- MRI Vessel Wall Imaging after Intra-Arterial Treatment for Acute Ischemic Stroke
The authors compared vessel wall enhancement after intra-arterial thrombosuction with that in patients not treated by thrombosuction in a group of 49subjects with ischemic stroke with 7T MR imaging within 3 months after symptom onset. In the intra-arterial treatment group, 11 of 14 patients (79%) showed vessel wall enhancement compared with 17 of 35 patients without intra-arterial treatment (49%). In the intra-arterial treatment group, more enhancing foci were detected on the ipsilateral side compared with the contralateral side. They conclude that patients with intra-arterial treatment by means of thrombosuction showed more (concentric) enhancing foci of the vessel wall ipsilateral compared with contralateral to the treated artery than the patients without intra-arterial treatment, suggesting reactive changes of the vessel wall.
- Neuroradiology Fellowship Requirements: Updates in 2019
Notable changes made since the prior requirements were last revised in 2007 primarily affect the number of required procedures, the academic support defined for the program director, and modifications to the curriculum. The new requirements allow fellows to fulfill the foundational expectations for the neuroradiology fellowship and encourage programs to maintain some flexibility to teach individual specialty areas of clinical excellence.
