An improved means of detecting upper abdominal abscesses using the dual radionuclide subtraction technique was applied to 51 patients. 67Gallium citrate was used in the localization of the lesion and 99Tc-labeled human albumin microspheres and 99Tc sulfur colloid were used for subtracting out the interfering background from normal organ concentrations. The procedure provided the parameter capabilities for localization of the abscesses as well as information on their shape and size. Compared to nonsubtraction Ga procedures, 53% more abscesses were diagnosed using the subtraction technique.
一种使用双放射性核素减法技术检测上腹部脓肿的改进方法应用于51例患者。柠檬酸镓67用于病变定位，99锝标记的人白蛋白微球和99锝硫胶体用于减去正常器官浓度产生的干扰背景。该程序提供了脓肿定位的参数能力以及有关其形状和大小的信息。与非减法镓程序相比，使用减法技术诊断出的脓肿多53%。
