作者对35例钝性创伤致肾损伤病人的螺旋CT作了回顾性研究。口服对比剂后,以2ml/s静脉注射100ml对比剂根据标准程序完成腹部和盆腔的最初CT。在静脉注射对比剂开始后延迟60s,均用螺旋技术扫描获得CT影像。 结果显示,3例在最初CT确定无对比剂外渗,后在延迟扫描上检出肾脏收集系统损伤。这3例均因各种原因获得重复CT扫描。这种所见结果已改变了肾创伤初始的CT诊断。例1,男性,30岁。在创伤后作了脾切除,肝和结肠的损伤修补,术后病人有 The authors retrospectively studied the spiral CT of 35 patients with blunt trauma-induced renal injury. After oral contrast agent, an initial CT of the abdomen and pelvis was done according to standard procedures with 100 ml of contrast agent intravenously injected at 2 ml / s. Delayed 60s after intravenous injection of contrast agent began, and CT images were obtained by spiral technique. The results showed that in the first three cases, no extravasation of the contrast medium was confirmed by CT, and the renal collecting system was detected on the delayed scan. All three cases had multiple CT scans for a variety of reasons. This finding has changed the initial CT diagnosis of renal trauma. Example 1, male, 30 years old. After the trauma was splenectomy, liver and colon injury repair, patients have
