Establishing local diagnostic reference levels for adult whole-body PET/CT in Malaysia.

Background: The combination of positron emission tomography (PET) and computed tomography (CT) scanning has significantly transformed the field of nuclear medicine.

Purpose: This study aims to establish local diagnostic reference levels (LDRLs) for adult positron emission tomography/computed tomography (PET/CT) scans utilizing three radiotracers:18F-fluorodeoxyglucose (18F-FDG), 68Gallium-prostate-specific-membrane-antigen (68Ga-PSMA), and 68Gallium-etraazacyclododecane-tetraacetic-acid-octreotide (68Ga-DOTATATE).

Methods: Demographic data, radiation dose information, scanner PET/CT system specifications, and acquisition protocols were collected from the Department of Nuclear Medicine at Penang Hospital in Malaysia.
