【摘要】 目的　分析肝包虫病的MRI表现 ,评价MRI对肝包虫病的诊断价值。资料与方法　回顾分析 18例经MRI诊断及手术病理证实的肝包虫病影像学资料。结果　 18例共发现肝包虫囊肿 2 9个。单房型包虫囊肿 6个 ,MRI表现为边缘光滑的圆形或类圆形病灶 ,T1WI呈均匀低信号 ,T2 WI呈高信号 ,囊壁可清晰显示为低信号 ;多房型包虫囊肿 2 2个 ,包虫囊肿内可见多个子囊和不同程度的基质 ,整个囊肿形态呈车轮状或桑葚状 ;实质钙化型包虫囊肿 1个。MRI术前诊断准确性为 94 .4 %。结论　MRI对肝包虫病有较高的诊断价值 ,可作为CT及B超等影像学检查方法的有效补充。更多还原

【Abstract】 Objective To analyze MRI features of hepatic hydatid cyst, to evaluate MRI in its diagnosis.Materials and Methods MRI findings in 18 cases with pathologically proved hepatic hydatid cyst were retrospectively analyzed. Results A total of 29 lesions was found in 18 patients. Six lesions were of unilocular simple cyst type, which displayed as round or oval well-defined lesion, presenting homogeneous low signal on T 1WI and high signal on T 2WI. The cyst wall was demonstrated as low signal. Twenty-two lesions were of multilocular type with the shape of mulberry, within which daughter cysts could be seen. Solid calcified type was seen in one lesion. Preoperative diagnostic accuracy of MRI was 94.4%.Conclusion MRI is of high value for the diagnosis of hepatic hydatid cyst. It should be regarded as an effective supplement to CT and sonography.更多还原
