Abstract
Objective To evaluate the diagnostic value of MR imaging in hepatic focal nodular hyperplasia( FNH). Methods ten cases with 26 lesions, which were confirmed with the biopsy pathology of puncture or surgery ,were included in the First Hospital of Qiqihaer city from January 2008 to April 2010. The MR images of 10 cases were investigated retrospectively by 3 experienced physicians. Results Twenty-three lesions showed isointense/slight hypointense and 3 lesions of hyperintense on T1WI. Twenty-three lesions were slight-hyperintense, 1 lesion of isointense and 2 lesions of hypointense on T2WI. Five lesions showed heterogenously strong enhancement and 19 lesions , homogenously strong enhancement during arterial phase after injection of Gd-DTPA,and 13 lesions of slight hyperintense and 11 lesions of isointense or hypointense during portal venous and delayed phase. Central scar was detected in 11 lesions ,which was hypointense on T1 WI and hypointense to hyperintense on T1WI. two cases showed no enhancement during arterial phase, portalvenous phase and delayed phase. Eight cases were diagnosed correctly, 1 case was diagnosed as benign focus ( characteristically difficult) , 1 case was mistaken as malignant tumor. Conclusions The MR imaging findings of FNH are specific and it is possible that most of FNH can be diagnosed combining case history.关键词
