26/11/2021Obtaining an accurate speed of sound (SoS) inside the body leads to improved resolution of ultrasound or photoacoustic (PA) images. However, it is difficult to accurately predict the SoS since it differs from person to person, depending on the random distribution of muscle, bone, and fat in each individual.
25/11/2021In order to detect and research diseases, it is important to look inside the body. For this purpose, there are various imaging methods – from ultrasound examinations to X-rays and computer tomography. Molecular imaging provides a particularly precise insight, showing biological processes and organ functions "live".
19/11/2021According to an open-access Editor's Choice article in ARRS' American Journal of Roentgenology (AJR), convolutional neural networks (CNN) trained to identify abnormalities on upper extremity radiographs are susceptible to a ubiquitous confounding image feature that could limit their clinical utility: radiograph labels.

10/11/2021Transcranial focused ultrasound can be used to treat degenerative movement disorders, intractable pain, and mental disorders by delivering ultrasound energy to a specific area of the brain without opening the skull. This treatment must be performed with an image-based technology that can locate the brain lesions. Doctors typically use CT to obtain information about a patient's skull.
29/10/2021Immunotherapy using checkpoint inhibitors can work well to treat cancer, but only a minority of patients respond to therapy. Researchers at the University of Alabama at Birmingham have now shown — in preclinical experiments — how to identify non-responding tumors and improve their response to immunotherapy, as shown by limited tumor growth and extended survival.
27/10/2021Strokes are the cause of various disabilities, as they damage the brain such that some areas do not function properly any more. Those areas are called lesions. Directly identifying or predicting lesions in clinical daily routine is still not possible with today's imaging tools, creating the need for new software solutions.
27/10/2021For the first time, researchers at the Technical University of Munich (TUM) have successfully used a new X-ray method for respiratory diagnostics with patients. Dark-field X-rays visualize early changes in the alveolar structure caused by the lung disease COPD and require only one fiftieth of the radiation dose typically applied in X-ray computed tomography.
22/10/2021Scientists from Skoltech, Philips Research, and Goethe University Frankfurt have trained a neural network to detect anomalies in medical images to assist physicians in sifting through countless scans in search of pathologies. Reported in IEEE Access, the new method is adapted to the nature of medical imaging and is more successful in spotting abnormalities than general-purpose solutions.
20/10/2021It remains a central challenge in psychiatry to reliably judge whether a patient will respond to treatment. In a new study researchers show that moment-to-moment fluctuations in brain activity can reliably predict whether patients with social anxiety disorder will be receptive to cognitive behavioral therapy (CBT).
18/10/2021Humans are stepping ever closer to understanding how the brain codes visual information, as researchers have now developed a method that maps time-varying brain responses to images to reveal how the brain processes visual information.
13/10/2021Type 2 diabetes can be diagnosed with a whole-body magnetic resonance imaging (MRI) scan. This is shown by a current study. They used deep learning methods* and data from more than 2000 MRIs to identify patients with (pre-) diabetes. The results have now been published in the journal JCI Insight.
11/10/2021Neuroscientists discovered a novel, non-invasive imaging-based method to investigate the visual sensory thalamus, an important structure of the human brain and point of origin of visual difficulties in diseases such as dyslexia and glaucoma. The new method could provide an in-depth understanding of visual sensory processing in both health and disease in the near future.
01/10/2021Scientists utilised SNAP-tag technology to radioactively label cells in living organisms. They developed a SNAP-tag substrate equipped with a radioactive signal emitter and used it to make tumour cells in the bodies of mice visible in PET images. The labelling method opens up the prospect of studying cells with different imaging techniques and at different temporal stages.
29/09/2021The University of Texas M. D. Anderson Cancer Center and Siemens Healthineers announced the collaborative development of a global education program focused on enabling the implementation of consistent, high-quality magnetic resonance (MR) imaging in radiationoncology. They are also collaborating to develop standardized MR protocols that will improve quantitative response assessment.
01/04/2021For surgeons, nothing is more important than intimate knowledge and a spatial understanding of their operating field. Yet even three-dimensional imaging methods only provide limited assistance because the data is viewed on two-dimensional screens. When it comes to surgical planning or medical education, Mixed and Virtual Reality foster a better spatial understanding of the human body.
01/04/2021The job of surgeons starts long before they step into the operating room. They must use two-dimensional MRI or CT scans to plan the surgical steps on a three-dimensional patient, relying on their experience, skill, and spatial sense. Using mixed reality (MR) to view human anatomical models allows for better visualization and navigation.
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.
01/04/2019A surgery already begins before the patient is lying on the operating table – namely with the planning. For example, if brain surgery is imminent, the brain must first be mapped. This makes the activity level of certain brain areas visible. Functional magnetic resonance imaging makes this possible.
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.
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?
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.
01/10/2018Thanks 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.
08/08/2018Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.
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.
