- Regional Aneurysm Wall Enhancement is Affected by Local Hemodynamics: A 7T MRI Study
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 aneurysm sac. Regions at the neck and close to the inflow tend to be exposed to higher wall shear stress and wall shear stress gradients.
- 3D Quantitative Synthetic MRI in the Evaluation of Multiple Sclerosis Lesions
Three-dimensional synthetic MR imaging could serve as an alternative to conventional MR imaging in evaluating MS with a reduced scan time.
- Involvement of the Spinal Cord in Primary Mitochondrial Disorders: A Neuroimaging Mimicker of Inflammation and Ischemia in Children
Spinal cord lesions are frequently observed in children with mitochondrial disorders and may mimic more common causes such as demyelination and ischemia.
- Dural Venous Sinus Stenosis: Why Distinguishing Intrinsic-versus-Extrinsic Stenosis Matters
Most patients in this study with idiopathic intracranial hypertension had extrinsic stenosis, and most patients with pulsatile tinnitus had intrinsic stenosis. Awareness and reporting of these subtypes may reduce the under-recognition of potential contributory stenoses in a given patient's idiopathic intracranial hypertension or pulsatile tinnitus.
