We present different findings on 18F-FDG PET/CT and 18F-NaF PET/CT images in 2 patients with multiple myeloma. In 1 case, 18F-FDG PET/CT showed intense uptake in the lesions in the axial skeleton where 18F-NaF PET/CT seemed normal. In addition, a sternal lesion showed FDG uptake only in the center but NaF uptake only in the periphery. In another patient, intense NaF accumulation in a dorsal vertebra was noted, but the corresponding FDG uptake was unimpressive. The role of these 2 radioactive tracers in the management of multiple myeloma continues to be defined.

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
