Both cerebral hemorrhages and calcifications may show similar internal heterogeneity on phase images, limiting its clinical utility. We assessed a dipole artifact (both the upper/lower poles and the equatorial region) on phase images in 123 patients with hemorrhages (n=119) and calcifications (n=75). All hemorrhagic lesions were perfectly determined, while all but one calcification showed a diamagnetic dipole pattern. The equatorial phase values (degree) were significantly different between hemorrhages and calcifications (-10.41±10.66 versus 10.86±9.53; P<0.0001). The signal intensities of both the lobes and the equatorial rim on GRE phase images accurately differentiate hemorrhages from calcifications irrespective of internal heterogeneity.
