Baseline screening mammography with one versus two views.

Two-view baseline screening mammograms (oblique and cranial views) of 303 women recalled for further studies from among 7,245 women screened were reviewed by four experienced radiologists separately to evaluate the importance of the number of views taken for screening. As compared with the oblique view only, two views, increased the number of cancers detected and decreased the number of false-positive cancer diagnoses of two radiologists, but increased that of the other two.
