Computed tomographic angiography was performed on nine normal Holstein calves in a crossover method to investigate the effect of a saline chaser for enhancement of the maxillary arteries and dorsal sagittal sinus. One group was administered a contrast injection (600 mg iodine/kg at 4 ml/s) followed by 50 ml of a saline chaser at the same rate as the contrast material. The second group was administered a contrast injection without a saline chaser. Addition of the saline chaser to the contrast material resulted in a higher peak attenuation in the maxillary artery (244.45 ± 36.19 v 202.20 ± 27.07, P<0.05) and dorsal sagittal sinus (241.2 ± 31.51 v 198.88 ± 21.09, P<0.05). These results indicate that a contrast injection followed by saline chaser increased uptake in contrast‐enhanced CT.
