Possible biological explanation for increased cancer risk in dense breasts


The risk of developing breast cancer is higher in what are known as dense breasts, which appear white in mammograms, than in nondense breasts, which appear grey. Researchers at Linköping University, Sweden, have now shown that there are major biological differences dense breasts and nondense breasts.

Breast cancer: ToSyMa study shows superior diagnostic performance of tomosynthesis


Tomosynthesis – the method being extensively tested for early breast cancer detection by ToSyMa, the world's largest randomized controlled trial - appears to be convincing across the entire line.

Radiation against cardiac arrhythmias


At the Hannover Medical School (MHH), radiation is now being used to help patients with cardiac arrhythmias. High-precision radiation from linear accelerators is used to treat the exact spot in the heart muscle that is responsible for the arrhythmia. The procedure is relatively new and is only carried out in a few clinics in Germany.

A tool based on artificial intelligence can automatically detect pathologies in thorax X-rays


A research team has developed a tool for the automatic detection of pathologies in thorax X-rays based on the experience and expertise of radiology staff that are validated from the automatic analysis of medical reports.

Modelling the use of Beta Radiation in cancer treatment


A new paper pits the gold standard simulation method used to calculate the interaction of the ionizing radiation with matter and estimate the radiation dose delivered to a target organ against an alternative analytic method, the Loevinger formula.

Man vs. machine – the benefits of AI in imaging


Radiology 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.

AI in imaging: how machines manage our Big Data


In 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?

Deep Learning Image Reconstruction – what AI looks like in clinical routine


Artificial 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.

MobiKa – programmed to help


Many illnesses or old age require help with everyday tasks. Unfortunately, family members or caregivers aren’t always available to lend a hand. The MobiKa mobile service robot is designed to offer support, deliver motivation and improve the quality of life of those in need.

Gamification: how penguins help children overcome their MRI fear


It'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.

Cardiac arrhythmia: treatment in the linear accelerator


Cardiac 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.
