摘要
目的:探讨肝脏血管周围间隙增宽的MRI表现及临床价值。方法:回顾性分析17例肝内血管周围间隙增宽患者的MRI及临床资料,观察其影像学表现,总结分布特点、发病机制及疾病类型。结果:肝脏血管周围间隙增宽表现为门静脉左右支及其分支周围T1WI低信号,T2WI高信号,呈"轨道征"或"晕环征"。17例血管周围间隙增宽中肝源性12例(慢性活动性肝炎7例,肝硬化4例,外伤1例),胆源性2例,心源性2例,胃癌淋巴结转移1例。结论:MRI可以准确显示肝脏血管周围间隙增宽的影像表现及其分布特点。
Objective： To investigate the displaying of MRI and its significance in the diagnosisof intrahepatic periportal space enlargement. Methods： The MRI images and clinical data of intrahepaticperiportal space enlargement in 17 patients were retrospectively analyzed, to concluse theMRI feature,the distribution characteristics,the pathogenesis of intrahepatic periportal space enlargement,and the disease types. Results： Long T1 Long T2 signal was found around the left andright potal vein and branches in portal phase in T1WI and T2WI series, called ＇dual-track＇ or ＇solarhalo＇. Of those 17 cases,12 cases were originated from hepatogenic, including 7cases of chronicactive hepatitis, 4 cases of hepatocir-rhosis, 2 cases of trauma; 2 cases were Originated frombiliary,1 cases of cardiogenic, 1 cases of malignant lymphadenopathy from cancer of the stomach. Con-clusion： MRI can accurately demonstrate the imaging characteristics and distribution pattern of intrahepaticperiportal space enlargement, which is helpful for the therapy.
