In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi-Cycle Phase Clustering Ultrafast Ultrasound.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Echocardiography is the most primary clinical modality for dynamic cardiac imaging. However, the vigorous motion of myocardial tissue inherently causes inevitable signal aliasing between blood flow and myocardial tissue in traditional Doppler ultrasound imaging, constituting a persistent challenge in echocardiography for decades. Particularly for low-velocity flows like coronary artery blood flow, the Doppler frequency shifts completely overlap with myocardial tissue signal shifts, rendering them virtually undetectable through conventional echocardiography. This study pioneers a paradigm shift by abandoning traditional Doppler-based blood flow imaging, and develops a novel multi-cycle phase clustering method for tissue clutter suppression, successfully extracting dynamic cardiac blood flow signals with clear visualization of both coronary artery flow and cardiac chamber flow throughout the full cardiac cycle. Furthermore, through integration with super-resolution ultrasound reconstruction techniques, enhanced spatial resolution in cardiac blood flow imaging is achieved. This breakthrough establishes a novel in vivo cardiovascular flow imaging approach characterized by high spatio-temporal resolution, safety, and clinical accessibility, demonstrating significant potential for advancing the diagnosis of cardiovascular diseases.
