What is a Cleavage View?
A cleavage view (also called “valley view”) is a mammogram view that images the most medial (central) portions of the breasts. This is the portion of breast tissue “in the valley” between the two breasts. When one breast is imaged and the other breast is left out of the compression field, some of the breast being imaged may get pulled or left out too. To get as much medial tissue as possible, the mammogram technologist will place both breasts on the plate at the same time to image the medial half of both breasts.
