MR imaging during arterial-portography (MR-AP) in the detection of hepatic tumor: comparison with CT-AP.

This study was undertaken to compare the detection rate of hepatic space occupying lesion (SOL)s between computed tomography during arterial portography (CT-AP) and magnetic resonance imaging during arterial portography (MR-AP) and the differences in time intensity curve on MR-AP between HCC, metastatic tumor, FNH, and hemangioma. We performed CT-AP and MR-AP in 17 patients including 14 cases of HCC and one each of metastasis, FNH, and hemangioma. MR-AP was performed by Turbo-FLASH sequence. There was no statistically significant difference between CT-AP and MR-AP in detecting satellite lesions in terms of smallest diameter and number of flow defects (p > 0.05). Hemangioma showed rapid enhancement after the first pass and, consequently, the same enhancement as the hepatic parenchyma. MR-AP was comparable to CT-AP in the detection of hepatic SOLs. Hemangioma showed an enhancement pattern different from those of HCC, metastatic tumor, and FNH, which showed patterns similar to each other.[1]
