摘　　要：目的:探讨超高速CT(EBCT)三维重建技术在肠梗阻诊断中的应用价值。方法:回顾分析78例临床怀疑为肠梗阻患者的CT扫描检查结果。所有患者均进行双期增强扫描,32例行MPR-冠状位、矢状位图像重建,并将CT确诊为肠梗阻的患者与临床检查结果对照。结果:78例患者中EBCT提示肠梗阻者73例,经手术后病理证实或临床随访证实者共73例,与临床结果完全符合,EBCT对诊断肠梗阻的敏感性达100%;其中66例CT作出明确诊断,准确性达90.4%,对病因诊断的符合率达86.3%。结论:EBCT三维重建技术的应用,在肠梗阻的定位诊断、病因诊断和血供情况的了解具有极大的优势,已成为诊断肠梗阻的重要检查方法。Objective ： To evaluate the electron beam computed tomography （EBCT） three-dimensional reconstruction in the diagnosis of bowel obstruction. bowel obstruction underwent EBCT with two-phase Methods： Seventy-eight patients suspected of enhancement scanning and 32 of them were re-established by corona-MPR and sagittal-MPR. All the EBCT results were analyzed and compared with the clinical findings. Results ： Seventy-three of the cases were diagnosed as bowel obstruction by EBCT, which were all confirmed by surgery or follow-up, with an accuracy rate of 100% for location diagnosis and 86.3% for etiology Conclusion： EBCT 3D-reconstruction has great advantages in determining the location, etiology and blood-supply of bowel obstruction.
