NCT ID: NCT04437927 Completed - Clinical trials for Myocardial Inflammation

Impact of 100mL Lipid Emulsion for Intravenous for Suppression of Myocardial Glucose Metabolism in 18F-FDG PET/CT

Start date: April 7, 2020
Phase:
Study type: Observational [Patient Registry]

There is increasing evidence that [18F]-2-fluoro-2-deoxy-D-glucose (18F-FDG) PET/CT is useful in the identification and treatment of disease processes that involve cardiac inflammation and infection. Current applications include imaging intra-cardiac device and prosthetic valve infections, evaluating patients with known or suspected cardiac sarcoidosis or other inflammatory cardiomyopathies. However, because normal myocardium can metabolize both glucose and free fatty acids (FFAs), physiological accumulation of FDG in the myocardium can interfere with the recognition of abnormal FDG uptake. The use of a low-carbohydrate diet with a prolonged fast ≥ 12 h nutrition followed by a fast of at least four hours is the effective preparation recommended to suppress physiological myocardial FDG uptake. However, the rate of suppression of physiological accumulation of FDG with this method in our center is only 50%.
