CT angiography and CT arterial portography in evaluation of hepatic adenomas.

Objective: Our goal was to evaluate the contribution of CT arterial portography (CTAP) and CT angiography to accurate determination of disease extent in patients with known hepatic adenomas. Materials and Methods: Imaging results were reviewed in three women with known hepatic adenomas, all of whom had percutaneous biopsy to confirm the diagnosis. Results of CTAP studies in all patients as well as results of CT arteriography in one patient were compared with routine dynamic CT studies in all three and with MRI studies in two. Results: The CTAP and CT arteriography demonstrated multiple additional lesions in all patients as compared with routine dynamic CT and MRI studies
