Does false-positive 18-fluorodeoxyglucose positron emission tomography-computed tomography ( FDG PET/CT ) scan mimicking malignancies?
The integration of clinical history, morphologic findings of lesions on the CT component, and metabolic activities of PET/CT scan can help reduce false interpretations. Interventional procedures may be needed for tissue confirmation for differential diagnosis.
DSAT and SSAT FA unsaturation shows distinct associations with obesity and IMCL in MZ twins, reflecting compartment-specific metabolic activities. The FA unsaturation in the DSAT depot associates inversely with IMCL content, which raises the possibility of cross talk between the DSAT depot and the rapid turnover IMCL depot.
