Oral Session O1-1 Intracranial high-density areas after interventional neuroradiology: Usefulness of dual-layer spectral detector CT for differentiating hemorrhage from extravasation of contrast media 1
Department of Radiology, University of Miyazaki, 2 Depart of Neurosurgery, University of Miyazaki Youhei Hattori1, Minako Azuma1, Yoshihito Kadota1, Toshinori Hirai1, Hideo Takeshima2 We aimed to investigate whether dual-layer spectral detector CT (DSD-CT) images are useful for discriminating between hemorrhage and extravasation of iodine contrast media in patients with intracranial high-density areas on CT after intracranial high-density areas after interventional neuroradiology (IVNR). We included 4 patients with meningioma, 2 with cerebellar hemangioblastoma and 2 with unruptured cerebral aneurysm, who underwent DSD-CT immediately after endovascular embolization. We evaluated the high-density areas around the embolized lesion using virtual non-contrast CT (VNC-CT) and iodine density images. All the high-density areas disappeared on VNC-CT and showed the presence of iodine on the iodine density images. Follow-up CT/MRI and intraoperative findings showed no hemorrhage in any of the patients. DSD-CT is useful for discriminating between hemorrhage and extravasation of iodine contrast media in patients with high-density areas on CT after IVNR.
