Obese patient imaging: Potential dose reduction with photon-counting CT.
Article in Journal of applied clinical medical physics, 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
backgroundPhoton-counting CT (PCCT) offers key advantages over energy integrating detector CT (EID-CT), especially in low-dose scans and imaging larger patients. As obesity rates rise, minimizing image noise is critical for diagnostic accuracy. PURPOSE: To evaluate the dose efficiency of cadmium-zinc-telluride (CZT) based PCCT compared to EID-CT across phantom sizes.
methodsA patient-specific 3D-printed pancreas phantom and a phantom with tissue mimicking inserts were placed in extension rings corresponding to the 50
resultsPCCT demonstrated reduced noise compared to EID-CT across all phantom sizes and doses with average noise reductions of 22%, 23%, 25%, and 28% for the 50
conclusionsPCCT exhibited superior dose efficiency compared to EID-CT across a range of phantom sizes. The enhanced dose efficiency enables both noise reduction and potential dose reduction for the imaging of obese patients and low-dose imaging applications. Further evaluation with task-based image quality metrics remains necessary before clinical implementation of dose reduction.
