ABSTRACT
The reported sensitivity of neurovascular ultrasound (nUS) for detecting spontaneous cervical artery dissection (sCAD) varies from 80% to 96% in the internal carotid artery (ICA) and from 70% to 86% in the vertebral arteries (VA). The aim of this study was to assess the sensitivity of nUS compared to MRI of the neck and MR angiography for the detection of sCAD. Forty consecutive patients with sCAD proven by 1.5T MRI were investigated by nUS within 48 hours of admission. A total of 52 cases of sCAD were detected by MRI, equally distributed (n=26, 50%) in the ICA and VA territories. Two sCADs affecting the ICA (n=2, 8%) and two sCADs of the VA (n=2, 8%) had normal initial nUS findings. The sensitivity of nUS in detecting sCAD is high, about 92% for both vascular territories. However, intramural hematomas may be missed either when they are located outside the arterial segments directly visible by nUS or if they are too small to cause hemodynamically significant stenosis.
