[Abstract] Objective: To compare the efficacy of DWI and BLADE-T2-SPAIR in detection of focal liver lesions.Materials and Methods: Thirty-five patients with 51 focal hepatic lesions (31 malignant and 20 benign) were included in the study. Both BLADE-T2-SPAIR and DWI were performed on each patient. One radiologist interpreted BLADE-T2-SPAIR and DWI images and measured the signal intensity (SI) of the lesions and adjacent liver parenchyma on BLADE-T2-SPAIR and DWI, and the contrast ratios (CR, the ratio of SI of lesion/liver) were calculated. The detecting rates of the lesions and the mean CRs were compared between the two sequences.Results: There were no significant difference in the detecting rate of cyst, hemangioma, metastatic tumor by BLADE-T2-SPAIR and DWI, the detecting rates of hepatocellular carcinoma (HCC) by BLADE-T2-SPAIR were higher (P<0.05) than those by DWI. CR was calculated for all lesions. The CRs of cyst on BLADE-T2-SPAIR were higher than those on DWI (P<0.05), and no significant differences were found between the two sequences as for the CRs of hemangioma, HCC, metastatic tumor.Conclusions: DWI is not superior to T2WI in detection of HCC.
