The Necessity of Using MRI as an Imaging Modality in Acute Code Stroke in Indonesia

To evaluate the performance and outcomes of the 6-minute magnetic resonance imaging (MRI) protocol in diagnosing stroke within Indonesian healthcare setting compared to computed tomography (CT).

This retrospective single-center study was conducted at the Universitas Indonesia Hospital in Depok, Indonesia from September 2021 to September 2023. Patients who were diagnosed with acute stroke underwent a clinical evaluation and a 6-minute MRI protocol. The primary objective was to assess the efficiency of the 6-minute MRI protocol in promptly and accurately evaluating acute stroke patients, including determining average MRI time, thrombolysis eligibility, and post-thrombolysis outcomes compared to CT imaging. Exclusions comprised those requiring resuscitation, lack of stroke code activation, or having incomplete documentation.

This study involved 182 stroke patients, 136 of which underwent MRI and 46 had CT scans. Thrombolysis eligibility was similar between the groups (48.9% for MRI vs 47.8% for CT-Scan), but a higher proportion of eligible MRI patients received thrombolysis (70.1% vs 54.5%, p = 0.037). MRI also achieved shorter door-to-imaging times, especially from February to June 2022. Among those treated for ischemic stroke via MRI, 70.3% showed improvement compared to 55% for CT (p=0.016). Door-to-MRI times varied across periods, averaging 88.2 minutes before national healthcare insurance collaboration, 29.1 minutes during transition, and 47.8 minutes afterward.

This study emphasizes the crucial role of the 6-minute MRI protocol for accurately diagnosing stroke types, severity, and determining thrombolysis eligibility. Positive outcomes in thrombolysis patients using this protocol highlight its effectiveness. However, prolonged time-to-MRI indicates the need for further improvement. Optimizing time management and workflow efficiency are critical for improving treatment efficacy and safety.
