Susceptibility Weighted Imaging (SWI) shows exquisite structural details with unprecedented resolution. This technique is of significant interest for breast imaging, especially in detecting micro-calcification. Calcification, an early indicator of ductal carcinoma in situ, an invasive form of breast cancer, is not clearly visible on either conventional MR images or X-ray mammography of dense breast tissue. Here we show how optimized SWI detects calcification with an over estimation of lesion volume by a factor of 2, yet with better contrast than CT.
