The Anger longitudinal emission multiplane tomoscanner and a 15-in. Anger camera with multipeak spectroscopic capability were compared in a series of 51 patients. The tomoscanner was preferred in 49%, the camera in 12%, and 39% were equivalent. The tomoscanner preference is statistically significant (p less than .025). These data support the conclusion that the Anger multiplane tomographic scanner is the instrument of choice for gallium-67 imaging.
