目的 探讨CT增强延时扫描对肾损伤诊断的临床价值。方法 对 9例肾损伤病人行螺旋CT普通扫描、增强扫描和增强延时扫描。结果 CT普通扫描显示肾轮廓不规则 5例 ,肾包膜下血肿 3例 ,肾周积血 2例。CT增强扫描和延时扫描不仅显示普通扫描所见 ,而且显示外伤性假性动脉瘤形成 1例 ,肾收集系统损伤导致尿外瘘 2例 ,肾皮质穿通伤伴局限性肾包膜下陈旧积血 1例 ,肾皮质裂伤 1例 ,肾积水破裂导致腹腔积液 1例。结论 CT增强延时扫描在肾损伤、尤其是收集系统损伤的诊断中很有价值
Objective To investigate the clinical value of CT enhanced delayed scan in the diagnosis of renal injury. Methods Nine cases of renal injury patients underwent spiral CT scan, enhanced scan and enhanced delayed scan. Results CT scan showed irregular renal outline in 5 cases, 3 cases of renal subcapsular hematoma, 2 cases of renal hemorrhage. CT enhanced scan and delayed scan not only show the general scan seen, but also showed the formation of traumatic pseudoaneurysm in 1 case, renal collecting system damage caused by 2 cases of urinary fistula, renal cortical penetrating injury with limited renal capsule under the old product 1 case of blood, 1 case of renal cortical laceration, hydrocephalus ruptured in 1 case caused by ascites. Conclusions CT-enhanced delayed scan is valuable in the diagnosis of renal injury, especially of the collection system
