磁共振平扫及增强扫描对肝包虫病诊断价值∗

摘要

Objective:To observe the magnetic resonance ( MRI) plain and enhanced scan performance of hepatic echinococcosis, to investigate the accuracy of MRI diagnosis of hepatic echinococcosis. Method:A retrospective analysis of 30 cases of hydatid disease of liver in our hospital and confirmed by operation and pathology were chosen as research subjects. The preoperative MRI examination findings and diagnostic posi-tive rate were analyzed. Result:Among the 30 patients, there were 25 patients with cystic echinococcosis, 5 patients with bubble hydatid disease. MRI diagnosis of 29 cases of patients, 24 cases of hydatid disease, 5 cases of hydatid disease bubble, The diagnostic positive rate was 96.7% (29/30).MRI scanning, cyst fluid T1 WI showed low signal, T2 WI showed high signal, MRI scanning, cyst fluid T1 WI showed low signal, T2 WI showed high signal, The cyst wall was slightly higher than that of cyst fluid of T1 WI signal, T2 WI showed relatively low signal, Cyst of liver tissue around the signal without exception, no halo around the cav-ity. Enhanced scanning, only 2 cases cyst walls mild enhancement. Conclusion:The value of MRI in the di-agnosis of hepatic hydatid disease is high, can clearly show the location and signal characteristics of lesions, The higher the positioning, quantitative and qualitative diagnosis, can be used as a supplementary means of diagnosis and treatment of hepatic hydatid cyst.%目的：观察肝包虫病在磁共振( MRI)平扫及增强扫描下的表现,探讨磁共振对肝包虫病的诊断准确率。方法：回顾性分析在我院治疗并且经手术病理证实为肝包虫患者30例,对其术前行MRI检查下表现及诊断阳性率进行分析。结果：在30例患者中,细粒棘球蚴病患者共25例,泡球蚴病患者5例。共发现包虫囊肿53个,病灶大小为1.7~11.7cm,为多房型囊肿42个,单房型囊肿9个。MRI诊断阳性患者29例,其中细粒棘球蚴病24例,泡球蚴病5例,诊断阳性率为96.7%(29/30)。MRI平扫中,囊液T1 WI呈低信号,T2 WI呈高信号,囊壁T1 WI稍高于囊液信号,T2 WI呈相对低信号,囊肿周围肝组织信号无异常,囊腔周围无晕环。增强扫描,仅2例患者包囊囊壁有轻度强化。结论：MRI对肝包虫病诊断价值高,可以清晰显示病变的部位及信号特征,对其定位、定量及定性诊断价值较高,可以作为对肝包虫病的补充诊治手段。
