چکیده
|
A shift to administration of optimal dose of 18f-fdg between 4 and 5 mbq/kg from the current practice of higher doses potentially yields a reasonable-to-excellent pet image. for this purpose, whole-body mip images of 32 patients (23 men, 9 women, age 51.9 ± 13.7 years), administered with 18f-fdg (activity 5.3 ± 0.5 mbq/kg, 45 minutes uptake time) for whole-body pet/ct examinations, were evaluated. image quality was assessed visually by two radiologists using a three-point scoring scale: poor, reasonable and excellent. the interobserver agreement revealed a kappa value higher than 0.7. therefore, the utilisation of 18f-fdg dose between 4 and 5mbq/kg is considered an optimum dose for whole-body pet/ct examination.
