Mediolateral view

Dr Jeremy Jones and Stefano Pacifici et al.

The mediolateral (ML) view is a supplementary mammographic view and shows less breast tissue and pectoral muscle than the mediolateral oblique view (MLO view).

A lateral projection is performed as an additional view in order to localize the exact position of a lesion that has been seen on standard views. The lateral view is also performed whenever it is necessary to take a perpendicular image to cranial-caudal (CC) view for pre-surgical lesion localization.

An optimal mediolateral view should demonstrate the pectoral muscle, inframammary angle and nipple in profile and display the majority of breast tissue.
