Homeland Security issues advisory for 4 Siemens imaging systems

The Department of Homeland Security (DHS) and Siemens Healthineers issued an advisory that four of the company’s diagnostic imaging systems may be vulnerable to cyberattacks.

MRI capable of aorta ‘action shots’ in exercising patients

Researchers, led by Johan Heiberg, PhD, from Aarhus University Hospital in Denmark, were able to produce high-quality MR images of patients’ hearts using an ergometer bike mounted on an MRI scanner table.

Risk-reward: Knowing when to use coronary CT angiography

Every year, eight million Americans visit emergency departments with acute chest pain. Coronary CT angiography (CCTA) is commonly used to triage patients with acute coronary syndrome (ACS). In a recent article in Journal of the American College of Radiology, a team of researchers looked at when CCTA best served patients with acute chest pain, urging EDs to avoid use on high-risk patients according to JAMA’s Choosing Wisely recommendations.

Cardiologists may be able to see, stop stroke-causing clots with 3D imaging

Researchers have developed a new method of studying blood clots in 3D through optical microscopy. Such understanding of the internal architecture of clots can help cardiologists identify and diagnose clots that may put patients at risk for stroke or heart attack.

Radiologists develop algorithm, contingency plan for MRI in pacemakers patients

By some estimates, at least half of those with cardiovascular implantable electronic devices (CIEDs), who are already experience cardiovascular difficulties, will require MRI during their lifetime. A research team from Changi General Hospital and Singhealth Radiology Singapore have unveiled an algorithm and contingency plan to ensure the safety of CEID patients when undergoing MRI.

Dutch designers use optical fiber for MRI-compatible cardiac catheter

A prototype developed by a Dutch team replaces a cardiac catheter’s wire leads with optical fiber, which provides both power and control. The design shows the potential for physicians to conduct measurements with MRI.

Expanding the Imaging Toolbox to Enhance Women’s Care

Cardiac imaging plays an important role in the cardiac care continuum, and choosing the right test can mean all the difference in quality care for both women and men.  

Experimental ultrasound tool eradicates blood clots

A new tool that uses low-frequency intravascular ultrasound to break down blood clots that cause deep vein thrombosis is being tested by researchers at North Carolina State University and the University of North Carolina at Chapel Hill.

New cardiac imaging FFRct gets high rating from BCBS

HeartFlow, a cardiac technology company in Redwood City, California, has received positive reviews on its HeartFlow FFRct, a non-invasive technology that uses coronary CT angiograms to make personalized 3D models of a patient’s arteries.

Imaging study reveals new ways to widen blood vessels

Pharmacological stress agents given to patients during a cardiac stress test can cause severe side effects, but a new study using PET/MR imaging has revealed that using arterial carbon dioxide (PaCO2) can safely and efficiently widen blood vessels.
