MRI of hepatic adenomatosis: initial observations with gadoxetic acid contrast agent in three patients.

OBJECTIVE: The purpose of our study was to describe the MR signal characteristics of histologically proven liver adenomatosis in three patients using gadoxetic acid, a newly developed liver-specific MR contrast agent.

CONCLUSION: In all three patients, more than 100 liver adenomas revealed no metabolism of the new liver-specific contrast agent in the delayed phase. Because of absent or strongly reduced intracellular uptake of gadoxetic acid in all adenomas during delayed contrast-enhanced series, differentiation of adenomas from dysplastic or malignant lesions was not possible.
