The presence of calcium deposits in the breast can be an indicator of malignancy, so the ability to detect such abnormalities by MRI would be significant. Calcium deposits have a different magnetic susceptibility from surrounding tissues that can in principle be observed using susceptibility weighted imaging (SWI). Here we introduce a technique to locate a susceptibility induced signature within a data set by computing the cross-correlation between a template and the target image.
