Abstract:
 The number of installed PET/CT scanners is increasing and this will increase the workload which would result in higher extremity radiation dose. Thus, an effort should be made to review the recent practice of radiation protection in PET/CT imaging in order to reduce the extremity radiation dose.
 The extremity radiation dose in PET/CT is higher than the conventional nuclear medicine practice. The high radiation dose is mainly from the high energy positron emitter radionuclide 18-F which is mainly used to label FDG and producing high-energy annihilation photons. The high extremity radiation dose is mainly occurring during the dispensing and injection of the FDG and during the direct communication with injected patient.
After reviewing the current literature we can see that there are many practical techniques that can be used to significantly reduce the extremity dose. Technical aspects such as:  The relationship between whole body dose and extremity dose, workload and staff rotation, Extremity dose distribution on the hand and fingers and finally, Finger dose on dominant and non-dominant hand will be explained and discussed.
The practical importance of using new technology such as automatic or semi-automatic dispensing/injection systems in reducing extremity dose will be presented with results from our clinical experience.
The aim of this talk is to provide an overview
