MDSV should not yet guide carotid stenosis management; leaves open its value as a vulnerability marker for prospective validation.
Does 4-dimensional ultrasonography identify differences in plaque surface motion between symptomatic and asymptomatic patients with carotid artery stenosis?
Four-dimensional ultrasonography reveals that symptomatic carotid plaques have significantly higher maximal discrepant surface velocity than asymptomatic plaques, suggesting a potential imaging marker for plaque vulnerability.
Meairs et al. (1999) studied this question.
