The researchers have found that blue light can be used to probe the depths of the eye and uncover areas affected by DR.
An AI-led device to assess coronary CT angiographs has been designed to assess cardiac plaque that may lead to myocardial infarction (MI). In his presentation ‘Vascular inflammation and cardiovascular risk assessment using coronary CT angiography’ (CCTA), Charambalos Antoniades, Professor of Cardiovascular Medicine at the University of Oxford, presented the research team’s findings during…
Artificial intelligence (AI) could match the impact of PACS on radiology. Covid-19 stimulated the development and testing of AI diagnostic-aiding tools in radiology, an unintended consequence of the pandemic. More image data sets have been created to train AI software – an unexpected benefit for radiology research.
For the first time, a prospective, international study has shown that chest pain caused by problems with the very small vessels supplying blood to the heart is an important health problem that increases the risk of heart attacks, stroke and death due to cardiovascular reasons. The study, which is published in the European Heart Journal, recruited 686 patients from 14 institutions in seven…
Acute stroke in children has the same incidence as brain tumours and can seriously affect a patient’s life. Two kinds of arteriopathies are common drivers of paediatric acute stroke and radiologists must learn to distinguish their signs as early as possible to improve prognosis, according to Béatrice Husson, a paediatric radiologist at Le Kremlin Bicêtre Hospital in Paris.
Sending a “selfie” to the doctor could be a cheap and simple way of detecting heart disease, according to the authors of a new study. The study is the first to show that it’s possible to use a deep learning computer algorithm to detect coronary artery disease (CAD) by analysing four photographs of a person’s face. Although the algorithm needs to be developed further and tested in larger…
As radiologists worldwide continue to share their knowledge of COVID-19 to help fight the pandemic, two chest experts from France and Spain talked about their country perspectives and the practical experience at their hospital in a dedicated online session organized by the European Society of Radiology (ESR).
Technology developed using artificial intelligence (AI) could identify people at high risk of a fatal heart attack at least five years before it strikes, according to new research funded by the British Heart Foundation (BHF). The findings are being presented at the European Society of Cardiology (ESC) Congress in Paris and published in the European Heart Journal. Researchers at the University of…
Doctors could soon get some help from an artificial intelligence tool when diagnosing brain aneurysms—bulges in blood vessels in the brain that can leak or burst open, potentially leading to stroke, brain damage or death.
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…
While the question is still debated as to whether MRI is the better CT, along comes a potential game changer – a new data based 3-D reconstruction method of heart anatomy and function that aims to replace diagnostic coronary angiography. In the near future not only adult patients with coronary heart disease could benefit from this new technique but also children with complex congenital heart…
A new software to calculate the pressure drop and vFFR value (vessel Fractional Flow Reserve) in the coronary artery non-invasively was presented to interventional cardiovascular experts at EuroPCR 2018 in Paris. The software called CAAS vFFR (Cardiovascular Angiographic Analysis Systems for vessel Fractional Flow Reserve) was developed by Pie Medical Imaging (Esaote Group). The vFFR calculation…
Population imaging is key to determining disease prediction and risk prevention, and Big Data will be key to extracting information and drawing analysis from imaging results, experts highlighted during the annual meeting of the European Society of Magnetic Resonance in Medicine and Biology (ESMRMB) held in Barcelona in October. Interest in cohort studies has been increasing over the years and…
Coronary angioplasty is arguably the most revolutionary breakthrough in the history of cardiology. While the technique is today performed on millions of patients worldwide, its origins can be traced back to Zurich, Switzerland, in the late 1970s.
It is a collaboration that could push vascular imaging to a new level.
Stroke patients will first undergo a CT scan as they enter the hospital. Before any further imaging scan is carried out, the medical team must decide whether they need to intervene intra or extra cranially. ‘Imaging enables you to see which pathology you are dealing with and helps you select patients for either recanalisation or revascularisation or, in some cases, occlusion by embolisation,’…
Joshua Bederson, MD, Professor and System Chair for the Department of Neurosurgery at Mount Sinai Health System, is the first neurosurgeon to use CaptiView – a microscope image injection system from Leica Microsystems that overlays critical virtual reality imaging directly onto the brain when viewed through the eyepiece, known as the ocular, during surgery.
Researchers have identified a new test that can be used to predict the likelihood of a patient developing heart failure, or even dying following a heart attack.
Many NHS hospitals in the United Kingdom have established Rapid Access Chest Pain Clinics (RACPC) to work in tandem with them in offering primary percutaneous coronary intervention (PPCI) – the gold standard treatment for heart attacks – 24 hours a day. Report: Mark Nicholls
The heart is a structure in three dimensions and today we see it in three dimensions,’ Jose Luis Zamorano Gomez MD declared with satisfaction.
Computed tomography (CT) has become central to the diagnosis and characterisation of coronary artery disease (CAD) and, in the future, could even supplant invasive coronary angiography as the technology increases sensitivity.
Because of improved management at the acute stage, the risk of dying in hospital after a heart attack has decreased by about 50% in the past 10 years. Likewise, the prescription of recommended medications when patients leave hospital, has resulted in improved survival and fewer recurrent heart attacks.
In the historical city of Gouda, in the Netherlands, the 441-bed Groene Hart Ziekenhuis (Green Heart Medical Centre) employs about 150 doctors and serves a local population of 450,000 people. Last September it became the first hospital in Europe to install the new Carestream Cardiology PACS. Launched in 2009, the PACS provides a single integrated platform for diagnosis, reporting, storage and…
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).
There's no reason to forgo a needed radiation-based medical procedure because of concerns about cancer risk, according to the October issue of Mayo Clinic Health Letter. While the volume of radiation-based tests and procedures has increased in the past three decades, scientists haven't proven that the low doses of radiation used in medical settings actually increase cancer risk.
