This single protocol combines the carotid plaque imaging (carotid plaque imaging) and the CREST-H imaging (H-MRI) sequences. Three modalities must be used: B‐mode gray scale imaging, color flow Doppler, both on transverse and longitudinal planes, and spectral Doppler velocities on longitudinal planes. If the stenosis is measured by ultrasound prior to the procedure, then the. Hindrances in the classification of problematic carotid artery stenoses may be overcome by following a standard protocol and optimizing scanning techniques and Doppler settings. A carotid ultrasound is an important test that can detect narrowing, or stenosis of the carotid arteries. Three different-angle manual measurements (IMTindiv) were obtained.
