多层螺旋CT在肠梗阻诊断中的价值

Value of multi-slice spiral CT in diagnosing of bowel obstruction

目的:探讨多层螺旋CT在肠梗阻诊断中的价值。方法:回顾分析57例临床、CT及手术资料齐全的肠梗阻患者,其中21例为单纯CT平扫,36例在平扫基础上行增强扫描,其中三期动态增强12例,将CT原始数据进行MPR冠状、矢状重建,分析CT表现,并与手术结果对照。结果:CT诊断梗阻56例,符合率98%;确定梗阻部位48例,符合率88.9%;确定梗阻原因47例,符合率82.5%;10例血供障碍患者,CT检出7例,符合率70.0%。结论:多层螺旋CT在诊断肠梗阻的有无、梗阻部位及梗阻原因方面具有较高的价值,对确定有无血运障碍也具一定价值。

Objective：To investigate the value of MSCT （muhi-slice spiral CT） in the diagnosis of bowel obstructions. Methods： Fifty-seven patients with surgically or clinically confirmed diagnosis of bowel obstructions underwent 1f-slice CT examinations of the en- tire abdomen. All cases had plain CT scans, while 36 cases had additional contrast enhanced CT Scans, and 12 patients were examined by triphase spiral CT. In addition to the conventional axial images, the original CT raw data were then reconstructed into both coronal and sagittal images by using MPR techniques. Imaging findings were analyzed on axial, MPR coronal and sagittal images and were compared with surgical results. Results： The CT images correctly depicted that 57 patients （98%） had bowel obstructions. The site of bowel obstructions were determined in 48 patients （ 88.9% ）, and the underlying etiology of bowel obstructions were determined in 47 patients （82. 5% ）. Seven lesions were diagnosised among 10 patients with bowel ischemia, 70.0% of the patients with bowel ischemia were correctly depicted. Conclusion： MSCT is very useful for evaluating the presence of bowel obstructions, the site and etiology of bowel obstruction, as well as the circulation status of bowel loop.
