Covid-19 causes characteristic changes in lung tissue visible in CT scans and chest radiographs, known as “ground-glass” opacities. Imaging is now considered a valid alternative, possibly even superior to RT-PCR. ‘This sparked an international debate about the role of CT in the diagnostic work-up of Covid-19,’ said radiologist Professor Cornelia Schäfer-Prokop.
RSNA 2020: International experts showcased new studies on chest CT’s role in Covid-19 diagnosis and treatment. A staggering volume of work and has been produced on the pandemic this year, with an average 367 Covid-19 journal articles published per week, according to Michael Chung, Assistant professor of radiology at Icahn School of Medicine at Mount Sinai, NYC.
Low, light and with a field strength: 0.55-tesla with added new digital technologies. Indeed, this is a very new class of MRI scanner created by Siemens Healthineers. We interviewed Christiane Bernhardt, Vice President of Magnetic Resonance Marketing & Sales, Business Line MR, at Siemens Healthineers, about the technologies behind this development, plus its advantages and applications.
Chronic illnesses can have a dramatic impact on a patient's later life. An early diagnosis of such diseases opens up the possibility of taking medical action in good time.
Wearable ultrasound sensors can help patients monitor their lung health from their own homes. The potential application of this technology were outlined in a session at MEDICA 2020.
Costantino Balestra, Professor of Physiology at Haute Ecole Bruxelles-Brabant in Belgium, uses point-of-care ultrasound (POCUS) in environments that could not be more different from a typical hospital setting. His expertise lies in studying the effects of extreme conditions on the human body, including temperatures, altitudes, and ambient pressures, for example, in deep oceans. One of his areas…
‘Mini-lungs’ grown from tissue donated to Cambridge hospitals has provided a team of scientists from South Korea and the UK with important insights into how COVID-19 damages the lungs. Writing in the journal Cell Stem Cell, the researchers detail the mechanisms underlying SARS-CoV-2 infection and the early innate immune response in the lungs.
Scientists at EPFL are using technology to better understand how coronavirus causes blood clots in some patients. They have developed a simplified model of a lung that lets them observe, for the first time, how the virus attacks the cells lining blood vessels.
Scientists have unearthed a possible link between the severity of COVID-19 and air quality. The preliminary study – looking at whether areas with higher levels of air pollutants in England are associated with a larger number of cases/deaths from COVID-19 – was conducted by a team from the University of Cambridge. Aware of the effects that air pollutants have on human health – and that…
Around 550 million people have chronic obstructive pulmonary disease (COPD), according to two University of Manchester medical students. The figure more than doubles the previous estimate of 251 million people with the illness linked to smoking by the World Health Organization (WHO) Global Burden of Disease Study. The University of Manchester students, Emily Hammond and Charles McDonald, made the…
A recent preprint study in France underpins the debate on whether lung ultrasound (LUS) should be used to triage COVID-19 patients better at the hospital as well as in primary care. The eChoVid study, published as a preliminary report of work on medTrix, shows that LUS enables identification of lung lesions as well as chest CT in COVID-19 patients. A team of French researchers compared routinely…
COVID-19 patients can suffer long-term lung and heart damage but, for many, this tends to improve over time, according to the first, prospective follow-up of patients infected with the coronavirus, presented at the European Respiratory Society International Congress. [1]
Babies born with higher levels of cadmium in their umbilical cord blood may be more likely to develop childhood asthma and allergies, according to research presented at the European Respiratory Society International Congress. (1)
Researchers at the University of Notre Dame are developing a new technique using artificial intelligence (AI) that would improve CT screening to more quickly identify patients with the coronavirus. The new technique will reduce the burden on the radiologists tasked with screening each image. Testing challenges have led to an influx of patients hospitalized with COVID-19 requiring CT scans which…
The SARS CoV-2 virus which causes COVID-19 may have been named prematurely. As more has become known about the infection, the severe disease does not appear to be a respiratory syndrome at all. Patients who only have a respiratory illness tend not to have a severe condition, while patients who develop a severe condition tend to have non-respiratory conditions, primarily thrombotic or hyper-immune…
There are major complications from COVID-19 – ARDS, pulmonary embolism and neurological – that imaging can help detect, manage and/or follow up in the long term, radiologists from France and the UK explained during a recent ESR Connect session. ARDS is the most dreaded complication and the number one morbidity in COVID-19 patients. The incidence was up to 30% of patients in initial reports.…
Voice analysis by a smartphone app identifies lung congestion in heart failure patients, allowing early intervention before their condition deteriorates. The small study is presented on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC). “Speech is personal and as such, very small changes (related to the same person) can be detected – for example, the ability…
Benchtop tools for studying the respiratory system misrepresent the interdependence between the diaphragm, abdomen and lungs. Meanwhile, computational models often hide the mechanisms in a black box computation, without a clear picture of what transpires in the process. This means students form a poor understanding of respiratory mechanisms and makes it hard to train clinicians for real scenarios…
New research suggests that cigarette smoke spurs the lungs to make more ACE2 (angiotensin-converting enzyme 2), the protein that the coronavirus responsible for COVID-19 grabs and uses to enter human cells. The findings, reported in the journal Developmental Cell, may explain why smokers appear to be particularly vulnerable to severe infections. The analysis also indicates that the change is…
The novel Coronavirus infection (severe acute respiratory syndrome SARS-CoV-2), which has led to the spread of COVID-19 around the world, has upset normal workflow in hospitals. The increased workload and stress, due to the necessity of implementing safe and separate diagnostic pathways, and the need to constantly monitor the development of the disease after its onset, continues to have a…
Establishing whether a patient is suffering from severe lung disease, possibly COVID-19, within a few minutes: this is possible using fairly simple ultrasound machines that are enhanced with artificial intelligence. A research team at Eindhoven University of Technology (TU/e) and the University of Trento in Italy has been able to translate the expertise of top lung specialists into a software…
Although the clinical symptoms of new pediatric lung disorders such as severe acute respiratory syndrome (SARS), swine-origin influenza A (H1N1), Middle East respiratory syndrome (MERS), e-cigarette or vaping product use-associated lung injury (EVALI), and coronavirus disease (COVID-19) pneumonia may be nonspecific, some characteristic imaging findings "have emerged or are currently…
As the coronavirus spreads and infections with Covid-19 further increase throughout Europe, ECMO therapy turns out to be a necessary option for patients with severe courses. Xenios AG provides ECMO consoles that can be used for the treatment of patients who develop severe pneumonia and ARDS with lung failure which also might result from infection with the coronavirus.
Coronavirus can be identified automatically from sick patients’ lung X-rays using artificial intelligence (AI) developed at Brunel University London.
Hospitals and organizations worldwide joined forces with AI imaging company icometrix in a global initiative to leverage artificial intelligence (AI) in the fight against COVID-19. The multinational collaboration resulted in the development of an AI algorithm, icolung, which received CE-marking for clinical use in Europe. icolung is the first CE-marked AI solution for CT resulting from a…
