C, Spot compression views show that the finding represents a mass ( open arrows ) in the upper outer breast, adjacent to a normal-appearing lymph node ( closed arrows ). 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. The views are usually used for all routine screening clients. Stereotactic technique is much simpler and is used the vast majority of the time for these calcifications. Symptoms can include a lump, nipple discharge, skin or nipple retraction, or a change in the size or shape of the breast. How should the patient's arm on the side being examined be positioned for the CC projection? 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. 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. who are recalled for special views are determined to have carcinoma.

Masses: We will typically ask for spot compression views and ultrasound on any new mass or enlarging mass from prior mammograms. As a key element affecting mammography, proper positioning increases the sensitivity of the mammogram and augments the amount of breast tissue being imaged. If the lesion depth is far posterior (see Fig. compression views in the evaluation of asymmetries and architectural Adjust the patient to include all posterior and inferior breast tissue. When tomosynthesis images show a mass, the spot compression or spot magnification views which are otherwise commonly performed can often be skipped, and the woman can usually just have ultrasound(Fig. What does it take to outsmart cancer? 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. spiculation within tissue that appears unremarkable on 2D mammography.1. Magnification views
For every 1000 women screened, 2 to 7 will be found to have cancer on mammography(seeSummary of Cancer Detection Rates). In the TOSYMA trial, a randomized trial comparing tomosynthesis with synthetic mammography to standard 2D digital mammography alone in the German mammography screening program, a subanalysis explored performance by breast density category. results in better tissue separation and allows better visualization of the small area in
Pathology results yielded an infiltrating and in-situ carcinoma, with We can use this to our advantage for lesions seen only in the MLO view ( Fig. American Cancer Society medical information is copyrightedmaterial. Coldman A, Phillips N, Wilson C, et al.

In some cases, even if insurance is supposed to cover tomosynthesis, it may apply the charge to your deductible, or it may cover the mammogram but not the tomosynthesis. In current practice, the observed reduction in deaths from breast cancer among women participating in mammography is 40-60% [2, 3]. In this exam, an X-ray tube moves in an arc around the breast tissue, taking multiple images of the breast from different angles. A finding in this category has a very low (no more than 2%) chance of being cancer. Youll be asked to be still and hold your breath while the X-ray is done. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 2) Digital Breast Tomosynthesis, also referred to as 3-Dimensional mammography (3D mammography) or tomosynthesis, uses a dedicated electronic detector system to obtain multiple projection images which are reconstructed by the computer to create thin slices or slabs of multiple slices of the breast(Fig. Mammograms are 2-dimensional, taking two images of the breast: top to bottom and a side-to-side view from an angle. breast tissue "in the valley" between the two breasts. The location of a far lateral or far medial finding will be more affected by the obliquity on the MLO view than a more centrally located finding.

Patients feet should be facing forward toward the unit. Bahl M, Mercaldo S, Dang PA, McCarthy AM, Lowry KP, Lehman CD. These views are used in diagnostic breast workups in addition to the standard views. breast secondary to its tomosynthesis slice position. A large mass in the subareolar region of the left breast on the screening mammogram is almost surely a cyst. A mass that is in the anterior breast on the CC view will not correspond to a finding in the posterior breast on the MLO view as long as the nipple is relatively in profile. Ultrasound ( C) demonstrates a 1.4-cm corresponding solid mass with posterior shadowing (arrow) for which US-guided biopsy demonstrated a complex sclerosing lesion. Associated findings such as architectural distortion are often better seen than on the screening views.
