Observational study in Pituitary, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo assess the clinical value of [18F]fluoroethyl-L-tyrosine PET ([18F]FET-PET) correlated with MRI in patients with functioning pituitary adenoma (FPA) with negative or equivocal conventional MRIs during diagnosis, persistent disease and recurrence.
methodsRetrospective observational cohort study of 34 patients with FPAs who underwent a total of 37 [18F]FET-PETs (Cushing’s disease: n = 19, acromegaly: n = 14, prolactinoma: n = 3, and TSH producing adenoma: n = 1) between January 2022 and April 2025. The clinical performance was assessed in the surgically treated cohort, using confirmative histopathology and/or postoperative remission as reference standard.
results[18F]FET-PET identified a single lesion in 28 scans (76%), two lesions in 1 scan (3%), and no lesion in 8 scans (22%). [18F]FET-PET and MRI were concordant positive in 14/37 scans, concordant negative in 1/37, discordant MRI+/[18F]FET-PET + different location in 2/37, discordant MRI-/[18F]FET-PET + in 8/37, discordant MRI+/[18F]FET-PET- in 7/37 and partly concordant in 5/37 scans. In 14 cases surgery resulted in confirmative histopathology and/or postoperative remission, 12 of those had a positive [18F]FET-PET. In 6 cases surgery did not result in confirmative histopathology and/or postoperative remission, of whom 5 had a positive [18F]FET-PET. Overall, the sensitivity was 86% and the positive predictive value 71%. In three patients with acromegaly, [18F]FET-PET was able to localize a lesion, despite biochemical control under continued somatostatin analogue treatment.
conclusion[18F]FET-PET enhances lesion detection and improves personalized treatment in patients with FPA and negative or equivocal conventional MRIs throughout the disease course. Consensus on the timing of [18F]FET-PET with respect to medication and biochemical status is warranted.
