In recent years, with the rapid advancement of ultrasound technology, novel techniques such as contrast-enhanced ultrasound (CEUS) and Superb Microvascular Imaging (SMI) have emerged, substantially improving the accuracy of hemodynamic assessments and expanding their clinical applications. Regarding research background and significance, alterations in arterial blood flow parameters are closely associated with various vascular pathologies (e.g., peripheral artery stenosis, thrombosis). Early and accurate assessment facilitates timely diagnosis, risk stratification, and formulation of therapeutic decisions. The main research content encompasses: Detection methods for ultrasound hemodynamic parameters (e.g., flow velocity, resistive index, pulsatility index). Application advances across different arterial systems (e.g., carotid, renal, and peripheral arteries) technological breakthroughs in hemodynamic research using new imaging modalities. Clinical value analysis demonstrates that ultrasound assessment of blood flow parameters not only enables disease diagnosis and severity grading but also predicts disease risk, guides treatment planning, and plays a vital role in postoperative follow-up and scientific research. Looking ahead, integration with AI-based analytics is anticipated to further enhance the precision and clinical potential of ultrasound-based hemodynamic evaluation.
