Table 4 Reported sensitivity, specificity, PVP, NPV and accuracy of multiphase sCT, Gd-BOPTA-enhanced MR and unenhanced MR studies in the characterization of hemangiomas divided into three groups according to size of diameter: small, large and all lesions.

From: Is hepatotropic contrast enhanced MR a more effective method in differential diagnosis of hemangioma than multi-phase CT and unenhanced MR?
