A cadaver's vertebral column, a phantom, and a volunteer were imaged on a 1.5-T MR scanner to study the thin, uniform, dark, transverse lines that characterize some intervertebral disks. An artifactual dark line appears when the field of view (FOV) and matrix steps (n) are chosen so that d = FOV/n, where d equals the intervertebral disk height, or spacing between phantom vertebrae. The artifact...
