Early subphases of enhancement. The early hepatic arterial phase (EHAP) was observed on transverse 2D-GE images (a, b) acquired on 1.5 T. The mid hepatic arterial phase (MHAP) was observed on transverse 3D-GE images (c, d) acquired on 3.0 T. The contrast enhancement is seen in the aorta, renal arteries and superior mesenteric artery, but there is no contrast enhancement in the veins on both EHAP and MHAP. The renal cortex, spleen, pancreas and liver demonstrate slight enhancement on EHAP. The renal cortex, spleen and pancreas show mild enhancement and the liver shows slight enhancement on MHAP. The minimal enhancement of the normal pancreas (arrow d) reflects the too early acquisition of data in these subphases.
