23/04/2019It's noisy, tight and scary - that's how children feel about a magnetic resonance imaging (MRI) machine. Because they are scared, they are often too fidgety and anxious during the procedure, causing the images to blur or the scan to be stopped. Researchers have now developed a VR app called Pingunauten Trainer that’s designed to gently prepare the little patients for MRI scans.
22/04/2019In August 2018, a workshop was held at the National Institutes of Health (NIH) in Bethesda, Md., to explore the future of artificial intelligence (AI) in medical imaging. The workshop was co-sponsored by NIH, the Radiological Society of North America (RSNA), the American College of Radiology (ACR) and The Academy for Radiology and Biomedical Imaging Research (The Academy).
18/04/2019UCLA researchers have developed a new artificial intelligence system to help radiologists improve their ability to diagnose prostate cancer. The
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.
03/04/2019A team from Heidelberg University Hospital and the German Cancer Research Centre has developed a new method for the automated image analysis of brain tumors. In their recent publication, the authors show that machine learning methods carefully trained on standard magnetic resonance imaging (MRI) are more reliable and precise than established radiological methods in the treatment of brain tumors.
02/04/2019An essential part of breast intervention is the process of assessing concordance between imaging findings and core biopsy results. When pathology results are considered benign discordant, current standard of care is surgical excision, even though many of these lesions will ultimately be found benign.
02/04/2019A prototype wearable device, tested in animal models, can continuously collect live cancer cells directly from a patient's blood. The device developed by a team of engineers and doctors at the University of Michigan could help doctors diagnose and treat cancer more effectively.
26/03/2019Immersive virtual reality (VR) may enable interventional radiologists to improve treatments using real-time 3D images from inside a patient's blood vessels. New research shows that the interactive technology could provide faster, more efficient treatment, with less radiation exposure and greater precision, ease and confidence.
18/03/2019A new method to diagnose cancer cells inside lymph nodes could allow doctors to treat cancers before they spread around the body
15/03/2019The debilitating side effects of radiotherapy could soon be a thing of the past thanks to a breakthrough by University of South Australia (UniSA) and Harvard University researchers. UniSA biomedical engineer Professor Benjamin Thierry is leading an international study using organ-on-a-chip technology to develop 3D models to test the effects of different levels and types of radiation.
25/02/2019In an effort to further individualize breast cancer therapy and avoid over-treating patients, researchers at the Johns Hopkins Kimmel Cancer Center report a new study using PET scans has identified a biomarker that may accurately predict which patients with one type of HER2-positive breast cancer might best benefit from standalone HER2-targeted agents, without the need for standard chemotherapy.
20/02/2019A first-in-human study featured in The Journal of Nuclear Medicine reports that the novel positron emission tomography/computed tomography (PET/CT) tracer 18F-GP1 showed excellent image quality and a high detection rate for the diagnosis of acute venous thromboembolism (VTE).
01/02/2019Dr. Paul Harch, Clinical Professor and Director of Hyperbaric Medicine at LSU Health New Orleans School of Medicine, and Dr. Edward Fogarty, Chairman of Radiology at the University of North Dakota School of Medicine, report the first PET scan-documented case of improvement in brain metabolism in Alzheimer's disease in a patient treated with hyperbaric oxygen therapy (HBOT).
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.
01/10/2018Lung 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.
01/08/2018For years, medicine has been exploring AI techniques aimed at easing physician workload. While computers may not have the medical expertise and skills obtained through years of study, they can recognize patterns and specific features in datasets and draw deductions.
08/03/2018Automation makes work life easier in many ways but is it also a solution for analyzing medical images? Is a computer actually reliable enough to assist in the medical decision making process? Researchers in Landshut examine how machine learning algorithms can work more reliably and support radiologists.
10/07/2017Radiation therapies are an essential component of today’s oncology because they enable the treatment of localized tumors. Yet they have one major drawback: radiation damages not just tumor cells but also healthy tissue. One solution to solve this problem could be proton minibeam therapy, which uses finely focused beams.
13/04/2017These days, medical imaging is one of the key diagnostic methods. But how do large medical devices actually get to their final destination? MEDICA-tradefair.com took its camera along to observe the remodeling of a radiology imaging office. The leading actors: a CT scanner and an MRI machine.
08/03/2017Pneumonia is the most frequent respiratory disease in children and can even cause death. That is why it is extremely important to make an accurate diagnosis as quickly as possible. If this requires imaging tests, normally X-rays are taken. But there is an alternative: ultrasound.
