what does SUV max of 8.4 mean? my father had a PETSCAN & the report states a spiculated nodule in the left upper left node of the lung measures 1.4x1.4cm & is intensely FDG avid w/ max SUV of 8.4 This lesion is consistent w/malignancy.There is also a 9x8 prevascular lymph node is moderately FDG avid w/SUV max of 2.8 It is highly suspicious for metastic lymphadenopathy. I am out of state & would like to understand this report more. I know it is not good, but if someone could explain this in lamin terms, i would appreciate it very much.
SUVmax (standardized uptake value) is a measure for the maximum uptake of radiolabelled glucose when performing a PET with radiolabelled glucose.
The higher the value, the higher the metabolic activity of cells/tissue. Nodules that show high metabolic activity are more likely to be cancer.
