Accumulation of C-methionine in the normal pituitary gland on C-methionine PET.

Background For pituitary tumors, positron emission tomography (PET) with C-methonine (MET) has been reported as feasible to facilitate diagnosis. MET is well-known to accumulate in the normal pituitary glands, but almost no studies have examined the degree of MET accumulation in the normal pituitary gland. Purpose To investigate accumulation of MET in normal pituitary gland on PET/CT.
