摘    要:目的:探讨MSCT低张水灌肠技术在大肠癌诊断中的应用价值。方法:选取临床和/或纤维结肠镜检查拟诊大肠癌患者70例作为研究对象(排除严重肠梗阻患者)。所有患者均行MSCT低张+水灌肠+体位扫描+三期动态增强扫描。由2名高年资放射科医师阅片,重点观察病变部位、大小、形态、肠壁厚度及分层情况,病变强化特征,浆膜面改变,肠周脂肪间隙,邻近血管,淋巴结及远处脏器。防止遗漏小病灶。以术后病理TNM分期为金标准,采用诊断性试验,判断MSCT对大肠癌分期的敏感性、特异性及准确度。结果:70例大肠癌MSCT全部检出,病变位于升结肠13例,横结肠2例,降结肠3例,乙状结肠21例,直肠31例。本组61例低张水灌肠效果满意,较好显示病变部位、形态、长度及肠壁侵犯深度,9例肠管未充分扩张,肿瘤境界显示不满意,其中升结肠3例.肝曲结肠1例,直肠下段5例。病变处肠壁不规则增厚,部分肿块形成,最大约12.5cm×10.3cm。病变最长约15.0cm。病变不同程度强化.明显强化者占82.86%(58/70),强化幅度平均为(43.5±15.7)HU。大肠癌TNM分期准确度为87.14%(61/70).其中T分期准确度为88.57%(62/70)。N分期准确度为87.14%(61/70),M分期准确度为90%(63/70)。结论:MSCT低张水灌肠技术能较清楚的显示病灶部位、大小、形态、长度、肠壁浸润深度。对大肠癌术前分期准确度较明显提高。但对于升结肠近端及直肠下段肿瘤病变显示有一定限度。

关 键 词:结肠癌  肿瘤分期  灌肠  体层摄影术  X线计算机

Abstract:Objective:To evaluate the value of multi-slice spiral CT(MSCT) with hypotonic water enema in diagnosis of colorectal carcinoma.Methods:70 cases of colorectal carcinoma suspected by clinical and/or fibercolonoscopy(severe colon obstruction patients were excluded) were included in the study.All patients had underwent hypotonic water enema,spiral CT,position and three phase dynamic enhanced scan.Two senior radiologists read CT images,focused on observation of lesions,size,shape,wall thickness and delamination,...
