definition of suv
The blue dot in the MIP image bottom right marks the maximum SUV within the ROI. The standardized uptake value (SUV) is a nuclear medicine term, used in positron emission tomography (PET) as well as in modern calibrated Single Photon Emission Tomography (SPECT) imaging for a (semi)quantitative analysis.
