Follow up Dual A follow-up dual-energy CT of the brain was performedimmediately after endovascular thrombectomy.
ItsIt showed cerebral gyriform hyperdensities within the right temporoparietal cortical region as well as within the right sylvianSylvian fissure and interpeduncular cistern in both the iodine overlay map (IOM), and virtual monoenergetic non-contrast images (VNC).
Features are in favoring of favour contrast staining rather than bleeding.
