07/08/2020As COVID-19 cases in the United States continue to surge, there is an ongoing search for quick and reliable testing. Though there are conflicting opinions on using chest computerized tomography (CT) scans as a method of screening in the United States, the technology has been successfully used to identify the disease in other parts of the world.
20/07/2020A luminescent fluid that allows more accurate observation of different areas of the organism has been developed by a research team from the Colloidal Materials group of the Institute of Materials Science of Seville in collaboration with the Institute of Materials Science of Aragon, the Andalusian Centre of Medicine and Biotechnology and the Spanish National Accelerator Centre.
15/07/2020An open-access American Journal of Roentgenology (AJR) article investigating the differences in CT findings between coronavirus disease (COVID-19) pneumonia and influenza virus pneumonia found that most lesions from COVID-19 were located in the peripheral zone and close to the pleura, whereas influenza virus was more prone to show mucoid impaction and pleural effusion.
11/06/2020An algorithm that analyses MRI images and automatically detects small changes in knee joints over time could be used in the development of new treatments for arthritis. A team of engineers, radiologists and physicians, developed the algorithm, which builds a three-dimensional model of an individual's knee joint in order to map where arthritis is affecting the knee.
02/06/2020Largest case series (n=30) to date yields high frequency (77%) of negative chest CT findings among pediatric patients (10 months-18 years) with COVID-19, while also suggesting common findings in subset of children with positive CT findings.
27/05/2020Researchers at the University of Zurich have developed a new X-ray contrast agent. The contrast agent is easier to use and distributes into all blood vessels more reliably, increasing the precision of vascular imaging. This reduces the number of animals required in research experiments.
21/05/2020The organ of balance in the inner ear is surrounded by the hardest bone in the body. Using synchrotron X-rays, researchers at Uppsala University have discovered a drainage system that may be assumed to play a major role in the onset of Ménière's disease, a common and troublesome disorder. These results are published in the journal Scientific Reports.
01/10/2019Pneumonia, COPD or cystic fibrosis – people with such lung diseases have to consult their doctor regularly. Little children have to undergo certain measurements by the doctor, too. In order to save people`s need to visit a doctor, telemedicine offers many ways to do examinations at home.
02/09/2019Artificial intelligence is no longer a dream of the future in medicine. Many studies and initial application examples show that it sometimes achieves better results than human physicians. At Jena University Hospital, the work with AI is already lived practice. It is the first institution in the world to use algorithms in radiological routine to reconstruct CT images.
02/09/2019In modern medicine, especially in the field of imaging, huge amounts of data are produced – so much that radiologists can hardly keep up with diagnosing the images. Artificial Intelligence could be the solution to this problem. But how exactly can it help in this task? How can man and machine work together? And what else will be possible in the future with the support of intelligent systems?
02/09/2019More patients, more examinations, more CT images – in radiology there is too much work for too few physicians. CT scans are evaluated in the shortest possible time, which leads to anomalies being overlooked. Artificial intelligence, on the other hand, works with constant speed and performance, which is why radiological routine increasingly relies on its support.
02/09/2019Radiology is a field that produces large volumes of data, which can no longer be managed without the help of intelligent systems. This is especially true when it comes to the interpretation of medical images. While this takes physicians years of training and experience, several hours of work and the highest level of concentration, AI only requires a few seconds to accomplish the same task.
08/04/2019Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.
01/04/2019In an ischaemic stroke, rapid treatment is essential. In this moment good imaging data is particularly important to enable doctors to make the best possible decision for therapy. Modern CT scanners are increasingly being used to assess stroke patients because they can show the blood flow to the brain over time.
01/04/2019All information from our body and the environment converges in our brain and is transformed into reactions in milliseconds. It is essential for medicine and research to know what our switching centre looks like. Functional methods are used to observe it more closely during work.
01/04/2019Our brain is the command center of our body. This is where all information and impressions are collected and converted into responses and movements. Modern imaging techniques offer physicians and researchers unique insights into the actions of the human central nervous system. The functional imaging technique allows them to watch our brain in action.
25/01/2019CT scan, MRI or X-ray: All these methods allow doctors to see inside the body - including inside the lungs - and make a diagnosis. The clinic for Nuclear Medicine at the RWTH Aachen University Hospital uses a state-of-the-art gamma camera that combines SPECT and CT.
14/11/2018Whether CT, MRT, X-rays or ultrasound – imaging methods provide insights into the human body and are irreplaceable for diagnostics. They are part of everyday hospital life since a long time, but what is currently happening in this field? We took a look – at MEDICA 2018.
02/11/2018It’s safe to say that patients and their prompt medical care take center stage at any hospital. Digitization of the healthcare sector is quickly advancing to make this a reality: data is stored in a digital medium, devices are linked together. But how safe are hospitals in the age of innovation?
02/11/2018It's time: the world's largest medical trade fair opens its doors from 12 to 15 November. More than 5,000 international exhibitors will present their new innovative products and applications. Frums, conferences and special shows will feature exciting specialist lectures and discussions that will give you an insight into electromedicine, laboratory medicine, medical technology and diagnostics.
05/10/2018Many people have damaged or suboptimally functioning lungs. An accurate diagnosis and subsequent treatment are vital to protect this life-sustaining organ. Modern imaging solutions help physicians and patients understand what happens inside the lungs.
01/10/2018A look inside the lungs is a time-consuming process. To identify the boundaries of the respiratory organ from surrounding other organs, tissues, and structures requires between 200 and 500 computed tomographic images and subsequent manual markings – an elaborate process that can take up to six hours. An optimized computer program is now able to do this in only a few seconds.
01/10/2018Thanks to various imaging supplies, it is possible to make the inside of the body accessible for diagnostics, research and treatment. The lung, one of the most important human organs for survival, is also examined in this way. In our Topic of the Month, we looked at how doctors are getting a closer look at the lung, how the procedures differ, and which ones will be available in the near future.
01/10/2018Lung cancer is one of the most common and deadliest cancers. The symptoms tend to be non-specific, often causing its detection to be too late. Currently, there is no comprehensive screening. This could change with the use of low-dose CT scans. It should be noted that this is not just an issue of technical feasibility. A screening test must also make sense from a health policy perspective.
03/09/2018In a Smart Hospital, all devices are designed to be connected and integrated, thus increasing efficiency and reducing time loss – at least, that is how things are meant to work in theory. In reality, there are still countless vendor-specific point solutions that cannot be integrated. That's why there is a need for solutions that bridge the gap between the different applications and formats.
04/01/2018Imaging, navigation, integration – these are terms that describe the modern operating room. All of these components play a key role in accurate surgical procedures. They are integrated into surgical navigation systems, which make complicated medical surgeries considerably safer.
