摘要：目的：研究分析多层螺旋CT在进行肠梗阻放射诊断方面的价值和效果。方法：按照研究排除纳入要求选取我院在2020/6-2021/6月时间段内收治的肠梗阻患者共80例，患者接受多层螺旋CT检查和腹部X线检查，数据结果为实验组和对照组，对比两组数据的诊断准确率与手术病理吻合性。结果：采用多层螺旋CT进行肠梗阻诊断准确率与手术病理吻合性均明显高于常规腹部X线检查，差异有统计学意义（P<0.05）。结论：在肠梗阻放射诊断中采用多层螺旋CT进行诊断准确率极高，同时诊断结果与手术病理吻合度极高，表明该办法能够为疾病诊断和手术开展提供有效的参考信息，具有极高的利用价值。

Objective： To study and analyze the value and effect of multi-slice spiral CT in radiation diagnosis of intestinal obstruction. Methods： according to the requirements of exclusion， 80 patients with intestinal obstruction in our hospital from June 2020 to June 2021 were selected. The patients received multi-slice spiral CT examination and abdominal X-ray examination. The data results were the experimental group and the control group. The diagnostic accuracy of the two groups was compared with the surgical pathology. Results： the accuracy of MSCT in the diagnosis of intestinal obstruction was significantly higher than that of conventional abdominal X-ray examination （P < 0.05）. Conclusion： the diagnostic accuracy of multi-slice spiral CT in the radiation diagnosis of intestinal obstruction is very high， and the diagnostic results are highly consistent with the surgical pathology， which indicates that this method can provide effective reference information for disease diagnosis and operation， and has high utilization value.

腸梗阻是一种多原因多因素导致的肠内容物通过障碍疾病，在临床中，该疾病的一般致病因为肠炎、疝气、肠粘连等，患者临床表现为呕吐、便秘、腹痛以及无粪便排气等情况[1]。本研究讨论多层螺旋CT对于肠梗阻的诊断效果，研究内容如下。

1资料与方法

1.1一般资料

选取患者共80例，男女比例42/38，患者年龄28-75岁，平均年龄（49.1±18.9）岁。

1.2方法

1.2.1X线检查患者分别接受X线检查与多层螺旋CT检查，X线检查按照常规拍照方式进行取片，馆擦汗患者具体情况进行卧位拍拍片。

1.2.2多层螺旋CT诊断采用西门子64排螺旋CT机进行检查，参数设置：层厚5mm，层距5mm，球管电压120Kv，球管电流320mA。首先进行常规平扫，在平扫完成后进行腹部螺旋双期扫描。对比剂选择非离子型对比剂，增强扫描应当延迟扫描2min。……
