Computer-aided detection (CAD) for breast MRI may improve standardization and the analysis of benign and malignant lesions.
A group from the Seattle Cancer Care Alliance and the University of Washington Medical Center, led by Dr. Teresa Williams, conducted a retrospective examination of 154 breast lesions deemed suspicious by radiologists that were only visible on MRI and that had been biopsied under MRI guidance.
The group used version 3.0 of the CADstream software from Confirma of Kirkland, WA, to analyze the breast tissue and mark areas where MRI data curves were characteristic of abnormal lesions.
Analysis of the tissue enhancement data, as displayed in the CAD-processed images, identified 38 of the 41 malignant lesions examined by radiologists using the software. The radiologists also noticed a reduction in the false-positive rate.
The study is scheduled for publication in the July issue of the journal Radiology.
