October 18, 2000 8:30-8:45. Problem Solving with FDG Positron Emission Mammography.

Purpose: To examine one potential clinical application of dedicated devices for positron emission mammography.Background: Dedicated devices for breast imaging with FDG have technical specifications that appear well-suited for detecting small breast cancers, including registration with x-rays, high count sensitivity, and spatial resolution in the 2-3 mm range.Methods: In IRB-approved clinical trials, patients who were scheduled for biopsy for suspicious findings on x-ray mammograms were injected with 10-20 mCi FDG intravenously one to two hours prior to x-ray guided core biopsy or lumpectomy.
