HMS Instructor of Radiology Phoebe Freer (above) explains the benefits of tomosynthesis, an imaging tool developed at Massachusetts General Hospital to enhance breast cancer screening. During a tomosynthesis exam, a camera moves in an arc over the patient, taking a series of low-dose images, which get stitched together by software. Radiologists use the resulting 3D compilation to find tumors that might be hiding and scrutinize potential problem areas before worrying patients.

This podcast also explores 3D tissue models developed in the Brugge laboratory to study cancer. Plus, Professor of Radiology Tina Young Poussaint at Children's Hospital Boston shares her perspective.
