Comparison of Radiation Dose Between Dedicated Cardiac and General-Purpose Angiography Systems in Coronary Intervention.
Article in Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 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
backgroundCoronary intervention contributes substantially to patient radiation exposure. While dedicated cardiac angiography systems are optimized for coronary imaging, general-purpose systems are frequently used due to resource constraints.
aimsThe radiation dose difference between these system types during routine coronary procedures performed by the same operator team remains poorly quantified.
methodsThis retrospective study enrolled 212 patients undergoing coronary procedures by the same operator team, allocated to dedicated cardiac (Philips Azurion 7 M12, n = 106) or general-purpose (Philips Azurion 7 M20, n = 106) systems based on room availability. Procedures were stratified into diagnostic angiography (n = 106) and percutaneous coronary intervention (PCI) (n = 106). Primary endpoints were total dose-area product (DAP) and air kerma (AK). Secondary endpoints included fluoroscopy DAP, acquisition DAP, fluoroscopy time, and estimated magnification mode usage.
resultsBaseline characteristics were balanced between groups. In diagnostic angiography, total DAP was 18.3% lower with the cardiac system (1850 vs. 2260 μGy·m
conclusionsDedicated cardiac angiography systems achieve 18%-22% lower radiation doses in coronary procedures compared to general-purpose systems, driven by more efficient acquisition algorithms and associated with reduced magnification mode usage as a behavioral marker, without increased fluoroscopy time.
