摘　　要：目的探究64层螺旋CT仿真内窥镜在鉴别结、直肠病变中的应用价值。方法回顾分析本院2017年7月至2019年4月收治的90例结、直肠疾病患者的临床资料,观察MSCT检查平扫和增强扫描的影像特点,以纤维结肠镜对结、直肠癌的诊断结果作为“金标准”,比较CTVE与纤维结肠镜对结、直肠癌的检出率及对结、直肠息肉、慢性结、直肠炎及溃疡性结、直肠炎的检出情况。结果90例患者经纤维结肠镜,其中22例患者为结、直肠癌;29例慢性结、直肠炎;20例结、直肠息肉;19例溃疡性结、直肠炎;经CTVE技术检出结、直肠癌21例,占23.33%;结、直肠息肉27例,占30.00%;慢性结、直肠炎19例,占21.11%;溃疡性结、直肠炎10例,占11.11%。其中对溃疡性结、直肠炎的检出率较差,对结、直肠病变的总检出率为85.56%。结论64层螺旋CT仿真内窥镜在鉴别结、直肠病变中具有重要的价值,临床上可对该检查的影像学特征进行全面分析,结合患者表现出的临床特征对结、直肠病变进行诊断和治疗。Objective To explore the application value of 64-slice spiral CT virtual endoscopy in the diagnosis of colorectal lesions.Methods The clinical data of 90 patients with colorectal diseases admitted to our hospital from July 2017 to April 2019 were retrospectively analyzed.The imaging features of plain and enhanced scans of MSCT were observed.The diagnosis of colorectal cancer by fibro-colonoscopy was used as a"gold standard"to compare the detection rate of colorectal cancer,polyp of rectum and colon,chronic nodules and proctitis,and ulcerative colitis between CTVE and fibro-colonoscopy.Results 90 patients underwent fiberoptic colonoscopy.Among them,22 patients were colorectal cancer,29 patients had chronic nodules and proctitis,20 patients had polyp of rectum and colon,19 patients had ulcerative colitis.CTVE technique detected 21 cases with colorectal cancer,accounting for 23.33%,27 cases with polyp of rectum and colon,accounting for 30.00%,19 cases with chronic nodules and proctitis,accounting for 21.11%,and 10 cases with ulcerative colitis,accounting for 11.11%.Among them,the detection rate of ulcerative colitis is poor.The total detection rate of colorectal lesions was 85.56%.Conclusion The 64-slice spiral CT virtual endoscopy has important value in the identification of colorectal lesions.The imaging features of the examination can be comprehensively analyzed in clinic.The clinical features exhibited by the patient can be combined to diagnose and treat the colorectal lesions.
