Exploring the Role of In-patient Magnetic Resonance Imaging Use Among Admitted Ischemic Stroke Patients in Improving Patient Outcomes and Reducing Healthcare Resource Utilization.

Abstract

Purpose: Despite the diagnostic and etiological significance of in-patient MRI in ischemic stroke (IS), its utilization is considered resource-intensive, expensive, and thus limiting feasibility and relevance. This study investigated the utilization of in-patient MRI for IS patients and its impact on patient and healthcare resource utilization outcomes.
