“…Theoretically, the ideal VW imaging protocol would include images of all three image contrast weightings and a T1-weighted sequence after contrast agent administration to assess intracranial VW disease in the same fashion as has been done for years for their extracranial counterparts (46). However, no clear evidence yet exists on the clinical relevance of multicontrast MR imaging protocols for intracranial VW disease.…”

“…MRI also can assess the presence of neovasculature in carotid artery plaques [82][83][84][85]. A recent study by Gaens et al [85] showed that dynamic contrast-enhanced MR of carotid atherosclerotic plaques can assess plaque neovasculature and that the Patlak model is well-suited for describing carotid plaque enhancement; the authors found that the K(trans) is an indicator of plaque microvasculature (validated by histology) and that the reproducibility of K(trans) was good.…”

Atherosclerosis involving the carotid arteries has a high prevalence in the population worldwide. This condition is significant because accidents of the carotid artery plaque are associated with the development of cerebrovascular events. For this reason, carotid atherosclerotic disease needs to be diagnosed and those determinants that are associated to an increased risk of stroke need to be identified. The degree of stenosis typically has been considered the parameter of choice to determine the therapeutical approach, but several recently published investigations have demonstrated that the degree of luminal stenosis is only an indirect indicator of the atherosclerotic process and that direct assessment of the plaque structure and composition may be key to predict the development of future cerebrovascular ischemic events. The concept of ''vulnerable plaque'' was born, referring to those plaque's parameters that concur to the instability of the plaque making it more prone to the rupture and distal embolization. The purpose of this review is to describe the imaging characteristics of ''vulnerable carotid plaques.''

“…9 This technique, which requires dedicated surface coils, has been used extensively for carotid atherosclerosis and, more recently, for carotid dissection. [10][11][12] Except for 1 case study, 13 there are no data in the literature that support a role for HR-MR imaging in the diagnosis of VAD.…”

BACKROUND AND PURPOSE:The optimal imaging method for the diagnosis of VAD remains undefined. Our aim was to evaluate the added value of HR-MR imaging for the diagnosis of VAD. MATERIALS AND METHODS:We retrospectively extracted 35 consecutive patients suspected of having acute VAD who had the following: 1) a focal lumen abnormality of the VA on CE-MRA, 2) HR-MR imaging during the initial hospital stay, and 3) clinical and imaging follow-up within 6 months. Two neurologists classified patients as either VAD (group A) or non-VAD (group B) by reviewing all the available data at hospital discharge, except HR-MR imaging data. On HR-MR imaging, 2 radiologists searched for signs of acute VAD. The 2 classifications were compared. In case of discordance, CE-MRA follow-up and axial fat-suppressed T1WI, used to obtain supportive evidence for or against VAD, were considered as the standard of reference. RESULTS:In 4/18 patients in group A, HR-MR imaging did not demonstrate any signs of acute VAD and perivertebral signal-intensity changes were attributed to venous plexus, with an unchanged lumen on follow-up. In 4/17 patients in group B, HR-MRI demonstrated a mural hematoma, with lumen normalization on follow-up CE-MRA. CONCLUSIONS:Our results encourage the use of HR-MR imaging as a second-line diagnostic tool in the event of suspicion of acute VAD and doubtful findings on standard imaging.ABBREVIATIONS: CE-MRA ϭ contrast-enhanced MR angiography; CI ϭ confidence interval; DSA ϭ digital subtraction angiography; DUS ϭ Doppler ultrasonography examination; DWI ϭ diffusionweighted imaging; HR ϭ high resolution; NIHSS ϭ National Institutes of Health Stroke Scale; PDWI ϭ proton attenuationϪweighted imaging; T1WI ϭ T1-weighted imaging; T2WI ϭ T2-weighted imaging; TE eff ϭ effective echo-time; TOF ϭ time of flight; V2 and V3 ϭ the second and third VA segments; VA ϭ vertebral artery; VAD ϭ VA dissection
