肝包虫病的MRI表现

目的：分析肝包虫病的MRI表现,以提高对其的认识。方法：回顾性分析肝包虫病12例,其中肝细粒棘球蚴8例,肝泡状棘球蚴4例。5例做MRI水成像,4例做血管MRI成像,全部做MRI平扫加增强扫描检查。结果：肝细粒棘球蚴为圆形或类圆形边缘光滑锐利的影像,T1WI呈低信号,T2WI呈高信号,囊壁厚度均匀一致。在T2WI上低信号和多房性子囊为其特征性表现。泡状棘球蚴呈不规则实性肿块,T1WI、T2WI均以低信号为主,尤其是在T2WI上的低信号是其特征性表现。MRCP水成像和MRA血管成像技术的运用,能够清楚显示肝包虫病灶的细微结构、病灶与胆道及病灶与血管的关系。结论：MRI可以检出肝包虫寄生的部位、种类、形态、大小、与邻近器官的关系,对不同病理变化的相应的分型和肝脏非寄生虫性占位病变的鉴别诊断。

MRI represent of the hepatic echinococcosis

Objective: To analysis MRI represents of the hepatic echinococcosis, and improve the cognition of it. Methods: Twelve cases of hepatic echincoccosis were analyzed eight of those are Evaluation of hepatic alveolar echinococcosis, and the remainders four are were done by Echinococcosis. Alveolar five patients veceived MRH examination, and 4 of them receired MRA. All of those the MRI plain scan and boost up scan. Results: The imaging of the Hydatid cyst of liver shows itself rotundity or analogy rotundity; besides, the edge of this imaging takes on lubricity and acumination. The signal of T1WI was low, and T2WI was high. The capsule wall thickness is uniformity. The signal of T2WI takes on low and ascus nultilocularis leuckart are the character of it. Evaluation of hepatic alveolar echinococcosis takes on anomaly solid bump, T1WI and T2WI all take on low signal, especially, and the low signal of T2WI is the character of it. Use technology of MRH and MRA, the imperceptibility structure of the hepatic echinococcosis nidi, and the relationship of nidi and biliary passage, and the relationship of nidi and blood vessel can be displayed clearly. Conclusion: MRI can examine hydatid of liver parasitism locus, class, bulk, and the relationship betueen contiguity organ, also can classify the different pathology change, and diagnose the space occupying lesion of nay-easy rider of liver.
