PUFFINS Brain Health Imaging

Proving the Utility of Ultra-low Field MRI for Assessing Brain Health

Observational University of Aberdeen · NCT06947876

This project will try lower-cost low-field, ultra-low-field, and field-cycling MRI scans alongside standard 3T MRI to image the brains of adults aged 50+ with cerebral small vessel disease who do not report memory problems.

What this trial studies

PUFFINS compares novel low-field, ultra-low-field, and field-cycling MRI methods with conventional 3T MRI in people with cerebral small vessel disease. Eligible participants will undergo enrollment and follow-up research scans using each imaging approach at University of Aberdeen imaging sites to compare image quality and detection of SVD features. The goal is to see whether lower-cost, simpler scanners can reliably identify markers of SVD and track changes over time. Results will guide development of more accessible MRI options for diagnosis and monitoring of small vessel disease.

Who should consider this trial

Good fit: Adults aged 50 or older with cerebral small vessel disease (Fazekas score 1–3), who do not report memory problems, can give informed consent, and have no MRI contraindications are ideal candidates.

Not a fit: People with a history of major stroke, those with reported memory loss or dementia, or anyone with contraindications to MRI (for example implantable cardiac devices) are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this work could make brain imaging for small vessel disease much cheaper and more widely available, enabling earlier detection and better monitoring of progression.

How similar studies have performed: Early research on low-field MRI and field-cycling imaging has shown promise for some brain applications, but these techniques remain relatively novel and are not yet established in routine clinical practice.
