影像学检查对结肠癌诊断价值的临床研究

目的　探讨对结肠癌诊断的影像学检查程序。方法　对经手术病理证实的 82例结肠癌的结肠气钡双重造影、纤维内镜、常规腹部B型超声和CT检查进行对比研究。结果　结肠气钡双重造影、纤维内镜、B型超声、CT扫描的病灶检出率分别为90 .1%、89.5 %、5 3 .8%和 5 3 .3 % ,前两者与后两者之间差异显著 (Ρ <0 .0 5 )。肝脏转移瘤诊断符合率B型超声、CT扫描为 10 0 %。结论　结肠气钡双重造影和结肠内镜是结肠癌筛选的重要方法 ,B型超声、CT扫描所见是结肠癌术前分期的可靠依据

The Evaluation of Imaging Examination in the Diagnosis of Colon Cancer

Objective To study the procedure of imaging examination for the patients with colon cancer.Methods The comparative study on ultrosonograph, pneumobarium double contrast examination, colonscopy and CT in 82 cases with colon carcinoma comfired by operation and pathalogy were carried out.Results The detective rate of colon cancer was 90.1%,89.5%,53.8% and 53.3% by pneumobarium double contrast examination,colonscopy ultrosonography and CT respectively.The detective rate of metastasis in liver was 100% by ultrosonograph and CT.Conclusion Pneumobarium double contrast examination and colonoscopy are the main methods for diagnosis of colon cancer. Ultrosonography and CT are the important methods in evaluating the stage of colon carcinoma before operation.
