Abstract:

Objective To compare the efficacy of susceptibility weighted imaging (SWI) in detection and differentiation of hepatocellular carcinoma and hemangioma. Methods The data of 41 patients with 51 hepatocellular carcinoma lesions and 13 patients with 23 hemangioma lesions during Jan to Feb,2012 were selected.All patients underwent MR including SWI in the study. Two radiologists interpreted SWI images and measured the signal intensity (SI) of the lesions,adjacent liver parenchyma SI and standard deviation (Sd), while the signal noise ratio (SNR) and the contrast noise ratio (CNR) were calculated. The detecting rates of the lesions and the mean SNR and CNR were compared between the two diseases. Results There were no significant difference in the detecting rate of hemangioma and hepatocellular carcinoma by SWI. The SNR and CNR of hemangioma were higher than those of hepatocellular carcinoma on DWI (P<0.05), and there was a significant difference between the two diseases as for the SNR and CNR. Conclusion SWI is valuable in diagnosis and differential diagnosis of hepatocellular carcinoma and hemangioma.
