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.
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.
