title: A comparison between whole body scans made at two hours and three hours after intravenous injection of Tc-99m HDP as to image quality and lesion detectability.
abstract: Bone scans of 35 patients were evaluated as to the quality and the number of bone lesions that could be detected at studies 2 hours and 3 hours after injection of Tc-99m HDP. It was found that 2 hour bone scans are of high "cosmetic" and diagnostic quality and that all lesions present at 3 hour scans are well visualized at 2 hours. These features are among the major advantages of the use of Tc-99m HDP over other diphosphonates.
