Also, in the first 6 hours after a stroke, it can be hard to confirm an ischemic stroke via CT.Īfter an initial CT scan to rule out other causes of symptoms, a doctor may order an MRI to obtain more information. However, a CT scan does not provide the same level of detail as an MRI.įor example, a doctor cannot always see the site of an ischemic stroke on a CT scan. Will a stroke always show up on a CT?Ī CT scan is excellent for ruling out a hemorrhagic stroke or other causes for a person’s symptoms, such as a tumor. There may be changes in the volume of brain cells where the stroke took place. Yes – like an MRI, a CT scan can detect old strokes. For example, a 2019 study suggests that finding out more information about the size and location of the blood clot in ischemic stroke is worth the extra minutes an MRI takes. Some research supports using an MRI first, rather than a CT scan. However, they can rule out a hemorrhagic stroke and other potential causes for the person’s symptoms. Both CT or MRI scans can identify the stroke type, but CT scans cannot always find the location of a blood clot. A CT scan does not provide as much detail as an MRI, but it gives doctors enough information to move forward.Īfter someone has a stroke, the priority is to diagnose the type of stroke so the person can receive the right treatment. CT scanners tend to be more widely available in hospitals than MRI machines, and a CT scan takes less time than an MRI.īecause of this, many doctors still consider CT scans their first choice for urgent imaging. A CT scan is another type of medical imaging test that doctors can use to diagnose stroke.
