Technique for Improving Quality of Bone Scans

Abstract

A technique that has significantly enhanced the quality of bone scan images in our institution is described. The increased quality has been accomplished by the introduction of two modifications of present bone-scanning techniques: (A) adjusting the focal plane of the lower probe of the dual-probe scanner to coincide more closely with the midaxillary plane of the thoracic spine to minimize the background arising from the soft tissue of the trunk; and (B) reducing the spinal curvature to improve the resolution of the spine and ribs. The latter modification also helps eliminate high lumbar activity sometimes seen on the anterior scan.
