Abstract:

The objectives of this project are refinement and implementation of new methods designed to defeat the tradeoff between spatial resolution, temporal resolution and tissue coverage in dynamic gadolinium- enhanced MR mammography. The approach involves specialized software for data acquisition and reconstruction that allows dynamic scans of 32 sections through both breasts acquired at 10-13 second temporal resolution. Additional post-processing further improves temporal resolution to 5-6 seconds, and reduces motion artifacts for improved quantitation via in numerical fitting of temporal enhancement features of lesions. Objectives related to development of data acquisition and processing tools have been completed.
