In the past decade, 18F-fluorodeoxyglucose positron emission tomography combined with computed tomography (18F-FDG PET-CT) scans have been increasingly implemented in the diagnostic process of several haemato-oncological conditions. Accurate assessment of bone marrow activity observed on 18F-FDG PET-CT is crucial for a correct diagnostic conclusion, subsequent treatment decision, and follow-up strategies.
By systematically considering the arguments of the level of 18F-FDG uptake, distribution pattern, coinciding changes of the bone structure, and the clinical context, interpretation and validity may improve. This review aims to give a comprehensive overview of the different patterns of 18F-FDG uptake on PET/CT in common benign, clonal, and malignant haematological conditions, accompanied by illustrative cases.
