Finding the right blocked artery in stroke using CT scans

This trial compares MRI and CT scans to see which is better at diagnosing a severe stroke caused by a large blocked artery. If you have had stroke symptoms for less than 6 hours and are eligible for either scan, you may help doctors choose the best test for future patients.

This study compares two types of clot/brain-bleeding risk imaging scans to see which better predicts recovery in people with ischemic stroke. If you qualify and get the right timing and scan results, the trial may help doctors choose the best way to predict your prognosis.

This study looks at blood markers and brain/artery scan results to predict who with intracranial artery narrowing is more likely to have another stroke. It may help doctors spot higher-risk people earlier and better target prevention.

This study uses advanced CT scans to get a better look at bleeding in the brain (hemorrhagic stroke). It may help doctors understand the stroke and guide care.

This trial studies a way to sort and treat people with a specific type of acute ischemic stroke (caused by a blockage in a large brain artery). It may help doctors choose the best next steps—either a procedure or medication—faster and more appropriately.

This trial tests if a special heart CT scan can find the cause of a stroke. If you have a moderate to severe stroke and a blocked artery in your brain, this scan might help doctors understand why it happened.
