In wake of the global shortage of iodinated contrast media, researchers modeled several ways to conserve it. They found that a combination of methods could reduce contrast media use for CT scans by approximately 80% if a moderate reduction in diagnostic accuracy could be tolerated. They say changes must be made to minimize supply chain risk in the future.
As a worldwide shortage of contrast dye for medical imaging continues, a new UC San Francisco research letter in JAMA quantified strategies medical facilities can employ to safely reduce dye use in computed tomography (CT) by up to 83%. CT is the most common use for the dye.
Cardiologists from the Structural and Congenital Heart Center and Cardiac Surgeons at Hackensack Meridian Hackensack University Medical Center/Hackensack Meridian School of Medicine have reported what is believed to be the very first patient with heart failure and a blood clot to undergo a minimally invasive transcatheter aortic valve replacement using CT (computed tomography) fusion imaging, a technique that employs two different imaging modalities.
Computed tomography (CT) is used at a higher rate than ultrasound in children with developmental and cognitive impairments to diagnose appendicitis, even though CT scans increase radiation risk in smaller bodies.
Researchers at the University of Notre Dame are developing a new technique using artificial intelligence (AI) that would improve CT screening to more quickly identify patients with the coronavirus.
NIH has launched an ambitious effort to use artificial intelligence, computation, and medical imaging to enable early disease detection, inform successful treatment strategies, and predict individual disease outcomes of COVID-19.
A new study examines the factors associated with a potentially missed diagnosis of appendicitis in children and adults in the emergency department.
Scientists have developed a computed tomography (CT) scanning method for screening large samples of wheat for drought and heat tolerance. They believe the new system will allow more accurate and much more rapid analysis of wheat heads, speeding up the process of breeding for plants better adapted to climate change
Experts believe that tuberculosis, or TB, has been a scourge for humans for some 15,000 years, with the first medical documentation of the disease coming out of India around 1000 B.C.E. Today, the World Health Organization reports that TB is still the leading cause of death worldwide from a single infectious agent, responsible for some 1.5 million fatalities annually. Primary treatment for TB for the past 50 years has remained unchanged and still requires patients to take multiple drugs daily for at least six months. Successful treatment with these anti-TB drugs — taken orally or injected into the bloodstream — depends on the medications “finding their way” into pockets of TB bacteria buried deep within the lungs.
