In Part I of this study, articles reporting the reliability of CTA up to May 2018 were systematically searched and evaluated. In Part II, 11 raters independently graded 17 arterial segments in each of 50 patients with SAH for the presence of vasospasm using a 4-category scale. Raters were additionally asked to judge the presence of any moderate/severe vasospasm and whether findings would justify augmentation of medical treatment or conventional angiography ± balloon angioplasty. The systematic review revealed few studies with heterogeneous vasospasm definitions. In Part II, the authors found interrater reliability to be moderate at best (ϰ > 0.6), even when results were stratified according to specialty and experience. They conclude that the diagnosis of vasospasm using CTA alone was not sufficiently repeatable among observers to support its general use to guide decisions in the clinical management of patients with SAH.

- EDITOR'S CHOICEAdult BrainOpen AccessMRI Vessel Wall Imaging after Intra-Arterial Treatment for Acute Ischemic StrokeA. Lindenholz, I.C. van der Schaaf, A.G. van der Kolk, H.B. van der Worp, A.A. Harteveld, L.J. Kappelle and J. HendrikseAmerican Journal of Neuroradiology April 2020, 41 (4) 624-631; DOI: https://doi.org/10.3174/ajnr.A6460
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.
