| 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。

| Abstract: | Objective: To evaluate the electron beam computed tomography(EBCT) three-dimensional reconstruction in the diagnosis of bowel obstruction.Methods: Seventy-eight patients suspected of bowel obstruction underwent EBCT with two-phase 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. |
