FIG 1. A, Coronal and B, axial brain MR images in a spontaneously aborted 22-week fetus. The image quality was assessed as excellent and findings reported as normal, which agreed with the autopsy report. The dark structures (arrows) in the immediate periventricular regions are the germinal matrices. Migrating neurons are shown in cerebral hemispheres as gray matter signal intensity against the high signal intensity of the white matter.
