How many views are obtained for a routine mammogram?
Four views are obtained for a routine mammogram. Mediolateral oblique (MLO) and craniocaudal (CC) views of each breast are obtained. In some patients, more than four images may be needed to visualize all of the breast parenchyma adequately.
Which view visualizes the most breast tissue?
MLO view visualizes the most breast tissue.
Which portion of the breast is better visualized on the CC view than on the MLO view?
The medial breast is better visualized on the CC view.
What if there are comparison studies elsewhere? Do we need to get them?
If the mammogram is negative, no. Research has shown that it is not cost-effective and does not improve patient care to obtain comparison studies for examinations that are normal. If there is an abnormal finding, an attempt should be made to get the prior studies from the outside institution. If they cannot be obtained, the patient should be recalled for additional evaluation.
