Takeaway
Magnetic resonance imaging (MRI)-guided thrombolysis in stroke patients with minor deficits is safe and effective.
Why this matters
Current US guidelines for stroke management recommend consideration of intravenous thrombolysis (IVT) in patients with acute stroke and a mild deficit, but IVT is often withheld in these patients.
Understanding the effects of IVT in stroke patients with mild and non-disabling deficits will likely improve treatment outcomes.
