Abstract. Background: The purpose of this study was to evaluate the effect of portal flow augmentation on hepatic computed tomographic (CT) enhancement. Methods: Thirteen patients undergoing follow-up CT of the liver within 6 months of initial study ingested 470 mL of Ensure® 30 min before the second examination. Contrast medium injection and scanning parameters were identical for both studies. Results: The time to peak and the maximum and mean liver enhancements were 68 s, 56 HU, and 46 HU, respectively, for the examinations without Ensure® and 68 s, 53 HU, and 44 HU for the examinations with Ensure®. No significant difference was found between the two groups when mean liver enhancement was calculated over 3-s time intervals. Conclusion: Portal venous flow augmentation induced by a meal had no effect on liver enhancement.
