A Pilot Study Evaluating the Potential of 18F Fluorodeoxyglucose PET-CT Imaging in Diagnosing Cardiac Rejection.

This pilot study aims to assess whether 18F-FDG PET CT imaging has the potential in diagnosing cardiac rejection. The investigators aim to recruit 20 heart transplant subjects within two groups of 10 subjects each. One group will have participants with definite rejection and the other group will have participants with definite no rejection. Subjects will be placed into study groups based on their heart muscle biopsy, echocardiogram, clinical symptoms, ECG, and presence or absence of donor specific antibodies. Each group will then undertake a 18F-FDG PET CT scan to identify whether this imaging modality has a role in identifying cardiac rejection. The study subjects and the research team will be blinded to the results of the PET CT until the end of the study.
