Vaussy, C. Hautefort, J.-P. Guichard, A. Guillonet, E. Houdart, A. Attyé and M. EliezerAmerican Journal of Neuroradiology April 2020, 41 (4) 706-711; DOI: https://doi.org/10.3174/ajnr.A6483
The authors compared the degree of perilymphatic enhancement and the detection rate of endolymphatic hydrops using constant and variable flip angle sequences in 16 patients with 3T MR imaging. Both for symptomatic and asymptomatic ears, the median signal intensity ratio was significantly higher with the constant flip angle than with the heavily-T2 variable flip angle. Cochlear blood-labyrinth barrier impairment was observed in 4/18 symptomatic ears with the heavily-T2 variable flip angle versus 8/19 with constant flip angle sequences. They conclude that 3D-FLAIR constant flip angle sequences provide a higher signal intensity ratio and are superior to heavily-T2 variable flip angle sequences in reliably evaluating the cochlear blood-labyrinth barrier impairment.

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.
