摘要
目的旨在探讨结肠癌多期增强MSCT影像学表现与术后病理特点。方法选取我院2017年9月至2019年1月收治的结肠癌患者73例,患者均进行了MSCT检查,收集73例患者临床资料及影像学资料,总结患者MSCT影像学表现,以手术病理结果为金标准,计算MSCT对结肠癌T分期的诊断准确率。结果 MSCT检查对结肠癌T1-2、T3、T4分期的诊断正确率分别为88.46%(23/26)、88.88%(24/27)、100.00%(20/20),总诊断正确率为91.78%;MSCT图像中,结肠癌最大肿块大小为7.42cm×4.10cm,T1期患者图像主要表现为肠壁局限性增厚,大于0.5cm,肠腔内未见明显狭窄,T2期患者肠外壁光滑,周围脂肪结构清晰;T3期患者肠壁可见局限性增厚,肠外壁毛糙,但未见毗邻组织受侵;T4期患者MSCT平扫肠腔明显变窄,外周脂肪密度出现增高,14例患者可见明显条索状高密度影,同时侵犯临近周围器官,可见直径为3~12mm的肠旁淋巴结,淋巴结转移9例,后均经术后病理证实,合并梗阻者11例;乙状结肠局部管壁增厚动脉期呈明显强化,静脉期及延迟期呈现持续强化。结论 MSCT可有效显示结肠癌图像特征,MSCT检查对结肠癌T分期诊断正确率高,有一定临床应用价值。
Objective To explore the imaging findings of colon cancer in multi-phase enhanced MSCT and postoperative pathological features.Methods 73 patients with colon cancer admitted to our hospital from September 2017 to January 2019 were enrolled.All patients underwent MSCT examination.The clinical data and imaging data of 73 patients were collected.The MSCT imaging findings were summarized.The surgical pathological results were used as the gold standard to calculate the diagnostic accuracy of MSCT for colon cancer in T stage.Results The diagnostic accuracy of MSCT in the diagnosis of colon cancer of T1-2,T3,and T4 stages was 88.46% (23/26),88.88% (24/27),and 100.00% (20/20),respectively.The overall diagnostic accuracy was 91.78%.In MSCT images,the largest size of colon cancer was 7.42cm×4.10cm.The image of patients with T1 stage was mainly characterized by localized thickening of the intestinal wall,more than 0.5cm,and there was no obvious stenosis inside the intestinal cavity.In T2 stage,the intestinal wall of the patient was smooth and the surrounding fat structure was clear.In the T3 stage,the intestinal wall of the patient was locally thickened,and the intestinal exine was rough,but adjacent tissues were not invaded.In the T4 stage,the intestinal cavity was significantly narrowed in MSCT,and the peripheral fat density was increased.14 patients showed obvious high-density shadows with strip shape,which invaded adjacent organs at same time.lymph nodes with diameter of 3~12mm beside intestines were seen.There were 9 cases with lymph node metastasis confirmed by postoperative pathology,and 11 cases combined with obstruction.The local wall of the sigmoid colon was thickened,was significantly enhanced in arterial phase and showed continuous enhancement in the venous phase and the delayed phase.Conclusion MSCT can effectively display the characteristics of images of colon cancer.MSCT examination has a high diagnostic accuracy for colon cancer in T staging,and has clinical application value to some extent.
