Initial Result of a Prospective Study: Comparison between a Low Dose 3D Stereo Mammography and FFDM

摘要

This report describes the initial result of a prospective clinical trial to compare 3D stereoscopic mammography (3DSDM) and standard full-field digital mammography (FFDM) for detection of biopsy proven cancers in a diagnostic population. In 3DSDM exam, an additional low-dose image is taken from 4 degree right after taking standard FFDM images in left/right CC and MLO. A total of 2,016 patients underwent 3DSDM exams since February, 2011 through March, 2012, which were read by different radiologists independently. Compared to FFDM, 3DSDM significantly reduced false positive detection by 29.4% (p=0.007). Cancer detection was slightly improved by 3D 4% although there was no statistical significance (p=0.317).
