The majority of the time there is no lesion and routine follow-up may be performed. The breast will flatten in the supine position used for US. This means the radiologist may have seen a possible abnormality, but it was not clear and you will need more tests, such as another mammogram with the use of spot compression (applying compression to a smaller area when doing the mammogram), magnified views, special mammogram views, and/or ultrasound. Philadelphia, Pa: Lippincott Williams & Wilkins; 2014. The downside of the MLO view is it is not 90 degrees to the cc view so localization of a lesion requires some thought.

Additional mammographic views and US should be used to evaluate the finding and establish the level of suspicion. 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. Conant EF, Zuckerman SP, McDonald ES, et al. Eight out of ten patients (80%) include magnification views or focal/spot compression views. If it moves medially or does not shift in position, then it is in the inferior or central breast. Osteras BH, Martinsen ACT, Gullien R, Skaane P. Digital Mammography versus Breast Tomosynthesis: Impact of Breast Density on Diagnostic Performance in Population-based Screening.

The spot compression views give us an idea of the borders of the lesion with smooth borders typically indicating benign lesions such as cysts and benign fibroadenomas (non-cancerous tumors), whereas irregular borders are more worrisome and may indicate a more aggressive lesion. Rest the patients arm with the elbow slightly bent across the top of the receptor. who are recalled for special views are determined to have carcinoma.

Conversely, an analysis of over 170,000 tomosynthesis exams compared to over 270,000 2D mammograms showed an increase in cancer detection of 1.6 per 1000 in women with heterogeneously dense breasts, but no improvement in cancer detection in extremely dense breasts [7]. True From the top looking down, the entire breast is depicted. 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.
