title: Fluorocholine PET/computed tomography: physiologic uptake, benign findings, and pitfalls.
abstract: Choline PET has a role in the diagnosis of malignancies. Knowledge of normal biodistribution plays a vital role in disease characterization and in differentiating normal variants from disease processes. CT and MR scans provide complementary information, and choline-positive sites should be correlated clinically to exclude inflammatory disorders.
