Although 18F-FDG is the dominant radiotracer for PET imaging of hematological malignancies, radiolabeled amino acids have also been investigated to improve image quality in areas of high 18F-FDG uptake such as the central nervous system. We present a case of a 57-year-old woman who underwent an 18F-FDOPA scan for primary CNS lymphoma, which demonstrated an unexpected false-positive uptake in the right frontal lobe, due to a developmental venous anomaly.

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...
