"Not all 4 views are always performed in all mammogram studies. For instance, in clients under 40 only 2 MLO views may be done to limit radiation exposure, depending on local policy and the discretion of the radiologist."

"As a general rule, parenchymal asymmetries are worked up with straight lateral (SL) and rolled CC (rolled) views. Calcifications are worked up with magnification views (mag views). The degree of roll does not have to be very significant in most cases. All you are trying to achieve with SL and rolled views is to separate summation shadows from each other. Very often a summation shadow seen on an MLO view will disappear if the very same view is immediately performed."

"When to use which view "
"There are numerous mammography views that can broadly be split into two groups"
"The reason is that a mammogram is a two dimensional representation of a 3 dimensional structure; by the same token a map is not an accurate representation of the earth's actual geography. The ML view loses significant tissue volume in the upper outer quadrant of the breast where statistically the most breast cancers are found. By doing an MLO view you get extra tissue without extra exposure. The downside of the MLO view is it is not 90 degrees to the cc view so localisation of a lesion requires some thought. The two views are not orthogonal."
