Utilities values are average utility values for the group of patients with the corresponding 90-day mRS scores. Lifetime discounted QALYs are the expected quality adjusted life years of people having respective 90-day mRS scores. Time to perform each of the imaging procedure, and interval time between patients in the CT scanner.
