Qualitative Evaluation of a High-Resolution 3D Multi-Sequence Intracranial Vessel Wall Protocol at 3 Tesla MRI
BACKGROUND AND PURPOSE Intracranial vessel wall imaging using MRI has great potential as a clinical method for assessing intracranial atherosclerosis. The purpose of the current study was to compare three 3T MRI vessel wall sequences with different contrast weightings (T1w, PD, T2w) and dedicated sagittal orientation perpendicular to the middle cerebral artery, to the reconstructed sagittal ima...
متن کاملDevelopment of a clinically practical whole-brain intracranial vessel wall MRI technique at 3 Tesla
Background T1-weighted variable-flip-angle 3D TSE has emerged as a promising intracranial vessel wall imaging technique. To increase spatial coverage and cerebrospinal fluid (CSF) attenuation, a whole-brain 0.5-mm-reoslution protocol based on an inversion-prepared 3D TSE sequence has recently been proposed at 3T. However, its 11-12-min scan time renders it clinically impractical. This work aime...
متن کاملIntracranial arterial wall imaging using high-resolution 3-tesla contrast-enhanced MRI.
BACKGROUND Conventional arterial imaging focuses on the vessel lumen but lacks specificity because different pathologies produce similar luminal defects. Wall imaging can characterize extracranial arterial pathology, but imaging intracranial walls has been limited by resolution and signal constraints. Higher-field scanners may improve visualization of these smaller vessels. METHODS Three-tesl...
متن کاملHigh resolution wall and lumen MRI of the middle cerebral arteries at 3 tesla.
BACKGROUND Although black-blood MRI (BB-MRI) can identify plaques in the cervical carotid arteries, this modality has not been applied in intracranial arteries. We imaged the lumina and walls of stenotic middle cerebral arteries (MCAs) in symptomatic and asymptomatic patients using high-resolution BB-MRI, in order to characterize vulnerable plaques and to determine the diagnostic accuracy of BB...
متن کاملIntracranial Arterial Wall Imaging using 3D High Isotropic-Resolution Black Blood MRI at 3.0 T
INTRODUCTION: The presence of intracranial vascular disease is highly predictive of stroke. However, disease prevalence may be underestimated due to the lack of an appropriate diagnostic tool to depict the intracranial vessel wall [1]. Black blood MRI (BBMRI) has emerged as an effective method to identify pathological features of extracranial vessels [2]. Recently, it has been extended to evalu...
