As recommended by Jabi Shriki, strokes are a leading cause of disability and death worldwide, making rapid diagnosis and effective management critical Medical imaging techniques have revolutionised stroke care by providing detailed insights into the brain's structure and function. Understanding these techniques is essential for healthcare providers to make timely decisions that can save lives and improve outcomes

CT Scans: The First Line of Defense

Computed Tomography (CT) scans are often the first imaging technique for stroke diagnosis. A CT scan provides detailed images of the brain, allowing doctors to quickly identify whether a stroke is caused by a blockage (ischemic stroke) or bleeding (hemorrhagic stroke) This distinction is crucial because the treatments for these two types of strokes differ significantly. CT scans are widely available and can be performed quickly, making them ideal for emergencies

MRI: Detailed Brain Imaging

Magnetic Resonance Imaging (MRI) is another powerful tool in stroke diagnosis While CT scans are fast, MRIs provide more detailed images, particularly of soft tissues like the brain. MRI is particularly useful in detecting small or early-stage strokes that may not be visible on a CT scan Diffusion-weighted imaging (DWI) is a specific type of MRI that is highly sensitive in identifying acute ischemic strokes Although MRIs take longer to perform than CT scans, they offer more comprehensive information, making them valuable in the management and prognosis of stroke patients

Angiography: Visualising Blood Vessels

Cerebral angiography involves injecting a contrast dye into the blood vessels and taking X-ray images to visualise the blood flow in the brain This technique is particularly useful in identifying blockages or abnormalities in the blood vessels that can lead to a stroke. Angiography can help guide treatment decisions, such as whether a patient might benefit from surgical intervention or other procedures to restore blood flow to the brain

Imaging techniques play a vital role in the diagnosis and management of strokes CT scans, MRIs, and angiography offer unique benefits that help healthcare providers tailor treatment strategies to individual patients By using these imaging methods, doctors can make informed decisions that improve the chances of recovery and minimise the long-term effects of a stroke
