Diagnostic Feasibility of Cardiac PET CT in the Evaluation of Inflammatory, Infectious, and Malignant Heart Disease.

Cardiac Positron Emission Tomography (PET) is a power- ful imaging tool with diverse applications in the detection and diagnosis of various cardiac conditions, including inflammatory, infectious, and neoplastic processes. Using the radiotracer 18F-fluorodeoxyglucose (18F-FDG), cardiac PET enables the identification of cardiac involvement in diseases such as sarcoidosis and severe infections affecting the heart tissue. Additionally, 18F-FDG PET is valuable in the evaluation of cardiac masses, helping to assess their metabolic activity and potential malignancy. As a non-invasive imaging modality, 18F-FDG PET provides crucial insights into the pathophysiology of cardiac diseases, aiding in early diagnosis, therapeutic decision-making, and monitoring of treatment response.
