ClinConnect Summary

This clinical trial is exploring new ways to create detailed images of blood vessels in the brain, which is important for diagnosing and treating cerebrovascular diseases, like those affecting blood flow to the brain. Participants will undergo two types of scans: a traditional method called 3D-DSA and a new AI-assisted approach to see which one works better and how much radiation each method uses.

To be eligible for this trial, participants must be at least 18 years old and need a specific type of imaging procedure for their condition. They should be able to understand the study and agree to take part by signing a consent form. However, individuals with severe heart or lung issues, those who have had high radiation exposure in the past, or pregnant or breastfeeding women cannot participate. The trial is not yet recruiting, but it promises to help improve how doctors visualize and treat conditions affecting brain blood vessels.
