SUVs need adjusting for high-resolution PET/CT

By Wayne Forrest

Radiologists and clinicians working with high-resolution PET/CT should adjust standardized uptake values (SUVs) accordingly to reduce the chance of errors in classifying head and neck tumors, according to researchers from the University of Minnesota in Minneapolis. In a recent study, the team found that maximum SUVs for head and neck lesions are significantly higher with high-resolution PET/CT than with conventional or lower-resolution systems.

Radiosurgery has gained popularity as a way to manage TN, but will it become the gold standard treatment? Neurosurgeons who work with radiosurgery praise it as being faster, safer, and just as effective as traditional management methods.
