Abstract Objective: To compare the value of Gd-EOB-DTPA enhanced MRI with hepatospecific phase with that of Gd-EOB-DTPA enhanced MRI without hepatospecific phase and contrast-enhanced MDCT in diagnosis of focal liver lesions(FLL). Methods: Thirty-eight patients with 55 FLLs underwent MDCT and Gd-EOB-DTPA enhanced MRI. FLLs were verified based on pathological or follow-up results. CT and MR images were independently analyzed by four radiologists on an ordinal 6-point-scale. Results: Compared to MDCT and MRI without hepatospecific phase, more FLLs were correctly classified into benign and malignant entities by each of the four radiologists on MRI with hepatospecific phase. MDCT achieved sensitivity of 51.6%, specificity of 56.5%, and diagnostic accuracy of 53.6%; MRI without hepatospecific phase achieved sensitivity of 68.8%, specificity of 59.8%, and diagnostic accuracy of 65.0%; MRI with hepatospecific pahse achieved higher sensitivity (89.1%), specificity(78.3%) and accuracy(84.5%) compared to MDCT and MRI without hepatospecific phase(P<0.05). Conclusion: Gd-EOB-DTPA enhanced MRI with hepatospecific phase provides significantly higher diagnostic efficacy compared to MDCT and Gd-EOB-DTPA enhanced MRI without hepatospecific phase in diagnosis of FLLs.
