Proving Utility of a New Field-cycling MRI Prototype in Acute Stroke Patients

NCT07004140 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 40

No results posted yet for this study

Summary

The goal of this study is to test if a new type of MRI scanner, called Field-Cycling Imaging (FCI), can show changes in the brain within the first day of a stroke due to a blocked blood vessel or bleeding in the brain. The main question it aims to answer is:

• Can FCI identify brain tissue that might recover within the first few hours after a stroke begins?

Participants will undergo a standard MRI scan and an FCI scan, as soon as possible after hospital admission.

Participants who have had a blocked blood vessel will also provide a blood sample and will have a follow up visit at 30 days for repeat of both scans and providing another blood sample.
