Correlation between characteristics of carotid stenosis and lesions on MRI

Problemstellung: The relationship between characteristics of internal carotid artery (ICA) stenosis (microemboli, cerebral vasoreactivity) and types of stroke have not been systematically studied. Patienten und Methode: Among 100 consecutive patients referred to our neurosonology unit, 52 were included in a 2-years period. Inclusion criteria were 50–99% ICA stenosis (PSV>120cm/s or poststenotic flow reduction). Within a month, we also performed microembolic signals (MES) detection, cerebral vasoreactivity, TCCD ultrasonography and cerebral MRI. We excluded patients with known embolizing cardiopathy, tandem steno…
