  		Fig. 1. —65-year-old woman with symptomatic giant hemangioma. CT angiogram shows entire hepatic trunk (arrow) derived from superior mesenteric artery (SMA), which is Michels type IX variant of arterial anatomy [14]. Cloudlike regions of high attenuation are due to enhancement of hemangioma (Hem). Metallic cholecystectomy clips (arrowheads) are present. SA = splenic artery.

  		Fig. 2A. —41-year-old woman with symptomatic giant hemangioma referred for imaging before hepatic resection. MDCT angiogram was interpreted as showing conventional arterial anatomy (Michels type I [14]). Cloudlike regions of high attenuation (arrows) in liver are due to characteristic enhancement pattern of hemangioma (HEM). At surgery, small accessory left lateral segmental artery was found to arise from left gastric artery (LGA). Although left gastric artery can be identified, small accessory left hepatic artery is not visualized. Residual barium (BA) is seen in hepatic flexure of colon. CHA = common hepatic artery, SA = splenic artery.

  		Fig. 2B. —41-year-old woman with symptomatic giant hemangioma referred for imaging before hepatic resection. Two-dimensional axial source image nicely illustrates small accessory left hepatic artery (arrows) passing through fissure for ligamentum venosum.

  		Fig. 3A. —62-year-old woman with metastatic colon cancer to right hepatic lobe. MDCT angiogram shows faint visualization (arrows) of segmental hepatic arterial branches. These branches were considered to be third order. CHA = common hepatic artery, SA = splenic artery.

  		Fig. 3B. —62-year-old woman with metastatic colon cancer to right hepatic lobe. Two-dimensional axial source image shows clear visualization of third- (arrow) and fourth-order (arrowheads) subsegmental branches in hepatic parenchyma.

  		Fig. 4A. —71-year-old woman with metastatic colon cancer to left lateral hepatic segment. On anteroposterior projection of MDCT angiogram, relationship of gastroduodenal artery (GDA) to left (LHA) and right hepatic artery (RHA) is unclear.

  		Fig. 4B. —71-year-old woman with metastatic colon cancer to left lateral hepatic segment. On right posterior oblique MDCT angiogram, GDA (arrowheads) is shown to arise from LHA, distal to takeoff of RHA (arrow). In patient with this arterial anatomy, placement of chemotherapy perfusion catheter into GDA would fail to perfuse right hepatic lobe.
