This study highlights the critical role of advanced neuroimaging in acute stroke management. Computed tomography and magnetic resonance imaging, including diffusion-weighted imaging and perfusion studies, are essential for diagnosing stroke and guiding thrombolytic therapy.

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Stroke is a sudden neurological deficit from intracranial hemorrhage or ischemia.
  • Computed tomography (CT) is pivotal in acute stroke evaluation.
  • Magnetic resonance imaging (MRI) offers advanced diagnostic capabilities.

Purpose of the Study:

  • To outline the optimal neuroimaging protocols for acute stroke.
  • To emphasize the importance of accurate diagnosis for treatment selection.
  • To discuss the role of imaging in thrombolytic therapy decisions.

Main Methods:

  • Utilizing computed tomography (CT) for initial assessment.
  • Employing magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI) for acute ischemic lesion detection.

  • Performing MR perfusion studies to evaluate brain perfusion.

    • Main Results:

    • CT plays a primary role in acute stroke evaluation.
    • Diffusion-weighted imaging (DWI) effectively visualizes acute ischemic lesions.
    • MR perfusion studies provide crucial information on brain perfusion.

    Conclusions:

    • Optimal MRI protocols involve DWI and perfusion studies for acute stroke.
    • Accurate patient selection for thrombolytic therapy is vital for safety and efficacy.
    • Advanced imaging techniques improve acute stroke management outcomes.
