Before treatment, there was decreased perfusion in the ipsilateral insula, which was shown to be resolved on the scan obtained 1 day after treatment, indicating the technical success of the revascularization. In the ipsilateral basal ganglia, there was delayed contrast agent clearance from the tissue, which was attributed to vasodilation; after revascularization, there remained a subtle stenotic effect. The observed changes in the dynamic CT perfusion study suggest that this technique may be a useful tool in the evaluation of patients with asymmetrical cerebral blood flow.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/21/2/421}, eprint = {https://www.ajnr.org/content/21/2/421.full.pdf}, journal = {American Journal of Neuroradiology} }
