Value of CT and MRI to the diagnosis of hepatic lobe infarction

目的探讨CT及MRI在肝叶型肝梗死诊断中的应用价值。方法回顾性分析6例肝叶型肝梗死患者的CT和/或MRI影像学资料。结果 CT和/或MRI显示病灶均呈楔形,沿肝脏边缘分布、尖端指向肝门,其内血管影走行自然、部分稍变细;CT平扫显示病灶呈低密度;MRI平扫显示T1WI呈低信号,T2WI呈高信号。结论 CT及MRI对肝叶型肝梗死均有重要诊断价值。

Objective To explore the application value of CT and MRI to the diagnosis of the liver lobe infarction. Methods The CT and /or MRI findings of hepatic lobe infarction were retrospectively analyzed in 6 cases. Results The images of the lesions were all wedge shaped, and located along the edge of the liver, with the tip pointing to the hepatic portal. The inner vessels arranged well and some of which were found slightly thinner. CT scan showed low intensity, and MRI scan showed low signal intensity on T1WI and high signal intensity on T2WI. Conclusions CT and MRI play important roles in the diagnosis of hepatic lobe infarction.
