  • Title: Scintigraphic validation of a magnetic resonance imaging method to study gastric emptying of a solid meal in humans.
    Author: Feinle C, Kunz P, Boesiger P, Fried M, Schwizer W.
    Journal: Gut; 1999 Jan; 44(1):106-11. PubMed ID: 9862835.
    Abstract:
    BACKGROUND: We have previously used a magnetic resonance imaging (MRI) method to study gastric emptying of liquids. So far, however, it has not possible to assess solid gastric emptying with this technique. AIMS: To validate scintigraphically MRI as a method for measuring emptying of a mixed solid/liquid meal. METHODS: In eight healthy subjects, gastric emptying of a solid/liquid (SM) and a liquid meal (LM) of identical energy content and macronutrient composition was studied by scintigraphy and MRI for 120 minutes. RESULTS: MRI and scintigraphy agreed with respect to emptying profiles (intraclass correlation coefficient (RI) SM: 0.988, RI, LM: 0.917), t1/2 (SMMRI: 129 (9), SMScinti: 123 (11) minutes, NS; LMMRI: 100 (7), LMScinti: 110 (8) minutes, NS) and AUC (SMMRI: 8999 (232), SMScinti: 8788 (277) min%, NS; LMMRI: 8819 (368), LMScinti: 8891 (321) min%, NS). CONCLUSIONS: MRI can be used to measure reliably gastric emptying not only of liquid but also of mixed solid/liquid meals in humans.
