1. To illustrate the pattern of various hepatic lesions with paradoxical uptake or unusual defect of the gadoxetic acid in HBP of liver MRI 2. To discuss how to use this knowledge of unusual pattern of Gd-EOB-DTPA for differential diagnosis of various hepatic lesions  

1. Introduction 2. Typical and atypical imaging features of hepatic nodules in Gd-EOB-DTPA-enhanced MRI 1) Hepatocellular carcinoma 2) Metastasis from colon, breast, stomach, pancreas, etc 3) Cholangiocarcinoma 4) Focal nodular hyperplasia 5) Hepatic adenoma 6) Abscess 7) Eosinophilic infiltrations 3. Pattern analysis according to Gd-EOB-DTPA uptake 4. Summary and benefit of these imaging features of various hepatic lesions for differential diagnosis in clinical practice.  Summary 1. Paradoxical uptake within hepatic lesions is not unusual finding on HBP of gadoxetic acid enhanced 3T MRI 2. The malignant nodule may not show a total defect on HBPof gadoxetic acid enhanced 3T MRI 3. FNH may show defect on HBP 4. Hepatic adenoma may also contrast uptake on HBP 5. The uptake pattern include total, peripheral, mixed, and target appearances 6. A pattern approach based image analysis may aid in making either a specific diagnosis or narrowing differential diagnosis of various hepatic lesions
