Abstract:

 


Objectives:
18Fluorine-fluorodeoxyglucose (18F-FDG)
positron emission tomography/ computed tomography (PET/CT) is commonly used for
diagnosis, staging and re-staging of cancers and for determining the
effectiveness of treatment. Because of renal, ureteral and urinary involvement
of 18F-FDG radiopharmaceutical after its injection, patients
subject to radioactivity during its effective half-life. The aim of the present
study was to determine the degree of association between effective dose levels
of patients and bladder emptying of patients having PET/CT scans. 


Methods: The present retrospective
study included 108 patients
(43 females and 65 males, average age: 60.9 ± 12.7 years). Effective dose level
as mSv/h was determined from a distance of 1 m in all patients before and after
bladder emptying at the first hour following 18F-FDG injection.
Radioactivity excretion amounts were compared based on gender, age, body mass
index, fasting blood sugar level and clinical diagnosis. 


Results: Amount of radioactivity decreased by 22.75% ± 14.77%
after bladder emptying. No association was found between urinary excretion
level and age, gender, fasting blood sugar and body mass index (p > 0.05). 


Conclusions: Active
emptying of bladder in patients having PET/CT scans where 18F-FDG
radiopharmaceutical is involved is an effective method for the radiation safety
of both health workers and patients.
