磁共振水成像技术在包虫病诊断中的应用

Clinic application of magnetic resonance hydrography on hydatid disease diagnosis

目的:探讨磁共振水成像(MRH)技术在包虫病诊断中的作用,以利于临床手术方案的制定和预后的评估。方法:69例包虫病患者中47例为细粒棘球蚴病,22例为泡状棘球蚴病,69例均行常规MR和MRH检查。结果:47例细粒棘球蚴病中31例为单囊,MRH显示更清晰,16例为多子囊,12例多子囊的110个子囊中,MR普通检查检出率为56.36%,MR水成像检出率为98.18%。MR水成像检出的病灶明显多于MR普通检查检出的病灶。16例泡状棘球蚴病中MR普通检查共发现68个病灶,磁共振水成像技术共发现123个病灶。结论:MRH 结合常规磁共振检查可显示包虫病自身的精细结构,并可获得更多包虫病与临近结构关系的信息,二者结合在包虫病的诊断方面具有许多优势,尤其是对合并并发症的复杂类型的包虫病的诊断。

Objective： To investigate clinic application of magnetic resonance hydrography（MRH） on hydatid disease, so as to it can help the clinic make the treatment plan and prognosis evaluation. Methods： Sixtynine cases with hydatid disease were involved in this study （All cases were proved by surgery and pathology）. Among them, 47 cases were echinococcus granulosus （Eg） and 22 cases were cystic enchinococcosis （Em）. All cases were examed by MRI and MRH. Results： Thirth-one of 47 cases Em were simple hydatid cyst, 16 cases Em were multiple hydatid cyst. Many small lesions can be found in MRH, 62 lesions were found in conventional MRI exam, 108 lesions in MRH. Detectable rate of MRI was 56.36%, and MRH was 98.18%, Detectable rate of MRH was super than that of MRI. In the 16 cases Eg, 68 lesions were found in the conventional MRI; 123 lesions （include many small cystic alveolar） on the MRH. Conclusions： MRH can display more subtle anatomic structure of hydatid itself, including small daughter-cysts of mation on aspect of displaying the hydatid involved adjacent structure, such as ureter, biliary tract and ventricle of brain. MRI combine with MRH has more advantages in dignosis of hydatid, especially it is best for the complicated type of hydatid disease.
