目的:探讨肝内周围型胆管细胞癌CT和MRI诊断以及其病理学基础。方法:选取我院2014年4月~2015年4月在我院就诊的40例肝内周围型胆管细胞癌患者作为研究对象,所有患者均行MRI和CT诊断,并分析影像学特征及其病理基础。结果:CT扫描结果发现患者肿块呈现出低密度或略低密度,34例患者病灶边界较不清晰,延迟后有37例患者扫描内部强化显著,肿块呈现出向心性强化;MRI扫描结果发现肿块在T2WI上表现为不均匀性高信号;36例患者增强扫描发现病灶边缘处强化;与单纯CT诊断相比,CT联合MRI诊断符合率之间比较差异显著具有统计学意义(p<0.05)。结论:CT联合MRI可明显提高肝内周围型胆管细胞癌患者早期病症诊断率,该方法具有临床推广应用价值。
Objective: To investigate the CT and MRI diagnosis of intrahepatic peripheral cholangiocarcinoma and its pathological basis. METHODS: Forty patients with intrahepatic peri-intestinal cholangiocarcinoma who were diagnosed in our hospital from April 2014 to April 2015 were selected as the study subjects. All patients underwent MRI and CT diagnosis. Imaging features and pathology were analyzed. basis. RESULTS: CT scans showed a low or slightly lower density of the patient’s mass. The borders of the lesions were less clear in 34 patients. After the delay, 37 patients had significant internal scan enhancement and the mass showed centripetal enhancement. The MRI scan revealed a mass on T2WI. On the performance of heterogeneous high signal; 36 cases of enhanced scans found lesions at the edge of the enhancement; compared with simple CT diagnosis, CT combined MRI diagnosis of the difference between the statistically significant difference (p <0.05). Conclusion: CT combined with MRI can significantly improve the early diagnosis rate of patients with intrahepatic peripheral cholangiocarcinoma. This method has clinical application value.
