Damage to the brainstem – the brain’s ‘control centre’ – is behind long-lasting physical and psychiatric effects of severe Covid-19 infection, a study has suggested. Using ultra-high-resolution scanners that can see the living brain in fine detail, researchers from the Universities of Cambridge ... READ MORE

Patient story – Kathryn Hedigan, EXPLAIN study
Kathryn Hedigan took part in the EXPLAIN study, which used hyperpolarised xenon MRI scans to investigate possible lung damage in long COVID patients who had not been hospitalised with COVID-19 but who continued to experience breathlessness. Kathryn, aged 66, lives near Burford in West ... READ MORE
Heart scans could help thousands avoid unnecessary invasive procedure
Thousands of patients admitted to hospital every year with suspected heart attacks could avoid an unnecessary invasive procedure if they have a routine heart MRI scan first, according to new research. The study, funded by the NIHR Oxford Biomedical Research Centre (BRC) and British Heart ... READ MORE
AI analysis of heart scans predicts risk of developing heart problems ten years in advance
A University of Oxford research team has developed an artificial intelligence (AI) technology which can accurately predict the risk of a heart attack, heart failure or cardiac death from routine cardiac CT scans, up to ten years in advance. The study, funded by the British Heart Foundation and ... READ MORE
Study outlines feasibility of multiple disease risk prediction model for primary care
A team of researchers have found that a single, integrated health check carried out in a primary care setting can accurately predict risks for diseases across multiple organs. Currently, GPs are often limited to assessing the risk of diseases one at a time, a process that is ... READ MORE
Study assesses new MRI technique to detect liver cancer
Oxford researchers have been awarded funding to conduct a study comparing a new type of MRI (Magnetic resonance imaging) to standard of care ultrasound for liver cancer surveillance in people with cirrhosis. The University of Oxford’s DeLIVER team, which is investigating early detection methods ... READ MORE
NHS health checks can help to reduce disease rates and mortality, study finds
A University of Oxford study has found that attending an NHS Health Check is associated with a decreased risk of dying and of diseases, such as dementia, heart attack, kidney disease and liver cirrhosis. The results, published in BMC Medicine, suggest that preventative programmes such as ... READ MORE
AI tool could help thousands avoid fatal heart attacks
An AI tool that can predict 10-year risk of deadly heart attacks, could transform treatment for patients who undergo CT scans to investigate chest pain, according to research supported by the NIHR Oxford Biomedical Research Centre (BRC). In the first real-world trial of the AI tool, it was ... READ MORE
Longer-term organ abnormalities confirmed in some post-hospitalised COVID patients
A study looking at the longer-term impact of COVID-19 has found that nearly a third of patients admitted to hospital with COVID-19 displayed abnormalities in multiple organs five months after being discharged. Some of these abnormalities have been shown through previous work to be evidence of ... READ MORE
Blood clots during COVID-19 may cause ongoing cognitive problems
High levels of two proteins at the time of COVID-19 have been found in patients who later experienced cognitive problems, including ‘brain fog'. The findings give a major clue as to one cause of their symptoms: blood clots. Researchers from the University of Oxford looked at blood tests from ... READ MORE
New imaging method trialled for retinal diseases
Clinical scientists in Oxford have presented a new method of imaging of the retina that overcomes many of the drawbacks of the current standard way of diagnosing and monitoring retinal diseases like age-related macular degeneration (AMD). The study, whose findings were published in the journal ... READ MORE
New imaging centre performs first stroke thrombectomy
A new imaging centre at the John Radcliffe Hospital carried out its first stroke thrombectomy. The Acute Multidisciplinary and Interventional Centre (AMIIC) carried out the procedure on 17 May as part of its partnership with Oxford University Hospitals (OUH) NHS Foundation Trust. A ... READ MORE
New tool uses health records to predict risk of developing lung cancer
Researchers from the Universities of Oxford and Nottingham have developed a new tool that can identify the people most at risk of developing lung cancer over the next 10 years, and put them forward for screening tests earlier, saving time, money and, most importantly, lives. The researchers ... READ MORE
New imaging centre officially opened
A new Acute Multidisciplinary Imaging and Interventional Centre (AMIIC), based at the John Radcliffe Hospital, has been officially opened. AMIIC, part of the University of Oxford’s Radcliffe Department of Medicine, was previously known as AVIC (Acute Vascular Imaging Centre). The newly ... READ MORE
Study develops radiotranscriptomic AI analysis to enable virtual heart biopsies
Oxford University researchers have found a new way of directly quantifying vascular inflammation in COVID-19 patients, in a study that could pave the way to more efficient trials of new treatments and identify patients who might be at risk of long-term complications. The study, which was ... READ MORE
Moderate drinking linked to brain changes and cognitive decline
Consumption of seven or more units of alcohol per week is associated with higher levels of iron in the brain, according to a study by Oxford researchers. Accumulation of iron in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a potential mechanism for alcohol-related ... READ MORE
OUH agrees long COVID research collaboration with Polarean
Oxford University Hospitals (OUH) and the medical imaging technology company, Polarean Imaging plc, have entered into a research collaboration to study the long-term effects of COVID-19 in patients who are still experiencing breathlessness months after infection. Polarean produce an ... READ MORE
Review highlights impact of Long COVID on cardiovascular system
The wide-ranging effects of long COVID and the associated issues for healthcare providers have been revealed in a new review of the major studies into the condition, which specifically highlights the impact of long COVID on the cardiovascular system. The review, published in the European Heart ... READ MORE
Lung abnormalities found in long COVID patients with breathlessness
Researchers have identified abnormalities in the lungs of long COVID patients who are experiencing breathlessness that cannot be detected with routine tests.
