      This is a retrospective subanalysis of the IntrePED study, which has beenpreviously published (AJNR Am J Neuroradiol 2015;36:108–15).Seven hundred ninety-three patients with 906 treated aneurysms were enrolled. Thirty-six (4.5%) patients had postoperative acute ischemic stroke, 21 of which occurred within 1 week of the procedure. There was no difference in the rate of acute stroke between the anterior and posterior circulations. Stroke rate was 3% in patients with 1 PED, and 7% in those with 2 PEDs. With multivariate analysis, the only variable independently associated with postoperative stroke was treatment of fusiform aneurysms. Among the patients with stroke, 10 (27.0%) died and 26 (73.0%) had major neurologic morbidity. The authors conclude that acute ischemic stroke following treatment of intracranial aneurysms with the PED is an uncommon but devastating complication, with 100% of patients having major morbidity or mortality.

      Quantitative Susceptibility Mapping and R2* Measured Changes during White Matter Lesion Development in Multiple Sclerosis: Myelin Breakdown, Myelin Debris Degradation and Removal, and Iron Accumulation
      Y. Zhang, S.A. Gauthier, A. Gupta, W. Chen, J. Comunale, G.C.-Y. Chiang, D. Zhou, G. Askin, W. Zhu, D. Pitt and Y. Wang
      American Journal of Neuroradiology September 2016, 37 (9) 1629-1635; DOI: https://doi.org/10.3174/ajnr.A4825

      The authors characterized lesion changes on quantitative susceptibility mapping and R2* at various gadoliniumenhancementstages (nodular, shell-like, nonenhancing) in 64 patients with 203 lesions. They found that: 1) active MS lesions with nodular enhancement show R2* decrease but no quantitative susceptibility mapping change; 2) late active lesions with peripheral enhancement show R2* decrease and quantitative susceptibility mappingincrease in the lesion center; and 3) nonenhancing lesions show both quantitative susceptibility mapping and R2* increase, reflecting iron accumulation.

      The authors retrospectively studied clinical and radiologic data of 333 consecutive patients with aneurysmal SAH between January 2009 and December 2011. Adjusted odds ratios werecalculated for the association between automatically quantified total blood volume on NCCT and delayed cerebral ischemia (clinical, radiologic, and both). The adjusted OR of total blood volume for delayed cerebral ischemia was 1.02 per milliliter of blood. They conclude that a higher total blood volume measured with the automated quantification method is significantly associated with delayed cerebral ischemia.
