In analyzing a subset of 12 patients (pilot study) who had both completion carotid ... The velocity data were expressed as mean ± standard deviation. Comparison of the duplex ultrasound velocity ...

Abstract: Accurate measurement of carotid plaques in ultrasound images is essential for the early prevention and intervention of stroke. However, carotid plaques exhibit complex and diverse shapes, ...

most studies directly use raw ultrasound images as input to end-to-end networks. The noise and high-dimensional features in these images increase both network complexity and the number of parameters.

Sixty-three percent were done for ≥ 70% asymptomatic carotid stenosis and 37% for strokes ... ROC Curves: Sensitivity and Specificity of Various Velocity Criteria Peak Systolic Velocity.

We compared relative changes in middle cerebral artery velocity and internal carotid artery flow during autoregulation testing to test the validity of using transcranial Doppler recordings of middle ...

This study included patients diagnosed with CAS or occlusion through imaging tools (carotid ultrasound and CTA) who met the criteria for CEA (36 ... Parameters such as intima-media thickness, inner ...
