An 88-year-old male patient, suffering from a sudden onset of right-sided hemiplegia as well as aphasia and unconsciousness, was diagnosed with an acute ischemic stroke in an external hospital. He was referred to our hospital and underwent intra-arterial recanalization (IAR). A control Dual Energy (DE) CT was performed right after the recanalization.
