1、多层螺旋CT对结直肠癌诊断的应用价值1北京市房山区妇幼保健院放射科北京102488,2西安医学院第二附属医院放射科西安710038摘要：目的探讨多层螺旋CT对结肓肠癌诊断的应用价值。方法回顾性分析了我院2012年3月~2014年9月经手术治疗，病理证实的结直肠癌32例患者的病历资料。术前对所有患者行CT平扫和三期扫描，并做图像后处理，将多层螺旋CT表现与手术和病理结果进行比较。结果木组病理为黏液腺癌6例，中管状腺癌22例，绒毛状腺癌2例、混合型腺癌2例。CT表现，升结肠癌8例，横结肠癌2例，降结肠癌6例，乙状结肠癌3例，直肠癌13例。肿瘤形成肠腔狭窄和形态不规则21例，形成腔内肿块口
2、例；局部肠壁增厚32例；CT上表现15例显示为浆膜面受侵，手术发现17例浆膜面受侵，淋巴结转移者CT发现18例，病理证实22例。结论多层螺旋CT的多期扫描结合多种后处理技术，不但能明确结肓肠癌病灶的部位、大小，还能明确病变浸润深度、病变与周围脏器的关系以及有无邻近淋巴结转移或（和）其他脏器转移等，为临床大夫术前正确的评价病变并决定手术方式提供了准确客观依据。关键词：多层螺旋CT；多期扫描；大肠癌；诊断价值ValueofMulti-sliceCT(MSCT)intheDiagnosisofColorectalCancerWANGXiangl,LUOChunhai2(X-rayDepar
