Current status and future needs for standards of radionuclides used in positron emission tomography.
Positron Emission Tomography (PET) is being increasingly used as a quantitative technique for detecting disease and monitoring patient progress during treatment. To ensure the validity of the quantitative information derived from the imaging data, it is imperative that all radioactivity measurements that are part of the imaging procedure be traceable to national or international standards. This paper reviews the current status of standards for positron emitting radionuclides (e.g., (18)F, (68)Ge/(68)Ga, and (124)I) and suggests needs for future work.
