FCH vs FDG PET/CT in Detection of Lesions in Patients With Multiple Myeloma (MIM)

Официальное название

18F-Fluorocholine (FCH) Versus 18F-Fluorodesoxyglucose (FDG) PET/CT in Detection of Lesions in Patients With Multiple Myeloma

Обзор

Hybrid positron emission tomography/computed tomography (PET/CT) has now become available to detect tumors in patients with multiple myeloma. The radioactive glucose 18F-fluorodeoxyglucose (FDG) is the most widely used tracer but findings suggest that PET/CT reveal more lesions when using FCH. In this study, FDG is compared with a more recent metabolic tracer, 18F-fluorocholine (FCH), for the detection of multiple myeloma lesions at time of initial extension assessment. The principal objective of this sudy is to compare the number of suspected hypermetabolic foci of myeloma detected by 18F-fluorocholine PET and by 18F-fluorodeoxyglucose PET during the initial extension assessment.
