Incidental findings

Abnormalities can show up on scans taken for research during the scanning process. Most of these are no cause for concern. But, if the radiographer does happen to notice a potentially serious abnormality while taking the scans, they will refer the scans after your visit to a specialist doctor (radiologist) for review. If the radiologist agrees that the abnormality is potentially serious we will write to you and your GP to tell you.


“Lovely staff and a pleasant environment, which made everything very easy to do and understand.”
“The staff were all wonderful and put me at ease immediately when I arrived at the centre. Nothing was too much trouble and I felt that I had arrived at a second home."
“Fascinating day - and have been very happy to help.”
"Everybody was extremely professional and proficient in their duties and a credit to the organisation.”

Temporary closure of UK Biobank imaging centres

03 Mar 2020

In light of the uncertainty and current concerns about coronavirus (COVID-19), UK Biobank is temporarily closing its imaging centres in Bristol, Reading, Cheadle and Newcastle. Imaging centres scan up to 18 people a day, to create a valuable resource for health research. They will re-open when the situation improves. At that point, we will make contact with participants and re-book their appointment. Staff will continue to be paid while the centres are closed. Some participants have already decided to cancel their appointments.

Professor Rory Collins, UK Biobank Principal Investigator, said: “We are very grateful for the support of our participants in this project. Many fall into a somewhat older age group and may be more vulnerable to the impact of coronavirus. Their health and safety is our main concern, and we feel it is better to be cautious and take pre-emptive action.”​

Lesley Bigwood first participant scanned at Bristol assessment centre
Bristol contributes to world’s biggest and most detailed scanning project

21 Feb 2020

Volunteers are putting their best foot forward for health research as we open our new assessment centre in Bristol. 

The new centre in Patchway will support the work of three other centres across the country. The multi-organ scans will be analysed alongside the vast data already collected from volunteers and will transform the way scientists study life-threatening illnesses.

Professor Naomi Allen, UK Biobank’s Chief Scientist, said:

“What makes this project truly transformational is the opportunity to combine the rich imaging data with the wealth of other information already available or being collected from participants – including their genetics, lifestyle and cognitive function.”

Around 43,000 volunteers from Bristol and surrounding areas contributed to the first phase of the UK Biobank project in 2008. They attended an assessment centre in central Bristol where they were weighed, measured, answered lots of questions about their health and provided a blood sample for genetic analysis.

This new assessment is the biggest collection of scans ever undertaken and nearly 50,000 volunteers have already undergone the four hours assessment at centres in Reading, Cheadle and Newcastle.

MRI assessments of heart chambers will provide an insight to how the heart changes as it pumps blood around the body whilst the abdomen scan will show how fat is distributed in areas like the liver and pancreas. Brain scans will map major connections of neurons and dual-energy X-ray absorptiometry measures bone density throughout the body. Ultrasound assessments of two major arteries that run either side of the neck to the brain will also take place.

Professor Nicholas Timpson, principal investigator of Bristol’s Children of the 90s health study, said:

“In Bristol, we are privileged to have a group of dedicated participants who contribute to both UK Biobank and the Children of the 90s, two studies in one city capturing invaluable information about the health of the general population.

“The UK Biobank imaging study is nothing short of unique in its contribution to health research. At the Children of the 90s, we fully support this effort and would like to encourage any of our original study parents (some of whom are also in UK Biobank) to take part. The generosity and commitment of participants in both studies is extraordinary – please keep going!”

The opportunity to take part in the scanning study is open to existing UK Biobank participants only. If you would like further information please call the Participant Resource Centre on 0800 0276 276

Biobank 2019 mri room low res
Imaging project sees its 30,000th volunteer in Stockport

12 Dec 2019

UK Biobank is nearly halfway to its goal of collating 100,000 scans of vital organs to form the world’s largest collection. A Shrewsbury resident became the 30,000th volunteer on Wednesday at the Stockport assessment centre, which supports the work of two other scanning centres. These high quality pictures of hearts, brains, bones and abdomens will be used by scientists to discover why some people develop life-threatening diseases and others do not.

Ms. Lesley Milne, 72, travelled nearly two hours to the assessment centre in greater Manchester. She said:

“Seeing how it’s making huge leaps to improve healthcare for our future generations is the biggest reward anyone could get. I’m so proud to be part of this project!”

Over 38,000 volunteers from Manchester took part in the initial assessment between 2006 and 2013. These participants are being invited for imaging scans of their heart, brain, bones, abdomen and main arteries. Approved scientists use this information to understand how genes, environment and lifestyle choices lead to certain diseases.

Professor Naomi Allen, UK Biobank’s Chief Scientist, said:

“An imaging resource of this scale is unparalleled in the world of health research, and we’re not even halfway through the project. Combining the wealth of information already available from our 500,000 participants – which includes data on lifestyle and genetic factors – with these powerful imaging data will help transform the health of future populations.”

The imaging data allows for a wide range of studies on illnesses like dementia, stroke, heart disease and weakening of the bones and frailty in later life. Researchers will use findings to help discover new ways of treating and preventing these conditions.

“UK Biobank has been truly transformative in the way that research into common diseases is conducted. The breadth and depth of the available data is simply staggering. This accelerates the speed and clinical impact of new discoveries for population benefit… it’s simply amazing!”

Professor Martin Rutter, Professor of Cardiometabolic Medicine and Honorary Consultant Physician at Manchester University

The assessment centres in Newcastle and Reading support the work of the main scanning centre in Stockport which have scanned almost 20,000 participants between them. A new centre in Bristol will be open next year to further support the project.

Bristol partaking in the world’s biggest imaging project

12 Nov 2019

Final steps have been taken preparing for thousands of people in and around Bristol to undergo detailed imaging as part of the world’s largest scanning project.

Two magnetic resonance imaging (MRI) scanners, weighing 7 and 5 tons, have been delivered to the purpose built facility in the Patchway area. These will obtain images of participant’s brains, hearts, bones and blood vessels. Building work is nearing completion on the multi-million pound imaging centre which is set to open in the New Year. This is a major enhancement of the UK Biobank project and the biggest of its kind.

UK Biobank recruited 43,000 volunteer participants from the Bristol area in July 2008. Participants agreed to have their health followed to help find out why some people get painful and life threatening diseases, including dementia and cancer, whilst others do not.

“This next phase of the UK Biobank project is the biggest and boldest yet. The project aims to image 100,000 of its half a million volunteers and nearly 50,000 have already been through the procedure in Reading, Manchester and Newcastle.

Adding this detailed extra information from images will help in many ways. For instance, it should identify early changes that increase the risk of developing disease, and it may suggest new ways to slow that process, or to prevent disease altogether.”

Professor Rory Collins, UK Biobank Principal Investigator 

It is hoped that UK Biobank participants, who first volunteered for the project around 11 years ago, will help again to create the most detailed study of its kind ever undertaken. The first participants at the Bristol site are due to be scanned in the early months of next year, with thousands more to follow.
