3. Magnetic Resonance Imaging and Angiography (MRI and MRA): An MRI takes a specialized picture of the brain (MRI) and its vessels (MRA). Instead of using x-rays, powerful magnetic beams are used to generate the picture. The picture of the brain is more detailed than that obtained by a CT scanner but an MRI also takes longer to obtain. Due to its high level of sensitivity, MRI is considered especially useful when there is doubt regarding time of onset or diagnosis. The technology involves use of a strong magnetic field, and is performed in a special room free of metallic equipment.

Digital subtraction Angiography (DSA)

We have one of the best endovascular biplane DSA labs in the World, which makes us leader in treating vascular disorders of the brain including brain attack. If a patient comes to us after 3 hours of window period but before 12 hours, he can still be treated by injecting drug directly in the clot or retrieving it mechanically. This technique is also very effective if a major blood vessel is blocked where conventional intravenous thrombolytic therapy (as discussed below) is not that effective.
