摘要

Background: Imaging modalities are important part of stroke evaluation. Noncontract head computed tomography (CT) is the initial imaging modality in acute stroke and although important to rule out acute hemorrhage and making a decision on thrombolytic treatment, ischemic changes may not be visible on CT for up to 24 hours. Magnetic resonance imaging (MRI) brain is an invaluable tool to confirm an ischemic stroke and facilitates stroke evaluation. Objective of this study was to investigate the correlation between time to MRI and length of hospital stay. Methods: A total of 432 patients admitted to Hartford Hospital (Comprehensive Stroke Center) with a focal neurological deficit in the year 2014 and got a CT head and MRI brain were enrolled in the study. Data collection was done via stroke database and retrospective chart review. Patients with any hemorrhage or age 18 years were excluded from the study. Patients were categorized as having had an early (within 12 hours) or a late (more than 12 hours) MRI. We used chi-square and Wilcoxon ranked sum test to compare time from arrival to MRI and length of stay in the hospital. Results: There was a statistically significant difference in hospital length of stay between patients who obtained MRI within 12 hours, as compared with patients who had MRI greater than 12 hours after admission, early MRI group 3 days (1.8, 4.9) versus 4 days (2.6, 7.0), P .001. Conclusions: Our study suggests that brain MRI performed within 12 hours of admission facilitates stroke evaluation and decreases hospital length of stay. It provides evidence for cost effectiveness of MRI in ischemic stroke.
