Outline of Final Research Achievements |
We established a method for semi-automatic and quantitative measurement of activity of glucose metabolism in the myocardial inflammation using FDG-PET. Evaluation of steroid treatment effect by quantitative metabolic volume (MV) revealed that 1 month of steroid treatment markedly reduced myocardial inflammation, but cardiac function improvement was not observed. Patients presenting with the acute phase of AV block are related to FDG accumulation rather than MRI delayed contrast images and may be associated with the activity of inflammation. Detailed assessment between changes in electrocardiogram findings after treatment and image inspection including FDG PET, MRI and sympathetic function is required in the future.
