While absolute quantification in 18F-FDG PET (Positon Emission Tomography) is widely used in clinical routine, absolute quantification in SPECT (Single Photon Emission Computed Tomography) is under development and its clinical interest remains to be demonstrated. Recent studies carried out on bone scan recordings show the potential interest of quantification indexes such as SUV (Standard Uptake Value).
In oncology, bone scan studies have reported significantly higher SUV values for secondary bone lesions compared with benign osteoarticular lesions , and some have even defined an SUVmax threshold value that points to prostatic bone metastases.
Central Hospital, Nancy, France is the lead sponsor of 778 studies on the registry; 183 are open to participants now.
