The artifacts of standard uptake value (SUV) on FDG PET/CT in different clinical setting

Learning Objectives 1. Highlight the importance of SUV errors identification in FDG PET/CT imaging. 2. How to check the validity of the SUV result in FDG PET/CT studies. 3. Describe the different origins of the errors and the protocols to prevent SUV errors. 4. The educational review will help to provide a more reliable qualitative and quantitative interpretation of FDG PET/CT imaging.

The imaging and the SUV values presented in front of you may not be the correct imaging with corrected SUVs. FDG PET/CT is often associated with SUV values errors and artifacts. If un-identified, these artifacts may lead to false positive, false negative interpretations and inaccurate quantitative data. It is extremely important for the PET/CT physician to become familiar with them so that they can be easily recognized, corrected and more importantly prevented.
