摘　　要：目的探讨磁共振灌注成像对不典型肝脓肿的诊断价值。方法对临床或手术病理证实的8例不典型肝脓肿的MRI资料进行回顾性分析。结果不典型肝脓肿MRI多表现为不均匀的稍长T1、稍长T2信号,时间-信号曲线表现为"速升-缓升"样变化。结论不典型肝脓肿多为早期肝脓肿,MRI平扫无特征性,结合灌注成像有助于诊断和鉴别诊断。Objective To evaluate the diagnostic value of MR perfusion imaging in atypical hepatic abscess .Methods MRI data of 8 cases with atypical hepatic abscess proved by pathology and follow-up after clinical therapy were retrospectively analyzed . Results The atypical hepatic abscess appeared almostly as the uneven slightly signal intensity on T1WI and the uneven slightly high signal intensity on T2WI , the time signal curve appeared as the type of quickly rise or slowly rise . Conclusion Most of the atypical hepatic abscess is early hepatic abscess,MRI showed nonspecific features,in combination with MR perfusion weighted imaging can improve the diagnosis and differential diagnosis of the atypical hepatic abscess .
