摘　　要：目的:进一步认识16层螺旋CT平扫对急性腹部创伤少见脏器损伤的诊断价值。方法:990例急性腹部创伤患者,在未口服造影剂情况下行16层螺旋CT平扫,分析其CT图像,发现肾上腺、胰腺、空腔脏器和系膜血管等少见损伤,所有病例均经剖腹术或CT随访,把CT初诊结果与手术及随访结果进行比较,观察CT平扫诊断腹部创伤少见脏器损伤的敏感性及特异性。结果:990例腹部创伤患者中,初诊肾上腺损伤12例,胰腺损伤17例,空腔脏器或系膜损伤26例。与手术及随访结果比较,发现肾上腺的假阳性0例,假阴性0例,诊断敏感性为100%,胰腺损伤的假阳性2例,假阴性3例,诊断敏感性为83.3%;空腔脏器损伤的假阳性7例,假阴性6例,诊断敏感性为76%。结论:多层螺旋CT对急性腹部创伤少见脏器损伤具有较高诊断价值,对肾上腺损伤的诊断敏感性及特异性较高,对空腔脏器及系膜血管损伤诊断的敏感性相对较低。Objective：To recognize the diagnostic value of emergency unenhanced CT without oral contrast material in the diagnosis of infrequent abdomen injury.Methods：990 patients with abdomen symptoms underwent plain scan using 16-row spiral CT without oral contrast material;their CT pictures were noted to find adrenal gland,pancreas,and hollow viscus injure.All cases underwent laparotomy or follow-up CT visit.The initial CT results were compared with the operative and follow-up outcome.Results：In the 990 patients with abdomen symptoms,there were 12 cases of adrenal gland injuries;17 cases of pancreas injuries,and 26 cases of hollow viscus injuries.Compared with operative and follow-up outcome,there was 0 false-negative and 0 false-positive in adrenal gland injury and the sensitivity was 100%;there were 2 false-negatives and 3 false-positives in pancreas injury and the sensitivity was 83.3%;there were 6 false-negatives and 7 false-positives in hollow visceral injury and the sensitivity was 76%.Conclusion：16-slice spiral CT has high diagnostic value in acute infrequent abdomen injury,The diagonostic sensitivity is higher to adrenal gland injury,but relatively lower to hollow viscus injury.
