Doctors who give advanced breast cancer patients just one estimate, such as 12 months, for the average amount of time they are expected to live are only accurate 20-30% of the time, according to Dr Belinda Kiely, medical oncologist and senior research fellow at the University of Sydney, Australia.
Researchers at National Jewish Health and dozens of leading institutions around the nation have proposed new criteria for diagnosing chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in the United States. The proposal expands diagnostic criteria from a single measure of lung function to include environmental exposure, symptoms, and abnormal CT scans.
Biopsies are standard procedures in interventional radiology, not least for patients with a suspected tumor. In this instance, MRI is increasingly the method of choice for guiding minimally invasive tissue sampling. Yet this involves having to undergo repeated MRI scans, which patients find uncomfortable. In an ongoing R&D project, Fraunhofer researchers have now developed a system that…
Artificial Intelligence (AI) is like a huge blanket that can cover anything from innocuous chess computers to robots which, depending on your viewpoint, could save, oppress or obliterate humanity. However, not every jar labelled AI contains AI. So what is intelligence and can it be created artificially, synthesised like a nature-identical flavouring substance?
Researchers have developed a neural network approach that can accurately identify congestive heart failure with 100% accuracy through analysis of just one raw electrocardiogram (ECG) heartbeat, a new study reports. Congestive heart failure (CHF) is a chronic progressive condition that affects the pumping power of the heart muscles. Associated with high prevalence, significant mortality rates and…
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…
Analytically sensitive and specific detection of pharmaceuticals or metabolites in bodily fluids, as well as fast and reliable detection of human pathogens, are major challenges for instrument-based analytics in medical diagnostics. Over the past few years the combination of surface-enhanced Raman spectroscopy (SERS) and microfluidic devices (Lab-on-a-Chip) has emerged as a perfectly suited…
The World Health Organisation's (WHO) Essential Medicines List and List of Essential Diagnostics are core guidance documents that help countries prioritize critical health products that should be widely available and affordable throughout health systems. Now, updated versions of the two lists have been published, focusing on cancer and other global health challenges, with an emphasis on effective…
A new study has concluded that psychiatric diagnoses are scientifically worthless as tools to identify discrete mental health disorders. The study, published in Psychiatry Research and led by researchers from the University of Liverpool, involved a detailed analysis of five key chapters of the latest edition of the widely used Diagnostic and Statistical Manual (DSM), on ‘schizophrenia’,…
Treating physicians need information about the molecular subtype of the tumor if they are to provide targeted therapy for colorectal carcinoma. A research team from University Hospital Zurich and the University of Oxford have now developed a method to predict the molecular classification of colorectal cancer from digital pathology slides.
MRI is a complicated imaging modality and improving it requires a deep understanding of the physics involved. Scientists at Boston University have been working on improving MRI’s signal-to-noise ratio using special metamaterials that are made of arrays of helical resonators.
A recent study can help governments understand which diagnostic laboratory tests are most important when developing universal health coverage systems. Researchers from five countries found that diagnostic laboratory tests are used similarly around the world, even though the institutions they studied differed in terms of poverty levels, health systems and prevalence of disease. “Even though…
A quick and easy test to detect cancer from blood or biopsy tissue could eventually result in a new approach to patient diagnosis. The test has been developed by University of Queensland researchers Dr Abu Sina, Dr Laura Carrascosa and Professor Matt Trau, who have discovered a unique DNA nanostructure that appears to be common to all cancers. Cancer is an extremely complicated and variable…
As mass spectrometry proves to be a more consistent and accurate tool in biochemical measures, with acknowledged advantages over immunoassays, its role in diagnostics has escalated. Headed by Professor Ruth Andrew, the pioneering Mass Spectrometry Core Facility at the University of Edinburgh, aims to offer researchers access to expert scientists and specialist resources to support clinical…
Beckman Coulter is launching the ClearLLab 10C System for the clinical flow cytometry lab. The new system is the first 10-color IVD panel of immunophenotyping reagents cleared by the Food and Drug Administration (FDA) for both lymphoid and myeloid lineages. The four dry pre-mixed antibody tubes use the company’s DURA Innovations technology, eliminating the need to pipette antibodies, improving…
T2 Biosystems, maker of rapid diagnostic technology to aid in the detection of blood stream infections to prevent sepsis, will host an integrated symposium titled “Rapid Diagnostics Direct from Whole Blood: A Solution for Fast and Appropriate Antimicrobial Therapy,” at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Amsterdam, Monday, April 15, 16:00-18:00…
Hackers can access a patient's 3-D medical scans to add or remove images of malignant tumors, thus placing patients at risk of misdiagnoses. The new study, published by Ben-Gurion University of the Negev cybersecurity researchers, showed that the altered scans successfully deceived both radiologists and artificial intelligence algorithms used to aid diagnosis. A 3-D CT (computerized…
Researchers from the University of Bath are developing a new tool for detecting the presence of Dengue fever early on, helping prevent people from suffering potential life-threatening complications.
The blood test used to diagnose a heart attack (acute myocardial infarction) in patients admitted to hospital can be misleading, warn researchers in a study published by The BMJ.
Scientists put AI systems to the test und provide a glimpse into the diverse “intelligence” spectrum observed in current AI models.
AI algorithms are making their way not just into diagnostic workstations, but will also in future be found in the diagnostic methods themselves. Prof. Mathias Goyen, Chief Medical Officer Europe at GE Healthcare, discusses AI algorithms in radiology. "According to a study by the consultancy firm Accenture, the estimated annual market volume for AI applications in healthcare in the USA will…
Current faecal blood tests for colorectal cancer have a sixty percent false positive rate. New funding from Cancer Research UK is helping scientists at Cardiff University to find better, safer tests. Inaccuracy of initial tests for colorectal cancer are putting patients at unnecessary risk, highlighting vital need for the development of precise and non-invasive testing. A grant of over £400,000…
Horiba Medical announces the availability of a D-Dimer reagent for their semi-automated Hemostasis instruments. The D-Dimer is a key measurement and the reference exclusion test for the diagnosis of deep vein thrombosis or pulmonary embolism and may also be used for monitoring Disseminated Intravascular Coagulation. The new Yumizen D-Dimer reagent kit is available for Yumizen G hemostasis…
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…
