Cardiac diffusion weighted imaging The MR scan will be performed in a head-first position like the brain scan, the difference however is that the heart will be in the isocentre instead of the brain. Cardiac MR scans are usually cardiac triggered, so we need to attach 4 ECG electrodes (stickers) on the participant's chest which will be then connected to our MR conditional ECG unit. The remaining part is very similar to the brain scan and all the limitations/restrictions that apply to brain MRI such as not having any metallic implant, metallic tattoo, etc. apply to the cardiac MR as well.

Furthering our understanding of Alzheimer and Parkinson's Disease DEPICT (Detailed Exploration of Pathology in Cortical Tissue aims to use Brain imaging (MRI scans) to give us a better understanding of the reasons that some people with Alzheimer’s and Parkinson's disease develop symptoms quicky while in others' symptom change is slower. Understanding these differences is potentially key to the development of more targeted treatments for individual patients. We are looking for healthy adult participants (people without Alzheimer’s or Parkinsons Disease) to act as a control group for the study. You will need to be able to undertake MRI scans of your brain over 2 visits to CUBRIC, 12 months apart. A safety screening check will take place to assess if you are safe to undergo an MRI scan. There will also be some cognitive questionnaires. Start Date: May 1, 2025 4 hours Age Eligibility: 60+ (years) Location: CUBRIC 75 per visit Additional Info

Investigating the role of human brainstem noradrenergic centres in sedation, analgesia and haemodynamic control. You will be asked to visit the Cardiff University Brain Research Imaging Centre on two occasions. First Visit: During the first visit, we will screen you for any contraindications to MRI and conduct a general health assessment. We will provide detailed information about the study tasks, and you will have the opportunity to ask any questions. This visit will last up to 1 hour. Second Visit: During the second visit, you will receive a drug called Dexmedetomidine. First, your brain will be scanned using MRI. Then, while you remain on the MRI bed, you will be administered Dexmedetomidine. The dose will be low and is expected to make you only moderately sleepy. After this, your brain will be scanned again while you are receiving the drug. During the scans, we will measure your brain activity as you perform a series of tasks. These include watching a screen, completing a hand-grip task, and experiencing mild stimulation to your skin (which may be moderately painful). This second visit will last up to 5 hours. You will receive £120 plus travel expenses for your participation. Start Date: June 11, 2025 5 hours Age Eligibility: 18-50 (years) Location: CUBRIC 120 Additional Info
