Objectives: Increased 18F Fluoro-2-deoxyglucose (FDG) uptake in the myocardium is frequently observed while performing whole body oncologic PET CT scans. Our objective in this presentation is to pictorially highlight the spectrum of FDG avid findings in myocardium and to provide an accurate PET/CT interpretation to minimize false positive diagnosis.
Methods: We studied the normal variations and abnormal appearances of myocardial FDG uptake in routine oncologic FDG PET scans retrospectively over a period of 1 year and correlated the findings with clinical follow up as well as with the literature.
Results: Most illustrative images were selected to present the categories of normal and abnormal findings encompassing the physiological variants (uptake in the atrial wall, ventricle wall, atrial fibrillation, papillary muscle, lipomatous hypertrophy of the interatrial septum, etc), post-surgical changes, atherosclerotic changes, myopathies, infection/ inflammation, benign lesions, neoplasms and malignant infiltrations.
Conclusion: Knowledge about the myocardial glucose metabolism, variation in normal uptake pattern and specific abnormalities is indispensable and essential in the interpretation of myocardial FDG uptake. The presented PET CT case based pictorial review raises awareness and strengthens the judgement of the reading physician.
