Tomosynthesis helps characterize lesion margins and may increase diagnostic accuracy for noncalcified masses, distortions, & asymmetries. Lesions may appear to resolve on conventional spot compression views, but can be identified as true lesions on tomosynthesis. Tomosynthesis can define the accurate location of lesions seen on only a single conventional mammographic view. In some cases, tomosynthesis may obviate the need for multiple mammographic images obtained during conventional diagnostic work-up and result in radiation dose-reduction. Diagnostic tomosynthesis may resolve pseudolesions on BIRADS-0 screening callbacks & obviate the need for sonography in some cases.

Review basic principles of digital breast tomosynthesis Case-based presentation to illustrate the use of tomosynthesis in the diagnostic setting.  Case examples will include: Tomosynthesis used for diagnostic workup of BIRADS 0 screen callback cases, particularly for architectural distortions, noncalcified masses, & focal asymmetries. Lesions visualized on tomosynthesis, but occult or less conspicuous on conventional spot compression. Imaging features of these lesions will be reviewed, & pathologic correlation will be included. Lesions seen in a single mammographic view, but accurately localized by tomosynthesis.
