Dementia – MRI is the first step in diagnosis

Brain imaging in patients with cognitive complaints need to be viewed differently when using MRI to diagnose and treat patients with dementia, says Dr. Christopher Hess, who will discuss the role of MRI in the adjunctive diagnosis of dementia in his talk at the Garmisch Symposium. In addition, general radiologists need to recognize the important findings related to dementia when making a…

New device for screening arterial stiffness and diagnosing CVD

Researchers have developed a prototype medical device based on silicon photonics for the screening of arterial stiffness and for the diagnosis of cardiovascular diseases such as arterial stenosis and heart failure. This is a cooperation between imec, the world-leading research and innovation hub in nanoelectronics and digital technology and Ghent University, together with Medtronic and other…

Promising diagnostic tool

Tracing tau tangles against Alzheimer’s

Researchers at Johns Hopkins Medicine have identified in live human brains new radioactive “tracer” molecules that bind to and “light up” tau tangles, a protein associated with a number of neurodegenerative diseases including Alzheimer’s disease and other related dementias. Two studies will be published back-to-back in the December issue of Journal of Nuclear Medicine—one as featured…

Vaginitis - Diagnosis of Sexually Transmitted Gynecological Infections

Vaginitis is one of the most common problems in clinical medicine, and it is the reason cited most often for visits to obstetricians and gynecologists. In a special webinar, Prof. Dr. Werner Mendling will discuss the 2018 European International Union against Sexually Transmitted Infections (IUSTI) and World Health Organisation (WHO) guidelines on the management of vaginal discharge in detail. …

Evolving technique

Flow cytometry rises to new challenges

Flow cytometry has proved an invaluable diagnostic tool for leukaemia and lymphoma for almost three decades. Now, however, this is evolving in applications to seek out residual disease in cases and in fusion with molecular testing to advance its diagnostic potential. However, although recognised as fast, flexible and accurate, flow cytometry suffers from a lack of standardisation, according to…

Going digital

Faster and better diagnosis of cancer with digital pathology

Leeds Teaching Hospitals NHS Trust and the University of Leeds have announced a critical milestone in going digital, by scanning every glass slide they produce. The milestone represents a major step towards achieving faster and accurate diagnosis for cancer patients in the future. The Pathology Department, located in St. James’ Hospital in Leeds, is one of the largest in the UK processing over…

AI ethics and responsibilities

A journey into human/machine interactions in healthcare

With Artificial Intelligence (AI) able to deliver diagnostic advances for clinicians and patients, the focus has shifted towards ensuring the technology is used in an ethical and responsible way. As evidence emerges of a gap in research on ethical deployment of AI, Dr Gopal Ramchurn is embarking on a three-year research project that will look at setting parameters for AI usage, with a key aspect…

Digital Photon Counting improves diagnostic accuracy

Built as the first commercially available scanner to deliver truly digital PET, the Vereos PET/CT, from Philips, offers revolutionary Digital Photon Counting technology. The science behind this scanner evolution is ‘quite complicated’, agrees Piotr Maniawski, Director of Clinical Science Nuclear Medicine at Philips Healthcare, yet the improved performance is significant, particularly when…

'Radiologists who do not use AI will be replaced by those who do'

Recent developments in artificial intelligence (AI) created a veritable hype. However, that initial awe was increasingly mixed with apprehension about the potential effects of AI on healthcare. In radiology, bleak dystopias are conjured up with AI replacing the human radiologist. A scenario that Dr Felix Nensa, consultant at the Institute of Diagnostic and Interventional Radiology and…

Ultrasound aids ear infection diagnosis

Although traditionally an imaging modality, ultrasound also has applications as a measurement tool. An innovative application is to assess ear infections. Otitis Media (OM), a middle ear infection, is the number one indication for antibiotic prescriptions for children and the leading cause for surgery. This problem is global. Nearly every child will suffer at least one middle ear infection severe…

AI system improves heart disease diagnosis

Cardiologists in the UK are trialling an artificial intelligence (AI) system that will help better diagnose heart disease. Devised by researchers from the University of Oxford, it can predict heart disease and cardiac events from ultrasound stress test images with initial results showing that the AI system is far more accurate than conventional techniques. Paul Leeson, Professor of Cardiovascular…

Digitisation and automation: Game-changers in histopathology?

Often referred to as the ‘Achilles’ heel’ of histopathology, the sample entry has posed considerable challenges in pre-analytics for several decades. We visited the Munich-based lab automation start-up Inveox GmbH. Time-intense, highly manual processes in labs are expensive, error-prone and the most common reason for irregularities in cancer diagnoses. In Germany alone, every year hundreds…

'Smart' surfaces might pave the way for safer implants and better diagnostics

Researchers at McMaster University have solved a vexing problem by engineering surface coatings that can repel everything, such as bacteria, viruses and living cells, but can be modified to permit beneficial exceptions. The discovery holds significant promise for medical and other applications, making it possible for implants such as vascular grafts, replacement heart valves and artificial joints…

The future POCT heart attack test

Experts report that a new blood test to diagnose heart attacks could be carried out on a hand-held device in the not-too-distant future. The test, devised by a team at Kings College London, uses similar technology to the troponin test, but instead analyses cardiac myosin-binding protein C (cMyC). In research presented at the British Cardiovascular Society conference in Manchester, UK, this June,…

Potential diagnostic test for Kawasaki disease

For the first time, researchers at University of California San Diego School of Medicine and Imperial College London, with international collaborators, have determined that Kawasaki disease (KD) can be accurately diagnosed on the basis of the pattern of host gene expression in whole blood. The finding could lead to a diagnostic blood test to distinguish KD from other infectious and inflammatory…

When the phosphate decides...

Defense against viruses or autoimmune disorder?

The first defense line of the body against virus infections is composed of so-called restriction factors. SAMHD1, one of such restriction factors, does not only play a role in the defense against viruses but also in the development of autoimmune disorders and cancer. The question of which effect SAMHD1 exertsin the cell is decided by addition or removal of phosphate groups.
