ObjectiveThis study explored the feasibility of using high‐frame‐rate ultrasound vector flow imaging (VFI) to quantitatively assess hemodynamics in atherosclerotic internal carotid artery stenosis (ICAS) by evaluating dual‐parameters, turbulence index (Tur), and wall shear stress (WSS). Their efficacy in evaluating carotid artery stenosis was also analyzed.MethodsFifty‐nine patients with ICAS were enrolled. B‐mode ultrasound and V Flow (a high‐frame‐rate VFI) were performed using the Resona R9 system. The stenosis rate was measured in grayscale mode, whereas the time‐averaged Tur index, the time‐averaged WSS (WSSmean), and maximum WSS (WSSmax) around stenosis were measured. The combined diagnostic efficacy of Tur inand WSS was also investigated.ResultsCompared to proximal to stenosis (Tur index, 2.88% ± 3.65%), highly disordered blood flow was observed in the stenotic (23.17% ± 15.52%, p < 0.001) and distal segment (25.86% ± 17.29%, p < 0.001). WSSmax ([11.91 ± 6.73] vs. [4.43 ± 5.4] Pa, p < 0.001) and WSSmean ([3.42 ± 2.67] vs. [0.86 ± 1.21] Pa, p < 0.001) were significantly bigger in stenotic than those in the distal segment. The differences in the ratio WSSmax/Tur or WSSmean/Tur among different segments around stenosis were statistically significant (p < 0.001). The combination of Tur index and WSS had the best diagnostic performance in ICAS (AUC, 0.899).ConclusionThe application of Tur index and WSS for quantitative assessment of ICAS hemodynamic changes is feasible, with the combined evaluation of these two parameters providing incremental diagnostic value for carotid artery stenosis. VFI‐based dual quantitative parameters may offer promising noninvasive diagnostic tools for carotid artery stenosis in high‐stroke‐risk populations.

Left ventricular (LV) systolic function can be evaluated using echocardiography by ejection fraction (by LV volume in 2D and 3D methods), Tissue Doppler Imaging or myocardial strain by 2D or 3D speckle tracking echocardiography-STE, global longitudinal strain-GLS, radial strain-GRS, and circumferential strain-GCS, and associated peak strain rates (GLSr, GRSr, GCSr). Besides longitudinal myocardial deformation, radial, and circumferential myocardial deformation is important in understanding myocardial motion in the short-axis direction. In addition, there are some new derived STE methods, which are not part of the daily clinical practice. Novel techniques derived from STE have gained advantages in overcoming the disadvantages of classical deformation methods. However, Tissue Doppler Imaging was the first method used for directly measuring myocardial deformation by echocardiography. Due to the angle dependency, it is now less used, being replaced by GLS and vector velocity imaging (VVI). There is no echocardiographic technique in 2D or 3D, which is perfect, each of them having advantages and disadvantages (Figure 1). Jianwei Shi et al1 assessed the LV systolic function in patients with Parkinson's disease by LV ejection fraction, GLS, GRS, and GCS, and their associated peak strain rates. They analyzed the correlation between LV dysfunction and the severity of Parkinson's disease symptoms using the modified Hoehn-Yahr scale. This score and the Parkinson's disease duration were correlated with reduced LV systolic function. The severity of LV impairment was influenced by blood pressure, heart rate variability, and blood glucose. The authors considered that it is feasible to assess subclinical LV global systolic dysfunction in patients with Parkinson's disease by VVI. 1 This study is very important for clinical practice because monitoring the cardiac function in patients with Parkinson disease, the second most prevalent neurodegenerative disease, will allow the detection of the progression of this disease.
