Radiological Research Trust

The Radiological Research Trust was registered with the Charity Commission (registration number 292828) in October 1985. The Trust was set up to raise funds and distribute grants for research and education in Medical Imaging, in response to the severe lack of funding for such a key medical field as radiology. Suggestions of how you can support us generally are available on our Support Us page. The Radiological Research Trust is a National Institute for Health Research (NIHR) non-commercial partner organisation. Details of the NIHR can be found at

The Radiological Research Trust is offering small research grants for early career researchers in medical imaging of up to £5,000 awarded biannually.

The next grant deadline is TBA 2024 – see Grants page for details on how to apply

Dr T. Ratneswaren (2024). COVID-19 Stroke Apical Lung Examination Study 2: a national prospective CTA biomarker study of the lung apices, in patients presenting with suspected acute stroke (COVID SALES 2)

‘The COVID-SALES 2 study is the follow-up to the landmark first COVID-SALES study (published in 2020). Undertaken in collaboration with the Radiology Academic Network for Trainees (RADIANT), this prospective multicentre study expanded on the scope of the first study, with data collected from 13 UK hyperacute stroke units. The findings have reinforced the clinical utility of lung apical changes on routine CT angiography studies in the incidental diagnosis of COVID-19.’ Jason Mak, Clinical Radiology SpR, RADIANT Co-chair.

‘In summary, we recommend routinely analysing lung apices in patients with stroke undergoing carotid CTA, because this rapid and easy assessment of apices is valuable, opportunistic, and “free” information in a routine and unmodified scan. The apical analysis simply identifies patients likely to have COVID-19 with early downstream benefits such as limiting disease transmission.’ Dr Thomas Booth, Reader in Neuroimaging, School of Biomedical Engineering & Imaging Sciences

This study was partly funded by RRT

Dr. Nathan Chan (2020):  ‘COVID-19 Stroke Apical Lung Examination prospective validation Study: A Diagnostic and Prognostic Imaging Biomarker in Suspected Acute Stroke (COVID SALES)’

On behalf of the Radiology Academic Network for Trainees (RADIANT) and the COVID-19 stroke apical lung examination study (COVID SALES) team including Dr Tom Booth, Dr Tarini Ratneswaren and Mr John Aeron-Thomas, I would like to thank the Radiological Research Trust (RRT) for their most generous contribution to our work. Apical lung changes on CT angiography suggestive of COVID-19, have been shown to be a promising diagnostic and prognostic biomarker. The aim of this study was to test this in different centres across the UK. The biomarker is free information obtained opportunistically from a routine urgent stroke scan. It is available very early on in the patient pathway well before SARS COV-2 PCR test results are ready and will contribute to better management of acute stroke patients. 

Dr. Orestis Katsamenis (2020):  ‘Pathogenesis of lethal respiratory COVID-19; 3D X-ray histology imaging of pathology wax blocks’

I am beamline scientist and a clinical applications lead at the μ-VIS X-ray Imaging Centre ( at the University of Southamtpon running the 3D X-ray Histology facility. In 2020 I was awarded a seed funding from the Radiological Research Trust (RRT) to study the pathogenesis of lethal respiratory COVID-19 by means of a novel high-resolution X-ray CT imaging modality that allows non-destructive 3D imaging of tissue biopsies. The technique, a.k.a 3D X-ray Histology ( was developed at University of Southamtpon and I have been working on its development since c. 2015. The RRT funding was pivotal as it allowed us to overcome the primary cost-related obstacles associated with sample preparation, imaging cost, international shipments, and other consumables and allowed me to bring together a multidisciplinary team of experts from the University of Southamtpon, UK and Erasmus University Medical Center, NL, and kick-start the project. Together, we study the pathogenesis of micro-thrombotic events caused by the SARS-CoV-2 infection in the lungs and develop semi-automated AI-based workflow that allows crosstalk of conventional 2D histology and 3D X-ray Histology, shining new light to the damage caused by COVID-19. Importantly, with appropriate optimisation, the same workflow can be applied for the study and/or characterisation of other pathologies beyond COVID-19. RRT support has been vital in allowing me to establish a long-lasting international collaboration, diffuse UK-developed technology to European partners and equally “bring in” expertise from one of the best Pathology centres in EU.

Dr. Haris Shuaib (2019):  ‘Improving treatment of glioblastoma: differentiating progression from pseudo progression’

The grant I received from the Radiological Research Trust was pivotal in launching my PhD work, which has grown to be the largest prospective trial applying machine learning to high grade brain tumours in the UK. The funding allowed me to purchase a GPU-powered machine that was used to develop a machine learning algorithm that can differentiate progression from pseudo-progression in glioblastoma patients. This, alongside the eligibility for CRN support through NIHR portfolio adoption, allowed me to accelerate towards a prospective trial, which is now also supported by an NIHR Doctoral Research Fellowship.

Naomi Sakai (2018):  ‘Technical validation of a novel MRI technique for quantificaiton of bone mineral density’

I received a grant from the RRT in 2018 for technical validation of a new MRI technique to measure bone mineral density whilst I was doing a PhD during time out of my clinical radiology training. The grant enabled me to start a small project, developing and scanning a new imaging phantom and scanning volunteer patients. This work was eventually included in my PhD thesis (even though the idea didn’t exist at the start of my PhD, which just demonstrates how PhD theses can evolve) and I was able to present it at an international imaging meeting (ISMRM 2019, Montreal). I am currently taking another break from my clinical radiology training (on maternity leave) and will be taking up an academic clinical lecturer post on my return. The grant I received undoubtedly helped me progress in my academic career, giving me experience of applying for funding and also enabling me to bring an initial idea to reality. I would encourage researchers with an idea to apply as both the application process and ability move the project forward have been beneficial.

Dr. Rosalind Pratt (2017):  ‘Advanced MRI for the assessment of placental function in Fetal Growth Restriction’

My research aims to discover whether a safe medical imaging technology (Magnetic Resonance Imaging (MRI)) can be developed to assess how well the placenta is working during pregnancy.Placental insufficiency is a condition where the placenta cannot meet the oxygen and nutritional demands of a growing baby in the womb. This is responsible for over a third of stillbirths in the UK. It is also associated with long term health problems for the baby, including cerebral palsy due to brain injury from low oxygen levels. The mother can suffer from high blood pressure and a life-threatening condition called pre-eclampsia.The research grant I received from RRT helped fund the development of a computational MRI model of placental function that estimates the level of oxygen in the baby’s blood. Using this model we investigated blood oxygen levels in pregnancies with small babies compared to normally grown babies, and found they were significantly lower. I am now an NIHR funded Clinical Lecturer in Fetal Medicine at UCL/UCLH, where I am continuing this important research. I have several grants that are funding a larger study to further investigate the use of MRI to assess placental function. The long-term aim of this research is to establish an effective MRI test of placental function for routine use in clinical practice.

MRI reveals differences in feto-placental oxygen saturation between normal and FGR pregnancy that is associated with disease severity


Seed funding from the RRT was instrumental in supporting my early career research, providing me with the opportunity to explore new independently generated research ideas and concepts.  The application of super-resolution reconstruction to MRCP yielded one of the most downloaded papers from Magnetic Resonance in Medicine in 2019 and has allowed me to secure substantial further funding from CRUK for ongoing research evaluating the clinical application of this technology to pancreatic cancer.

What is Radiology?

Radiology is a specialty of medicine that just about everybody in their life uses at some point. If you have ever broken a bone, had a baby, found a lump that has been investigated for cancerous cells or your child as swallowed something horrible you will have used radiological related equipment and expertise.

Radiology has been used for medical purposes for over a century and remains a cornerstone of medicine. It can be used for not only diagnostic but also therapeutic purposes. Physicians use the information gained through radiological imaging to diagnose, treat and monitor injuries and diseases.

Radiology is critical to advances in medicine and therefore ultimately the care which hospitals can provide you, their patients. Radiologists use a wide range of methods to study the body including Ultrasound (US), X-Ray Computed Tomography (|CT) and Magnetic Resonance Imaging (MRI) as seen in the images on the right.

Today the aims of the Trust remain steadfast in providing critical funding to such an important specialty of medicine. Demand for funding remains high and the Trust remains committed to supporting some of the most exciting research in the field.
