摘要
目的:探讨增强 CT 联合多向调整多平面重建技术(MPR)在术前评估进展期胃癌胃壁浸润深度中的价值。方法收集经手术确诊为进展期胃癌且术前行腹部增强 CT 的患者105例,经薄层数据传至后处理工作站进行多向调整 MPR,显示胃癌最大病变为最佳图像,对重建后的图像对胃癌病灶进行 T 分期,并与术后病理 T 分期相对比。结果病理诊断 T1期9例,T2期23例,T3期46例,T4期27例;增强 CT 联合多向调整 MPR 技术对 T1、T2、T3、T4期诊断的准确率为98.1%、93.3%、86.7%、91.4%。结论采用增强 CT多向调整 MPR 技术可提高胃癌 T 分期诊断的准确性,可以作为一种评估胃癌分期的方法。
Objective To explore the evaluation of contrast enhanced CT with multi -direction adjusting multi -planar reformation(MPR)on the stomach wall invasion of advanced gastric cancer.Methods 105 cases of advanced gastric cancer proved by pathology after surgery were checked by contrast enhanced CT before surgery.All the images were reconstructed by multi -direction adjusting MPR to show perfectly the lesions of gastric cancer,T stage diagnosed by CT were compared with the T stage diagnosed by pathology.Results T1,T2,T3,T4 stage diag-nosed by pathology were 9 cases,23 cases,46 cases and 27 cases respectively,the accuracy of multi -direction adjus-ting MPR in diagnosing T1,T2,T3,T4 stage were 98.1%,93.3%,86.7%,91.4% respectively.Conclusion Con-trast enhanced CT with multi -direction adjusting MPR can improve the accuracy in diagnosing the T stage of ad-vanced gastric cancer,which can be used to evaluate the staging of advanced gastric cancer.
