Brain Imaging

588
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

    Area of Science:

    • Neurology
    • Radiology
    • Emergency Medicine

    Background:

    • Acute stroke management has evolved with new treatments like endovascular thrombectomy and extended IV thrombolysis windows.
    • The principle 'time is brain' emphasizes the need for rapid and accurate diagnostic tools.

    Purpose of the Study:

    • To outline the role of medical imaging in the diagnosis, prognosis, and timely treatment decisions for acute stroke patients.
    • To highlight the paradigm shift in imaging utilization for acute stroke care.

    Main Methods:

    • Computed tomography (CT) has become the primary imaging modality.
    • CT angiography (CTA) is vital for detecting large vessel occlusions.
    • CT perfusion (CTP) aids in predicting tissue fate and selecting patients for therapy.

    Main Results:

    • Advances in stroke treatment necessitate rapid, reliable, and round-the-clock imaging availability.
    • CTA is essential for identifying candidates for endovascular thrombectomy.
    • Collateral imaging on CTA and CTP are valuable tools for patient selection in acute stroke therapy.

    Conclusions:

    • Modern imaging of the brain and its vasculature is fundamental to understanding acute stroke pathophysiology.
    • Timely and appropriate clinical decisions in acute stroke rely heavily on advanced imaging techniques.
