Vessel wall imaging MRI

MR imaging characterization of the vessel wall requires suppression of MR imaging signal arising from luminal blood and CSF (or brain parenchyma for a vessel residing adjacent to the brain) ( Fig 1 C, -D ). Blood-suppression techniques usually exploit the condition of blood flowing and the vessel wall being stationary Background and purpose: Vessel wall imaging is increasingly performed in the diagnostic work-up of patients with ischemic stroke. The aim of this study was to compare vessel wall enhancement after intra-arterial thrombosuction with that in patients not treated with thrombosuction High-resolution intracranial vessel wall MR imaging (VW-MRI) has emerged in recent years as the leading imaging modality for the visualization and characterization of the arterial vessel wall.1-3VW-MRI has a complementary role to luminal imaging techniques, and has been increasingly used as a clinical tool in the diagnosis of intracranial vascular diseases at many centers worldwide.4-16In this installment of the AJNR News Digest, we highlight some of the recent AJNRpublications on VW-MRI Vessel wall imaging protocol included black-blood contrast-enhanced T1-weighted sequences with fat suppression and a saturation band, and time-of-flight MRA of the circle of Willis.

However, DANTE suppresses nonspecific enhancement in a vein (B, curved arrow), which enhances on the non-DANTE sequence (D, arrow) The aim of the present study was to develop an MRI method to image the vessel wall of intracranial arteries, also in the absence of disease. To allow for high-resolution imaging with sufficient sensitivity, MRI was performed at a magnetic field strength of 7.0 T
