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.

- FELLOWS' JOURNAL CLUBAdult BrainOpen AccessHippocampal Sclerosis Detection with NeuroQuant Compared with NeuroradiologistsS. Louis, M. Morita-Sherman, S. Jones, D. Vegh, W. Bingaman, I. Blumcke, N. Obuchowski, F. Cendes and L. JehiAmerican Journal of Neuroradiology April 2020, 41 (4) 591-597; DOI: https://doi.org/10.3174/ajnr.A6454
The authors reviewed 144 adult patients who underwent presurgical evaluation for temporal lobe epilepsy. The reference standard for hippocampal sclerosis was defined by having hippocampal sclerosis on pathology (n=61) or not having hippocampal sclerosis on pathology (n=83). Sensitivities, specificities, positive predictive values, and negative predictive values were compared between NeuroQuant analysis and visual MR imaging analysis. Visual MR imaging analysis by a neuroradiologist with expertise in epilepsy had a higher sensitivity than did NeuroQuant analysis, likely due to the inability of NeuroQuant to evaluate changes in hippocampal T2 signal or architecture. Given that there was no significant difference in specificity between NeuroQuant analysis and visual MR imaging analysis, NeuroQuant can be a valuable tool when the results are positive, particularly in centers that lack neuroradiologists with expertise in epilepsy, to help identify and refer candidates for temporal lobe epilepsy resection.
