Plain English Summary

Background and study aims
MRI is an essential part of the diagnostic workup in dementia, however, the time taken and cost limit its availability. Reduction in scan time will solve these issues. This study aims to develop an ultra-fast MRI scan cutting the gold-standard MRI scan from 30 to 7 minutes, with these scans providing non-inferior images to aid in dementia diagnosis.

Who can participate?
Patients referred to the National Hospital for Neurology and Neurosurgery

What does the study involve?
The study involves a standard clinical MRI scan (30 minutes) with an additional 7 minutes for the ultra-fast scan, donation of a blood sample and 10 minutes of neuropsychology

What are the possible benefits and risks of participating?
There is no direct benefit for participating in the study. Some people experience minor discomfort, bruising or swelling following a blood draw. There is also a small risk of developing an infection at the site of blood draw. MRI scans may feel slightly uncomfortable due to the noise the machine makes. The table you lie on may feel hard, and the room may be cool, but the medical team will do everything they can to make you comfortable and blankets may be provided. You may be tired or sore from lying
in one position for a long time. Some people experience claustrophobia when having a scan, but the medical team will do whatever they can to help you relax before and during the scan. The MRI scanner produces loud tapping, knocking, chirping and squeaking sounds during the scans. Before your scan, the technicians will give you disposable foam ear plugs and headphones to wear to protect your hearing from the loud noise. Cognitive testing can be mentally tiring but is unlikely to cause any harm.

Where is the study run from?
National Hospital for Neurology and Neurosurgery (UK)

When is the study starting and how long is it expected to run for?
August 2021 to July 2025

Who is funding the study?
1. Biogen
2. Alzheimer's Society
3. Rosetrees Trust

Study hypothesisThere is overwhelming pressure on healthcare systems to provide wider and more timely access to a dementia diagnosis. Structural MRI scans are an essential part of the diagnostic workup in dementia but their availability is confounded by their price and time taken. Making a substantial reduction in scan time would tackle these issues and mean that MRI would be available to most cases. This study develops an ultra-fast scanning protocol shortening scan time from 30 minutes to 7 minutes without impacting image quality. We will assess the ability of ultra-fast MRI to aid in dementia diagnosis and measure change over time, over short and longer intervals.

ConditionDementia
Intervention170 participants from the cognitive disorders clinic at the National Hospital for Neurology and Neurosurgery (UCLH) will be recruited. These participants are due to have a same-day MRI scan which takes 30 minutes, this study adds an additional 7 minutes in scanning time. They will also be asked to provide a blood sample and undergo a brief neuropsychological examination.

Participants in the longitudinal sub-studies will have the same as above at their first visit, with repeat scanning at subsequent visits, as well as optional blood sample collections.
Intervention typeOther
Primary outcome measureNon-inferiority of ultra-fast MRI compared to gold standard MRI assessed using a 5-point Likert
scale at baseline
Secondary outcome measures1. Stability of ultra-fast MRI compared to gold standard MRI, assessed using a 5-point Likert scale at 2 weeks to 2 months
2. Ability of ultra-fast MRI to track longitudinal change compared to gold standard MRI, assessed using a 5-point Likert scale at 1 year
3. Blood biomarkers assessed by immunoassays at baseline, 2 weeks to 2-month interval and 1-year interval
