Increased signal intensity of T1-weighted MR image of physiologic intracranial calcifications.
Among 1500 MR studies of the brain, performed during 1 year, there were six cases of physiologic calcifications (four in the falx cerebri, two in the deep gray matter) that revealed high signal intensity on T1- and variable signal on T2-weighted images. This phenomenon should be recognized and not confused with entities of clinical significance especially hemorrhage.
