Comparison of SZ-HRX and LEHR collimators for reduced-duration 123I-ioflupane brain SPECT/CT: a phantom study.
Article in EJNMMI physics, 2025. 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.

resultsSZ-HRX collimation had superior performance characteristics than LEHR, with relative changes in CNR, CV, and SBR of + 99%, -28% and + 42% respectively, without any decrease in spatial resolution or change in asymmetry index. SZ-HRX system seems to be at least as good as LEHR system, up to 40% of scan time reduction.
conclusionSZ-HRX collimation showed superior performance characteristics to LEHR collimation in the study of
