Editor’s Choice Aneurysm wall enhancement regions tend to have lower wall shear stress than nonenhanced regions of the same aneurysm. The association between flow conditions and aneurysm wall enhancement seems to depend on the location of the region on the
Editor’s Choice The authors used pseudospiral Cartesian undersampling with compressed sensing reconstruction to achieve high spatiotemporal resolution (0.5mm isotropic, ∼30 ms) in a scan time of 10 minutes. They analyzed the repeatability of accelerated 4D-flow scans and compared flow rates,
Fellows’ Journal Club Seven giant intracranial aneurysms were evaluated, and 2 aneurysms were available for histopathologic examination. Aneurysm walls were depicted as hypointense in TOF-MRA and SWI sequences with excellent contrast ratios to adjacent brain parenchyma. A triple-layered microstructure of

Imaging the Intracranial Atherosclerotic Vessel Wall Using 7T MRI: Initial Comparison with Histopathology. http://www.ajnr.org/content/36/4/694.full In this preliminary study, 7T imaging was capable of identifying not only intracranial wall thickening but different plaque
