Does 18F-FDG and 82Rb PET imaging detect abnormal myocardial inflammation in a patient with cardiac Chagas disease?
18F-FDG and 82Rb PET imaging can detect active myocardial inflammation in cardiac Chagas disease, aiding in its diagnosis and evaluation.

Supports PET evaluation of myocardial inflammation in Chagas disease; leaves open clinical adoption pending prospective studies.
Uptake of the radiopharmaceutical F-FDG visualized by PET imaging can reflect abnormal myocardial inflammation. When utilized in conjunction with other imaging modalities, such as echocardiography, PET F-FDG imaging can help distinguish between active cardiac sarcoidosis and other etiologies of nonischemic cardiomyopathy. We present a case of a 46-year-old man with nonischemic cardiomyopathy and ventricular tachycardia who underwent an echocardiogram suggestive of cardiac Chagas disease. A subsequent F-FDG PET demonstrated abnormal hypermetabolism. The diagnosis was confirmed by positive serologic examination results.
