对9例疑似颈椎血管夹层患者的MRI和血管造影结果进行回顾性比较，发现8例患者MRI显示血管异常，其中7例证实为动脉夹层。一名MRI未显示异常的患者也被血管造影证实有夹层。2例患者伴有假性动脉瘤，MRI未发现。其中5例涉及颈动脉，3例涉及椎动脉。九名患者中有七名有相关的短暂性神经功能缺陷，而两名有永久性缺陷。5例经MRI证实为明显脑梗死。提示夹层的MRI表现包括：(1)全血管信号增强；(2)管腔周围信号增强，管腔变窄；(3)血管可视性差或缺失；(4)邻近异常增加的信号组织明显损害血管管腔。
Retrospective correlation of MRI and angiographic findings in nine patients with suspected cervical vascular dissections revealed MRI evidence of vessel abnormalities in eight patients, seven of whom proved to have arterial dissections. One patient whose MRI showed no abnormalities also proved to have a dissection, shown by angiography. Two patients had associated pseudoaneurysms not demonstrated by MRI. Five dissections involved the carotid arteries and three the vertebral arteries. Seven of the nine patients had associated transient neurologic deficits, while two had permanent deficits. Frank infarction of the brain was demonstrated by MRI in five cases. MRI findings suggestive of dissection included: (1) increased signal from the entire vessel; (2) a border of increased signal surrounding the lumen, with luminal narrowing; (3) poor or absent visualization of the vessel; and (4) significant compromise of the vessel lumen by adjacent abnormal increased signal tissue.
