Fig. 2 Diagram and drawings show timetable during contrast-enhanced CT
examination of 56-year-old woman with early gastric cancer. During a single
breath-hold of 31 sec, venous phase scanning of 8 sec was performed serially
from arterial phase of 8 sec with 15-sec interval. Three-dimensional
angiography images in arterial phase (arteriography [diagram a]) and venous
phase (venography [diagram b]) were individually reconstructed using
volume-rendering technique and were then fused. RGA = right gastric artery,
LGA = left gastric artery, GDA = gastroduodenal artery, RGEA = right
gastroepiploic artery, RGV = right gastric vein, LCV = left gastric coronary
vein, RGEV = right gastroepiploic vein, ARCV = accessory right colic vein, GCT
= Henle's gastrocolic vein, PV = portal vein.
