To assess the radiosulfur colloid distribution in the liver-spleen scans of trauma patients, 73 trauma patients (age: 4-74 years, mean: 32 years) who had Tc-99m sulfur colloid liver-spleen scans for trauma workup were studied and compared with the liver-spleen scans of 87 control patients (age: 2-64 years, mean: 36 years). Radiocolloid distribution was visually assessed by two physicians independently, and the areas of the greatest density in the liver and spleen on the posterior view that included both organs were compared. The scans were grouped into three grades: Grade I, liver density greater than spleen density; Grade II, both organs showing equal density; and Grade III, splenic density greater than liver density (colloid shift). Forty-three of the trauma patients (59%) were in Grade III, 22 (30%) in Grade I, and 2 (11%) in Grade II. The control group had 12 (14%) patients in Grade III, 54 (62%) in Grade I, and 21 (24%) in Grade II. When the young adults and children of the trauma patients (age: 4-20 years, mean: 14 years) were looked at separately, 17 of 20 (85%) showed colloid shift (Grade III). It is concluded that there is a significantly higher incidence of colloid shift in trauma patients compared to control patients (P less than .01).
为评估创伤患者肝脾扫描中放射性硫胶体的分布情况，我们对73例因创伤检查而行锝-99m硫胶体肝脾扫描的创伤患者（年龄4至74岁，平均32岁）进行了研究，并与87例对照患者（年龄2至64岁，平均36岁）的肝脾扫描结果进行比较。由两名医生独立对放射性胶体分布进行视觉评估，并比较后位视图中包括肝脏和脾脏在内的肝脏和脾脏最大密度区域。扫描结果分为三个等级：I级，肝脏密度大于脾脏密度；II级，两个器官密度相等；III级，脾脏密度大于肝脏密度（胶体移位）。73例创伤患者中，43例（59%）为III级，22例（30%）为I级，2例（11%）为II级。对照组中，12例（14%）为III级，54例（62%）为I级，21例（24%）为II级。当单独观察创伤患者中的年轻人和儿童（年龄4至20岁，平均14岁）时，20例中有17例（85%）出现胶体移位（III级）。结论是，与对照患者相比，创伤患者中胶体移位的发生率显著更高（P小于0.01）。
