PHYTO-PET - Imaging plant physiology on a long-axial field-of-view PET scanner.
Article in European journal of nuclear medicine and molecular imaging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimNon-human imaging using either inanimate phantoms or live animal models is sometimes performed as an alternative to human subjects but involve limitations either in fidelity for the former and ethical considerations for the latter. Plant biology has previously been probed using positron emitting tracers, but the potential for long-axial field-of-view (LAFOV) PET/CT systems with higher sensitivities and longer axial coverage in the imaging of plant biology has not yet been explored.
methodsA selection of both ornamental plants and those of agricultural interest were obtained. A method was developed for the safe instillation of radiopharmaceuticals leading to rapid transport kinetics throughout the plant. [
resultsSeveral plant models were successfully imaged using both radiopharmaceuticals. Owing to differences in dispersion between [
conclusionLAFOV PET/CT systems are feasible for both static and dynamic imaging of different plant models. In vivo biodistribution and kinetics were successfully demonstrated. The longer axial coverage enabled efficient imaging of multiple plants or plants which would not have fitted within the axial FOV of a short-axial PET/CT system.
