More and more people aged 50 and over are suffering from age-related vision disorders. According to the World Health Organization, in four out of five cases they could be avoided if they were diagnosed at an early stage. A European team of scientists, including the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, has now researched a new method that will enable doctors to better…
Interventional cardiologists have been aware of the value of intracoronary (IC) imaging in clinical practice for more than twenty years. However, recent developments and improvements in modalities and software have enabled huge strides in its range and scope for both diagnostic assessment and in percutaneous coronary interventions. Imaging options now include intravascular ultrasound (IVUS),…
Pathologic-radiologic correlation is already utilised in various settings as a tool to assess the interpretive performance of imaging studies and identify radiologic features corresponding to histologic findings. However, correlative assessment is currently limited mainly to the fields of research and quality assurance, and is generally not a routine element of the radiologist or pathologist…
Siemens Healthineers and Mentice AB announced the collaboration to fully integrate Mentice’s VIST Virtual Patient into the Artis icono angiography system from Siemens Healthineers. The VIST Virtual Patient thus becomes a fully integrated simulation solution for the angio-suite. The global partnership between the two companies will allow interventional radiologists, neuroradiologists, and…
A researcher has created an objective model that classifies the degrees of the iridocorneal angle, a key element for assessing the severity of glaucoma. With this model, ophthalmologists will have a tool to help patients make a decision when considering surgery.
Doctors aren’t sure what causes age-related macular degeneration, a disease that affects millions of people in the United States. Also called AMD, it is known for causing blurred central vision due to damage to the macula — a small area at the back of the eye. Currently, there is no cure. But there are known risk factors that eye care professionals often use to help determine a patient’s…
A wearable brain-based device called NGoggle that incorporates virtual reality (VR) could help improve glaucoma diagnosis and prevent vision loss. Duke University researchers funded by the National Eye Institute (NEI) have launched a clinical study testing the device in hopes that it could decrease the burden of glaucoma, a major cause of blindness in the U.S. The device consists of head-mounted…
MRI has a central role in picking up myocardial infarction with non-obstructive coronary disease, a condition that particularly affects women but is often left untreated, with potentially fatal outcome. Heart attack in women presents differently than in men and requires a different approach when it comes to detection and prevention, according to cardiologist Allison Hays.
AI-based applications will replace radiologists in some areas, the physicist Bram van Ginneken predicts. ‘The profession of radiologist will change profoundly,’ predicts Gram van Ginneken, Professor of Medical Image Analysis at Radboud University Medical Centre. The cause is automatic image analysis by computers (first published in a paper in 1963) and deep learning.
Although dementia is most often seen in adults, childhood or adolescent dementia does occur. A team of researchers from the University of Würzburg believes that established therapeutic drugs might be effective against childhood dementia.
Scientists have many tools at their disposal for looking at preserved tissue under a microscope in incredible detail, or peering into the living body at lower resolution. What they haven't had is a way to do both: create a three-dimensional real-time image of individual cells or even molecules in a living animal.
Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible while keeping crucial brain tissue intact — and visually distinguishing the two is often impossible. Now Johns Hopkins researchers report they have developed an imaging technology that could provide surgeons with a…
Research published in the Proceedings of the National Academy of Sciences (PNAS) demonstrates that technology invented by researchers at Oregon Health & Science University’s Casey Eye Institute can improve the clinical management of the leading causes of blindness. Optical coherence tomography (OCT) angiography could largely replace current dye-based angiography in the management of these…
Nowadays the concept of personalised medicine is usually applied to oncology. However, there are other clinical disciplines in which therapies tailored to the individual patient are within reach, viz. ophthalmology. In the researchers’ limelight is intravitreal drug delivery since the outcomes of injections into the vitreous differ from patient to patient. Ophthalmologists in Vienna, Austria,…
Among new medical imaging innovations is a phase-contrast x-ray technique to bring greater precision to breast cancer assessment and improve biopsy diagnostics. EH asked research pioneer Professor Marco Stampanoni, a key figure in the development of this technique, to explain how it works. Report: Sascha Keutel
New imaging technologies are opening a new chapter in interventional cardiology by offering something this widely practiced procedure has been missing -- vivid clinical evidence to assess effectiveness. Interventional cardiology has moved rapidly from opening blocked arteries by crushing plaque with inflatable balloons to reinforcing the walls of the re-opened arteries with flexible metal stents…
The landmark achievements in interventional cardiology that are rapidly advancing minimally invasive surgeries (MIS) on a beating heart were demonstrated during a Paris course on revascularisation (EuroPCR), the annual meeting of the European Association of Percutaneous Cardiovascular Interventions (EAPCI).
A probe suitable for imaging soft tissue for use with the VivoSight Multi-Beam optical coherence tomography (OCT) imaging system has been launched by manufacturer Michelson Diagnostics. The probe enables in vivo imaging of oral and gynaecological tissue.
Molecular imaging, the discipline that unites molecular biology and in vivo imaging technologies to assess biological activity in the body, promises to open up ‘…an entire new universe,’ declared Dr Ralph Weissleder, of the Centre for Molecular Imaging Research at Massachusetts General Hospital, USA, in the journal Radiology.
