Comparison of MRI-based thrombolysis for patients with middle cerebral artery occlusion ≤ 3 h and 3-6 h

OBJECTIVE: To investigate the outcomes of magnetic resonance imaging (MRI)-based thrombolysis using recombinant tissue plasminogen activator (rt-PA) in patients with acute middle cerebral artery (MCA) occlusion in 3-6 hours. MATERIALS AND METHODS: MRI-selected patients (n=15) with acute ischemic stroke in MCA divided into two groups (
