MSCT对胃肠急腹症诊断价值【摘要】目的：探讨多层螺旋CT在胃肠急腹症诊断中的应用价值。材料与方法：80例临床可疑胃肠急腹症病例行MSCT检查，并结合其多平面重组（MPR）、最大密度投影（MIP）等多模式重组对图像进行分析诊断，全部病例均经手术或临床随访证实。结果：80例可疑病例中有胃肠疾病引起急腹症61例，其中MSCT诊断58例，能显示病变的部位、程度、病变周围情况。53例与临床相一致，5例误诊。3例MSCT未发现明显异常。结论：利用MSCT 的多模式重组，并结合轴位图像能提高胃肠急腹症诊断的准确性，在急腹症病因诊断中具有重要价值。 【关键词】急腹症；诊断；体层摄影术 X线计算机 The Diagnostic Value of MSCT in Acute Abdomen by Gastrointestinal Disorders SHI Lei1,2, ZHANG Zili2.

China 【Abstract】Objective To investigate the value of MSCT in the diagnosis of acute abdomen by gastrointestinal disorders. Materials and Methods80 cases of suspicious clinical cases of gastrointestinal diseases abdomen were all examined using MSCT with multi-modal reorganization such as multiplanar reconstruction (MPR), maximum intensity projection (MIP) image, all cases were confirmed by surgery or clinical follow-up confirmed. Results80 cases of suspected cases of gastrointestinal disease has one of 61 cases of acute abdomen, one of MSCT diagnosis of 58 cases showing the lesion site, the extent of lesions surrounding circumstances. One of 53 cases is consistent with clinical, 5 cases of misdiagnosis. Example 3 did not find significantly abnormal in MSCT. ConclusionMultimodel reconstruction techniques combinated with axial images of MSCT are of important value in making a correct diagnosis of acute abdomen by gastrointestinal disorders. 【Key words】Acute abdomenDiagnosisTomographyX-ray computed 胃肠疾病是临床急腹症的常见病因，其特点是常因病史隐匿或症状不典型而诊断困难，传统检查手段如X线平片，精确定位及定性诊断存在限度。 而MSCT具有快速采集、单次扫描覆盖范围大、亚毫米层厚、更高的空间分辨率及强大的图像后处理功能等优点，可清晰显示胃肠形态、胃肠壁及腔内改变，使得MSCT对急腹症的诊断更加快速、无创和便捷。笔者现将我院2005年5月-2009年4月80例急腹症病例的MSCT检查资料进行分析，进一步探讨其诊断价值。 1材料与方法 1.1临床资料 本组80例可疑急腹症病例，男44例，女36例。年龄15-79岁。所有患者均有不同程度的急性腹痛症状，部分患者有放射痛、腹胀、呕吐、肛门停止排气排便等伴随症状。 1.2检查方法 采用GE公司 Lightspeed16 MSCT行轴位平扫，扫描范围从膈顶至耻骨联合；对于怀疑动静脉血栓性病变以及消化道出血病变加做MSCT双期增强扫描，
