18F-FDG Tumor Imaging Radiotracer Radiation Doses

 

 

 

 

 

 

 

 

            The table shows the radiation absorved doses of most important tissues for 18F-FDG, expressed in Rad or mGray  per mCi or MBq, respectively. It also displays the adult effective dose in terms of Rem or mSv per mCi or MBq, respectively. Note that the critical organ is the bladder. It is important for the patient to keep a normal hydration and void as often as possible. If a total dose of 15 mCi or 555 MBq are injected then the total absorved dose would be of  0,65 Rad or 6,7 mSv, respectively.
