目的:研究混合细胞性肝癌的CT和MRI诊断的疗效。方法:随机选取我院在2008年10月-2011年12月期间收治的30例混合细胞性肝癌患者作为研究对象,回顾性分析其CT和MRI的影像表现。本组30例混合细胞性肝癌患者中,有27例患者采用的是CT进行检查,6例患者采用的是MRI进行检查,5例同时选用CT和MRI进行检查,2例仅行MRI检查。结果:27例患者CT平扫所有瘤灶都是团块状低密度灶或结节状,边界清楚或模糊。CT增强扫描的强化方式主要有3种:I型为快进快出型(6例),11型为慢进慢出型(14例),III型为此起彼伏型(7例)。6例MRI平扫TlWl上病灶基本是均匀低信号,T2WI上是等高信号,并且内有不规则低信号区。增强扫描表现为2种不同的强化方式:I型(快进快出型,3例);IlI型(此起彼伏型.3例),该3例中有2例仅采用MRI进行检查。综合采用CT和MRI进行检查,一共有10例呈此起彼伏型。结论:绝大多数混合细胞性肝癌的CT和MRI表现不具有特征性,但部分病例呈现此起彼伏型的强化方式有利于诊断本病。
Objective: To study the CT and MRI diagnosis of mixed cell carcinoma of liver. Methods: Thirty patients with mixed-cell hepatocellular carcinoma who were treated in our hospital from October 2008 to December 2011 were randomly selected as the research object. The CT and MRI findings were retrospectively analyzed. Of the 30 patients with mixed-cell hepatocellular carcinoma, 27 were examined by CT, 6 were examined by MRI, 5 were examined by CT and MRI, and 2 were MRI-only. Results: CT scan of 27 patients had lumps or low nodules with clear or obscured boundaries. There are three types of enhancement in CT enhanced scanning: type I is fast-forward type (6 cases), type 11 is slow-moving type (type 14) and type III is type-after-type (type 7). 6 cases of MRI plain TlWl lesion is basically a uniform low signal, T2WI is a high signal, and there are irregular low signal area. Enhanced scanning showed two different intensification methods: type I (fast forward fast type, 3 cases); IlI type (one after another type .3), of which 3 cases were only examined by MRI. Comprehensive use of CT and MRI examination, a total of 10 cases were one after another. CONCLUSION: CT and MRI manifestations of most mixed-cell hepatocellular carcinoma are not characteristic, but in some cases, the intensified mode of one after another is helpful to diagnose the disease.
