High-frame-rate ultrasound analysis of gastric peristalsis using the peristaltic analyzer: a pilot feasibility study

As the first application of the PA high-frame-rate peristaltic analysis technology to gastric motility assessment, this study demonstrates its strong potential as a non-invasive and real-time tool for early detection, quantitative monitoring, and clinical evaluation of functional gastrointestinal disorders. PA exhibited superior performance in motion detection, directional analysis, and fine-scale displacement measurement. These capabilities highlight its potential as a novel tool for early identification and longitudinal monitoring of functional gastrointestinal disorders, postoperative gastric dysmotility, and diabetic gastroparesis, offering substantial clinical translational value and applicability.
