The mediolateral oblique (MLO) view is one of the two standard mammographic views, alongside the craniocaudal (CC) view. The greatest benefits for improved cancer detection and recall reduction from tomosynthesis are for the baseline (first) screening examination, with benefit on subsequent exams varying by density and age but sustained over multiple years [4, 5, 18, 19].

Architectural distortion: A very common occurrence but a potential sign for a true lesion. Additional views with slightly different projections and particularly spot compression views are utilized for evaluation of this abnormality. 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. Stepped oblique views are similar in concept; full images are obtained at 10- to 15-degree intervals between the CC and MLO views. Vascular calcifications in the arteries of the breasts may also present as microcalcifications. Additional mammographic views might include spot compression, spot compression with magnification, tangential views, or other special views. Add an XCCL if you are not able to visualize all the lateral glandular tissue on the CC. Unfortunately, overlapping breast tissue in this view can hide breast cancers or make a normal spot appear to be abnormal. 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. Occasionally, MRI is useful to localize a suspicious mammographic finding seen in one view that is not amenable to US or stereotactic biopsy. 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. 4-3 , red, green, and most orange dots), then it is either due to superimposition of breast tissue or obscured on the other projection. Additional mammographic views and US should be used to evaluate the finding and establish the level of suspicion. 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. Multiple views and other techniques like spot compression will tend to give a better picture of equivocal findings. distortion. Some areas that look unusual on the standard Rolled CC views? Then look at that depth on the other projection, which should be similar between views as long as the nipple is in profile ( Fig. Adjust the patient to include all posterior and inferior breast tissue.
