Diffuse Homogeneous Bone Marrow Uptake of FDG in Patients With Acute Lymphoblastic LeukemiaSu, Kanae MD; Nakamoto, Yuji MD, PhD; Nakatani, Koya MD; Kurihara, Kensuke MD; Hayakawa, Nobuyuki MD; Togashi, Kaori MD, PhDClinical Nuclear Medicine: January 2013 - Volume 38 - Issue 1 - p e33–e34 doi: 10.1097/RLU.0b013e3182485277 Interesting Images Abstract Author Information PET (positron emission tomography) using FDG (18F-fluorodeoxyglucose) has been widely used in the evaluation of various malignancies, but its clinical application to leukemia remains limited. We report a case of leukemia in which diffuse bone marrow uptake of FDG was observed, and bone marrow aspiration subsequently revealed acute lymphoblastic leukemia. It is not easy to differentiate between physiological and pathologic uptake when diffuse homogeneous uptake in bone marrow is observed.
