U.S., Jan. 23 -- ClinicalTrials.gov registry received information related to the study (NCT07360548) titled 'Study of 18FET PET in Functional Pituitary Adenomas With Indeterminate MRI Findings' on Dec. 10, 2025.

Brief Summary: Pituitary adenomas (PAs) are common benign tumors, but their potential for tumor aggression and hormone secretion make them serious tumors. In particular, patients with secreting tumors [prolactinomas (prolactin secretion), acromegaly (growth hormone), Cushing's disease (ACTH), thyrotropic adenomas (TSH)] have increased morbidity and mortality. They may be small and/or undetectable by magnetic resonance imaging (MRI), the current gold standard for morphological evaluation of pituitary lesions. The diagnosis of recurr...
