Abstract:
ObjectiveTo evaluate the characteristics of MRI of common hepatic lesions by using measurement of T1,T2 and ADC on the MRI and DWI. MethodsMRI and DWI were obtained in 100 patients with common hepatic lesions, and T1,T2,ADCs and the ratios of the ADC of lesion/liver were estimated. (Results)Average T1,T2 and ADCs of hepatic lesions were as follows: hepatocellular carcinoma, (843.92167.75) ms , (73.9014.21) ms and(0.990.26)10~(-3)mm~2/s respectively; hepatic (metastasis), (946.89186.13) ms, (76.3919.76) ms and(1.170.32)10~(-3)mm~2/s (respectively); hepatic cavernous hemangioma, (1102.33213.12)ms, (142.3228.51) ms and (1.810.42)10~(-3)mm~2/s respectively; hepatic cyst, (1516.32617.84)ms ,(247.33112.52)ms and (3.110.38)10~(-3)mm~2/s respectively. The ratio of the ADC of lesion/liver:(hepatocellular) carcinoma was 0.890.17, and significantly lower than the ratio of hepatic metastases((1.27)0.21, P
