多层螺旋CT的后处理重建在急性肠梗阻中的临床应用分析

Clinical Application of Post-treatment Reconstruction of MSCT in Acute Intestinal Obstruction

目的:探讨平扫多层螺旋CT(MSCT)的多平面重建(MPR)与曲面重建(CPR)在急性肠梗阻中的应用价值,为临床及时诊治提供更有力依据。方法:随机选取我院2018年4月—2021年4月经临床诊断且手术证实的肠梗阻患者60例,所有患者均以横断面为基础联合MPR及CPR检查。利用双盲法对比仅横断面图像为对照组,以横断面为基础联合MPR及CPR为实验组。分析术前平扫影像资料。结果:两种研究方法检出肠梗阻均敏感,实验组对肠梗阻的病因及绞窄预测符合率分别为98.3%(59/60)、98.3%(59/60),明显高于对照组的76.7%(46/60)、81.7%(49/60),差异有统计学意义(P<0.05)。结论:MPR和CPR作为横断面图像的补充,联合横断面诊断肠梗阻患者的定位、定性诊断以及预测绞窄与否符合率高,值得临床应用。

Objective To investigate the application value of multiplanar reconstruction(MPR)and curved reconstruction(CPR)of plain scan multislice spiral CT(MSCT)in acute intestinal obstruction,and to provide a more effective basis for clinical diagnosis and treatment.Methods A total of 60 patients with ileus who were clinically diagnosed and surgically confirmed in our hospital from April 2018 to April 2021 were randomly selected.All patients were examined with MPR and CPR on a cross-sectional basis.Doubleblind method was used to compare cross-sectional images only as the control group,and cross-sectional images combined with MPR and CPR as the experimental group.The preoperative plain scan image data were analyzed.Results Both methods were sensitive to intestinal obstruction.The coincidence rate of etiology and strangulation prediction in the experimental group was 98.3%(59/60)and 98.3%(59/60),respectively,which was significantly higher than that in the control group(76.7%(46/60)and 81.7%(49/60),and the difference was statistically significant(P<0.05).Conclusion MPR and CPR,as a supplement of cross-sectional images,have high coincidence rate of localization,qualitative diagnosis and prediction of strangulation in patients with intestinal obstruction,and are worthy of clinical application.
