ClinConnect Summary

This clinical trial is looking at a new type of imaging test for patients with cerebrovascular diseases, which are conditions that affect the blood vessels in the brain. The study aims to create a "one-stop" CT examination that combines three different imaging techniques into one visit. This will help doctors better understand issues like blockages or narrowing of blood vessels, brain aneurysms, and other related diseases. The goal is to improve diagnosis and treatment for patients experiencing strokes or other brain-related issues.

To participate in this trial, you need to be between 18 and 100 years old and have certain conditions like artery blockages or brain aneurysms. However, there are some people who won't be eligible, such as those with severe kidney or liver problems, or those who are pregnant. If you qualify and decide to join the study, you would undergo the CT scans and provide some clinical information about your health. It’s important to note that participation is voluntary, and you will be asked to sign consent forms to ensure you understand the process. This trial is not yet recruiting participants, but it aims to help improve care for patients with cerebrovascular diseases in the future.
