摘要
目的 :评价多层螺旋CT(MSCT)与数字胃肠对溃疡型胃癌的诊断价值及影响因素。方法 :经手术病理证实的溃疡型胃癌 34例 ,手术前 1周分别行MSCT和数字胃肠检查。所有MSCT图像 (包括轴位、CTVG、SSD、Raysum)和数字胃肠图像 (经后处理的多相位图像 )分别由 2位胃肠组放射医师实行双盲阅片 ,阅片结果分别与手术标本及病理比较。结果 :34例患者的 38个溃疡 ,MSCT检出 35个 ,数字胃肠检出 37个 ;MSCT定位正确 35个 ,数字胃肠定位正确 37个 ;MSCT定性正确 35个 ,数字胃肠定性正确 36个。对 34个进展期癌的BorrmannⅡ、Ⅲ型分型 ,MSCT正确 31个 ,数字胃肠正确 2 2个。结论 :在溃疡型胃癌的检出、定位、定性方面 ,MSCT与数字胃肠无显著性差异 ,在BorrmannⅡ、Ⅲ型分型方面 。
Objective:To evaluate the clinical applications of multi slice CT (MSCT) and directly digital X ray device (DDXRD) in the diagnosis of gastric ulcerated carcinoma.Methods:34 patients with gastric ulcerated carcinoma proved by surgical pathology were examined by MSCT and DDXRD before operation.All images of MSCT (including multi planar reconstructions,CTVG,SSD,Ray sum) and DDXRD were viewed respectively by two groups of radiologists separately.The results of MSCT and DDXRD were compared by postoperative pathology respectively.Results:There are 38 ulcerative lesions detected by surgery and pathology,in which 35 were detected on MSCT,and 37 were detected on DDXRD;while 34 were localized correctly on MSCT and 37 on DDXRD;35 were diagnosed correctly on MSCT,and 36 on DDXRD.The correct classifications of Borrmann Ⅱ and Ⅲ in 34 advanced ulcerated carcinoma were 31 on MSCT,and 22 on DDXRD.Conclusion:MSCT is superior to DDXRD in Borrmann classification.
