摘　　要：目的利用MSCT三维重建技术分析及评估结肠癌侵犯范围,并与病理学结果进行对比研究。方法回顾性分析本院2017年2月至2021年12月收治的87例结肠癌患者的临床资料,所有患者均进行MSCT检查。对患者所得MSCT灌注图像进行分析,了解结肠癌患者侵犯范围对比MSCT平扫、MSCT三维重建与病理结果一致情况。结果87例患者共有90个病灶,其中侵及结肠粘膜层5个,粘膜下层10个、固有肌层27个,全层48个。MSCT平扫在粘膜层、粘膜下层、固有肌层与病理结果比较均存在差异,与病理结果符合率差(P<0.05);三维重建与病理结果比较差异无统计学意义,对固有肌层、结肠全层侵犯检出率均为100.00%(P>0.05);MSCT表现:肠腔内偏心性分叶状肿块,肠壁表现为环形或半环形增厚;侵犯广泛者可见其肠壁僵硬,肠腔狭窄如革袋胃;粘液腺癌病灶密度较低,表现为水样密度区,肝转移、淋巴结肿大患者均为低密度,偶见钙化灶。结论使用MSCT三维重建技术可直观了解结肠癌患者病变基本情况,对结肠癌侵犯范围评估与病理检查一致性较高,可为临床诊断提供全面参考信息。Objective To analyze the MSCT three-dimensional reconstruction technology to evaluate the extent of colon cancer invasion,and compare it with pathological results.Methods The clinical data of 87 patients with colon cancer treated in our hospital from February 2017 to December 2021 were collected as the research object and were retrospectively analyzed.All patients were examined by MSCT.The patients'MSCT perfusion images were analyzed to understand the extent of invasion of colon cancer in patients.The results of MSCT plain scan,MSCT 3D reconstruction and pathological results were compared.Results 90 lesions were found in 87 patients,including 5 lesions invading colonic mucosal layers,10 lesions invading submucosal layers,27 lesions invading muscularis propria,and 48 lesions invading full-thickness.There were differences in the MSCT scan between the mucosal layer,submucosa,muscularis propria and pathological results,the coincidence rate with pathological results was poor(P<0.05).There was no statistically significant difference between the three-dimensional reconstruction and the pathological results,and the detection rate of invasion of the muscularis propria and the full-thickness of colon was 100.00%(P>0.05).MSCT showed a partial lobular mass in the intestinal cavity,and the intestinal wall was thickened in a circular or semi-circular shape.The patients with extensive invasion can be seen in the stiffness of intestinal wall.The intestinal cavity is narrow like a pouch stomach.The density of mucinous adenocarcinoma was relatively low,showing density zone like water.Patients with liver metastases and lymphadenopathy had low density,with occasional calcifications.Conclusion The use of MSCT three-dimensional reconstruction technology can intuitively understand the basic conditions of patients with rectal cancer,and it is highly consistent with the evaluation of invasion range of rectal cancer.and can provide comprehensive reference information for clinical diagnosis.
