Renal dynamic scintigraphy using 3D-ring CZT cameras: comparison with NaI(Tl).
Article in EJNMMI research, 2025. 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
backgroundIsotopic renography is pivotal for assessing upper urinary tract obstruction and provides renal functional parameters. New 3D-CZT cameras offer enhanced sensitivity and innovative full SPECT protocols that need to be validated on phantoms. Current renal phantoms are often complex and suitable for 2D imaging. Using a new printed 3D renal phantom, we compared planar and full SPECT dynamic imaging.
methodsA 3D-printed renal phantom mimicking pediatric/adult kidneys was designed. Each kidney subunit, connected to a bladder-bag, was programmably infused with 7.5 MBq of [
resultsThe 3D printed phantom enabled the acquisition of consistent and reproducible nephrograms. T
conclusionThis innovative 3D phantom allowed the acquisition of reproducible nephrograms with parameters comparable to those of clinical examinations. At low activity, 3D-CZT camera acquisitions provided equivalent values to conventional cameras, supporting their use for qualitative imaging and follow-up.
