      Prediction of Hemorrhage after Successful Recanalization in Patients with Acute Ischemic Stroke: Improved Risk Stratification Using Dual-Energy CT Parenchymal Iodine Concentration Ratio Relative to the Superior Sagittal Sinus
      D. Byrne, J.P. Walsh, H. Schmiedeskamp, F. Settecase, M.K.S. Heran, B. Niu, A.K. Salmeen, B. Rohr, T.S. Field, N. Murray and A. Rohr

      The authors evaluated whether, in acute ischemic stroke, iodine concentration within contrast-stained parenchyma compared with an internal reference in the superior sagittal sinus on dual-energy CT could predict subsequent intracerebral hemorrhage in 71 patients. Forty-three of 71 patients had parenchymal hyperdensity on initial dual-energy CT. The median relative iodine concentration compared with the superior sagittal sinus was significantly higher in those with subsequent intracerebral hemorrhage (137.9% versus 109.2%). They conclude that in dual-energy CT performed within 1 hour following thrombectomy that the relative iodine concentration within contrast-stained brain parenchyma compared with that in the superior sagittal sinus was a more reliable predictor of ICH compared with the absolute maximum iodine concentration.

      Vessel Wall Thickening and Enhancement in High-Resolution Intracranial Vessel Wall Imaging: A Predictor of Future Ischemic Events in Moyamoya Disease

      American Journal of Neuroradiology January 2020, 41 (1) 100-105; DOI: https://doi.org/10.3174/ajnr.A6360

      Twenty-nine patients with Moyamoya disease were enrolled in this study. The median age at symptom onset was 12 years. A total of 166 steno-occlusive lesions were detected by high-resolution intracranial vessel wall imaging. Eleven lesions with concentric wall thickening (6.6%) were noted in 9 patients. Ten concentric contrast-enhancing lesions were observed in 8 patients, of which 4 lesions in 3 patients showed grade II enhancement. The presence of contrast enhancement and wall thickening showed a statistically significant association with ischemic events within 3 months before and after the vessel wall imaging. The presence of wall thickening and enhancement may predict future ischemic events in patients with MMD.
