PUFFINS Brain Health Study
The PUFFINS Brain Health Study aims to find easier and more affordable ways to spot and keep an eye on brain changes caused by a condition called small vessel disease. This condition is a common cause of strokes and can contribute to memory issues. Currently, special MRI scans are used, but they can be very expensive and not always easy to access for everyone. This study is testing new, lower-cost MRI technologies that use much weaker magnetic fields. Researchers hope these new scanning methods, called field-cycling imaging (FCI) and ultra-low field MRI (ULF-MRI), can accurately detect brain changes linked to small vessel disease. The goal is to develop computer programs to analyse these scans, helping to track how the disease progresses and eventually improve care for people across Scotland.
At a glance
What is this study about?
Small vessel disease is a common condition that affects the tiny blood vessels in your brain. When these small vessels aren't working properly, it can lead to serious problems like strokes, memory loss, and even dementia. Understanding how this disease affects the brain and tracking its progression is really important for developing new treatments and improving care for patients.
Currently, special brain scans called MRIs are the best way to see these changes. However, traditional MRI machines are very expensive to buy and run, and they need a lot of space. This means that not everyone can easily get an MRI scan, especially if they live in remote areas or if many scans are needed over time. This study is trying to solve this problem by looking at new types of MRI scanners that are much cheaper and easier to use.
The PUFFINS study is specifically testing two new approaches: 'field-cycling imaging' (FCI) and 'ultra-low field MRI' (ULF-MRI). These new machines use much weaker magnetic fields, making them more affordable and potentially available to more people. The researchers want to see if these new scans can accurately spot the tiny changes in the brain caused by small vessel disease, just like the more expensive machines. They also want to develop clever computer programs to automatically analyse these new scans, making it quicker and easier to understand what's happening in the brain. The overall goal is to make brain health checks more accessible across the UK.
Key takeaways
- The study aims to improve brain scanning for small vessel disease.
- It's testing new, more affordable MRI technologies.
- Small vessel disease can cause strokes and memory problems.
- Taking part involves several brain scans and thinking tests.
- The goal is to make brain imaging more accessible for everyone.
Who may be eligible?
To be part of this study, you need to be at least 50 years old and not have any problems with your memory. You should also have a diagnosis of small vessel disease, which is a condition affecting the tiny blood vessels in your brain.
There are a few reasons you might not be able to join. For example, if you've had a major stroke in the past (although minor strokes or 'mini-strokes' are usually fine). You also can't take part if you have certain medical devices in your body, like a pacemaker, which would make an MRI scan unsafe. You must also be able to understand and speak English, and be able to give your informed consent, meaning you understand what the study involves and agree to take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 50 years old or older?
- Do you have a diagnosis of small vessel disease?
- Do you feel your memory is generally good?
- Can you understand and speak English well?
- Do you have an implant (e.g., pacemaker) that makes MRI scans unsafe?
What does participation involve?
If you join the study, your involvement will last for a period of time, though the exact duration isn't specified. You will have a few visits that involve different types of brain scans and a chat about your thinking skills. At the beginning (enrolment), you'll have three different research brain scans: a '3T MRI', a 'Field-cycling Imaging' scan, and an 'ultra-low field MRI'. You'll also have an interview to check your memory and thinking. Later on (follow-up), you'll repeat all three types of brain scans and have another memory and thinking interview. The study does not involve taking any new medications.

Common questions
What is small vessel disease?
It's a condition where tiny blood vessels in your brain become narrow or damaged, which can affect how your brain works and lead to strokes or memory issues.
What is an MRI scan?
MRI stands for Magnetic Resonance Imaging. It's a safe scan that uses strong magnets and radio waves to create detailed pictures of the inside of your body, including your brain.
Why are you looking at new types of MRI?
Current MRI machines are expensive and not always easy to access. This study hopes to find cheaper, more widespread ways to scan and monitor brain health related to small vessel disease.
Will I get paid to take part?
The study information doesn't mention payment for participants, but you will often have travel expenses covered. Always check with the study team.
Will I find out my scan results?
Research scans usually aren't shared with participants immediately. If anything medically important is found, the study team will let you know and advise on next steps. Ask the study team for their specific policy.
