Radiation dose of coronary CT angiography with a third-generation dual-source CT in a "real-world" patient population.
Article in European radiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers.
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
objectivesTo assess radiation dose and image quality of coronary computed tomography angiography (cCTA) with a third-generation dual-source scanner in a real-world patient population.
methodsScans of otherwise unselected, consecutive patients referred for clinically indicated cCTA between June 2015 and November 2017 were included for retrospective analysis. Scan protocol was based on heart rate: prospectively ECG-gated high-pitch spiral below 60 beats per minute (bpm), prospectively ECG-gated sequential scan between 61 and 70 bpm, and retrospective spiral above 70 bmp or at irregular heart rates. Objective image quality was measured as signal-to-noise (SNR) and contrast-to-noise ratio (CNR); subjective image quality was evaluated using a five-point Likert scale by two independent readers. For radiation dose analysis, effective dose, size-specific dose estimates, and volume CT dose index were assessed.
resultsTwo hundred seventy-eight patients (median age, 60 years; 155 men) with a median body mass index of 26.6 kg/m
conclusionscCTA with sufficient image quality is achievable at reasonably low radiation exposure in a real-world patient collective with a high proportion of overweight or obese patients. KEY POINTS: • Submillisievert radiation dose coronary CT angiography with good diagnostic image quality is feasible in the majority of cases in a real-world patient using high-pitch spiral. • Prospective sequence results in about double median effective dose compared to the high-pitch protocol. • To optimize individual radiation exposure, lowering the heart rate is paramount, as it allows for choosing a dose-optimized (high-pitch spiral) scan protocol.
