Abstract 【Objective】To discuss the value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI),diffusion-weighted imaging(DWI),and multislice spiral CT(MSCT) enhancement scanning in the differential diagnosis of hepatic hemangioma and liver metastatic carcinoma. 【Methods】 Thirty-eight patients with liver metastatic carcinoma were enrolled in the metastasis group,and thirty-two patients with hepatic hemangioma were recruited in the hemangioma group. All patients received examination of DCE-MRI,DWI,and MSCT before surgery. According to pathology diagnosis as gold standard,the imaging characteristics of the two groups were compared,and diagnostic value of indicators were calculated by drawing 2×2 contingency tables for each type of examination. 【Results】The proportion of patients in the hemangioma group with arterial enhancement and portal venous enhancement was significantly lower than that in the metastasis group,and the proportion of patients in the hemangioma group with high signal in the delay phase was significantly higher than that in the metastasis group(P<0.05). The ADC value of DWI in the hemangioma group were significantly higher than that in the metastasis group(P<0.05). Preoperative MSCT examination showed that the mean transit time,liver blood volume,and capillary surface permeability measurements of the hemangioma group were higher than those of the metastasis group(P<0.05),while lesion arterial perfusion and liver blood flow measurements in the hemangioma group were lower than those in the metastasis group(P<0.05). The sensitivity and specificity of DCE-MRI for differentiating liver metastatic carcinoma and hemangioma were 76.32% and 87.50%,respectively; The sensitivity and specificity of DWI were 78.95% and 90.63%,respectively; And the sensitivity and specificity of MSCT were 71.05% and 93.75%,respectively. The sensitivity of the three combined differential diagnosis of liver metastatic carcinoma and hemangioma was 92.11% and the specificity was 87.50%. 【Conclusion】The combined application of DCE-MRI,DWI,and MSCT in the differential diagnosis of liver metastatic carcinoma and hepatic hemangioma can significantly improve sensitivity while maintaining high specificity.
