| Abstract |
Purpose: Gastric emptying scan (GES) is usually acquired up to 2 hours. Our study investigated whether a fraction of meal-retention in the stomach at 120 minutes (FR120) was predicted from the data measured for 90 minutes by using non-linear curve fitting. We aimed at saving the delayed imaging by utilizing mathematical models.
Materials and Methods: Ninety-six patients underwent GES immediately after taking a boiled egg with 74 MBq (2mCi) Tc-99m DTPA. The patients were divided into Group I (T1/2 ≤90 min) and Group II (90 min |
