Minimizing contrast agent dosage in CT angiography using a saline chaser with a low trigger threshold.

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
Background: Computed tomography angiography (CTA), utilizing iodinated contrast agents, is a first-line diagnostic tool for cardiovascular diseases (CVD). However, the administration of contrast agents introduces potential risks to patients. Objective: This study aims to design a novel protocol for CTA that integrates a saline chaser strategy and low-threshold triggering and evaluate, and demonstrate its feasibility and practicality minimizing the required contrast agent for imaging. Methods: A novel protocol for CTA incorporating a saline chaser strategy and low-threshold triggering was developed. Random assignment of eighty patients undergoing CTA examinations divided them into conventional and novel protocol groups. The assessment encompassed iodine intake, radiation dose, image quality, and superior vena cava artefacts in both cohorts. Results: The novel protocol group exhibited a noteworthy 20% reduction in iodine intake compared to the conventional group ( Conclusion: The combination of saline chaser strategy with low-threshold triggering in CTA imaging proves a viable approach, significantly curtailing the utilization of iodinated contrast agents, and superior vena cava artefacts.
