Comparing two imaging scans for pituitary tumors

This trial is testing whether a newer imaging scan called 18F-fluoroethyltyrosine PET (FET-PET) can give doctors the same helpful information as an older scan called 11C-methionine PET (Met-PET) for diagnosing and monitoring pituitary adenomas—tumors of the pituitary gland. Researchers want to see if the newer scan works just as well, which could make this type of advanced imaging available to more patients. You would have already had one scan as part of your regular care, and this study would add one additional scan for comparison.

Currently, the older imaging scan is the standard way to look closely at pituitary tumors, but it may not be available everywhere. If the newer scan produces similar results, doctors could offer more patients access to this detailed imaging to better diagnose and monitor their condition.
