Tests overview
Because time is a crucial factor during a stroke emergency, and because different types of strokes necessitate different treatments, doctors need to quickly pinpoint the location of a stroke, the type of stroke, and the extent of the damage to make the correct treatment decisions. For example, the physician must differentiate between ischemic strokes (those arising from a blocked blood vessel) and hemorrhagic stokes (bleeding caused by a burst blood vessel) before the appropriate therapy can begin.
Advances in imaging technology can provide physicians with anatomical information that is precise enough to accurately diagnose strokes without actually entering the patient's body. Other techniques that are more invasive allow physicians to view the damage directly.
This section includes information on a variety of noninvasive techniques:
