This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This is a research study for people who have experienced a sudden, spontaneous brain hemorrhage (bleeding in the brain). Researchers want to test whether a specialized imaging procedure called a cerebral DSA can find the exact location where the bleeding is happening. If they can identify where the bleeding is coming from, it could lead to new treatments in the future that stop the bleeding directly at its source.
Brain hemorrhages are serious and often life-threatening. One of the biggest factors that determines whether a patient survives and recovers is whether the bleeding continues to expand. Right now, doctors don't have a reliable way to find the exact source of the bleeding in the first few hours after it happens. This study could help change that by testing a technique that might pinpoint active bleeding sites.

If you qualify and enroll, you will receive one additional specialized imaging procedure called a cerebral DSA (digital subtraction angiography). This is the gold-standard test for visualizing blood vessels in the brain. The procedure involves injecting a contrast dye into blood vessels while taking detailed X-ray images to see exactly where any active bleeding is occurring. This is the only test involved in the study, and it will be done as soon as possible after your diagnosis — ideally within the first 3 hours.
