How does imaging technology help diagnose stroke?

Advances in imaging technology have enabled doctors to diagnose a stroke with greater precision than ever before. The more precise the diagnosis, the better the treatment. With improved imaging devices, doctors can also rule out brain tumors, head trauma, abscesses, and other conditions that can mimic a stroke.

Computed tomography, computed tomography angiography, magnetic resonance imaging, magnetic resonance angiography, and Doppler ultrasound all can reveal within minutes whether a stroke is ischemic or hemorrhagic and what caused it. Imaging data can also help determine the evolution, extent, and location of any brain damage and show an obstruction in the artery supplying blood to the involved parts of the brain.

Physicians often repeat imaging tests several days after the onset of a stroke to survey the extent of damage. If your condition gets worse, imaging tests can show areas of the brain that have deteriorated since the previous images were taken.
