AI with swarm intelligence to analyse medical data

Communities benefit from sharing knowledge and experience among their members. Following a similar principle - called “swarm learning” - an international research team has trained artificial intelligence algorithms to detect blood cancer, lung diseases and Covid-19 in data stored in a decentralized fashion. This approach has advantage over conventional methods since it inherently provides…

Chest CT illuminates COPD mortality risk

Body composition information derived from routine chest CTs can provide important information on the overall health of people with chronic obstructive pulmonary disease (COPD), including their risk of all-cause mortality. This is the result of a new study, published in Radiology. COPD is a group of chronic, progressive lung diseases that affect about 30 million people in the United States alone.…

AI-powered Covid-19 solution reduces report turnaround time by 30%

The results of a large-scale study indicate that the introduction of an AI-powered solution by healthcare software company Radlogics into radiology workflow to analyze Chest-CT scans during the Covid-19 pandemic reduced report turnaround time by an average of 30 percent, which is equivalent to 7 minutes per case.

Better detection and diagnosis of fungal infections

Beta-glucan tests are proving to be pivotal in the better detection and diagnosis of fungal infections. As a robust complimentary test for traditional testing techniques and biomarkers, it is helping clinicians deliver rapid results and offering greater reassurance in more accurately identifying such infections. β-glucan testing, which is an in vitro diagnostic test, is regularly used at…

AI lung scan analysis rolled out across Europe

The Belgian initiative icovid, which supports radiologists in the assessment of CT images of the lungs of COVID-19 patients, has grown into a multicentre European project, co-funded by the EU Horizon 2020 programme. Icovid was set up in March by UZ Brussel, KU Leuven, icometrix and ETRO, an imec research group of VUB.

Protecting lungs from ventilation-induced injury

An unfortunate truth about the use of mechanical ventilation to save the lives of patients in respiratory distress is that the pressure used to inflate the lungs is likely to cause further lung damage. In a new study, scientists identified a molecule that is produced by immune cells during mechanical ventilation to try to decrease inflammation, but isn’t able to completely prevent…

Covid-19 pneumonia: not your typical garden-variety pneumonia

Bacteria or viruses like influenza that cause pneumonia can spread across large regions of the lung within hours. In the modern intensive care unit, these bacteria or viruses are usually controlled either by antibiotics or by the body’s immune system within the first few days of the illness. But in a study published in Nature, investigators at Northwestern Medicine show Covid-19 pneumonia is…

New insight on severe virus attacks on the lungs

In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study, which was published in Immunity, may contribute to future treatments for Covid-19, among other diseases.

Covid-19: Is CT more sensitive than PCR testing?

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.
