Abstract：Objective: To evaluate the efficacy of DWI for diagnosis and differentiation of common liver masses. Methods: DWI was performed in 88 patients having hepatic lesions, including primary hepatic carcinoma(n=28), hepatic metastases(n=15), hepatic cavemous hemangioma(n=33) and hepatic cyst (n=12). The apparent diffusion coefficient(ADC) values of these lesions were measured, then statistical analysis was performed. Multiphase dynamic enhancement was performed to observe dynamic contrast-enhanced changes in arterial, portal and delay phase of these lesions. Result: The ADC values of hepatic cysts and hemangiomas were higher than those of primary hepatic carcinomas and hepatic metastasis, which were significantly different(P＜0.01). According to signal intensity in arterial phase, hepatic malignant tumors were classified into hypervascular and hypovascular lesions. Conclusion: The measurement of ADC values is helpful in MR diagnosis and differentiation of common liver masses.
