Novel MRI Technique Could Reduce Breast Biopsies, University of Washington Study

Water diffusion measurements with MRI could decrease false-positive breast cancer results and reduce preventable biopsies, according to a new study published online in the journal Radiology. Researchers said the technique also could improve patient management by differentiating high-risk lesions requiring additional workup from other non-malignant subtypes. Dynamic contrast-enhanced MRI (DCE-MRI) has emerged in recent years as a useful tool in breast cancer detection and staging. One of its primary limitations is a substantial number of false-positive findings that require biopsies.
