A team of international scientists developed a new non-invasive MRI-based early warning system that may alert physicians about approaching heart attacks in patients and identify those at high risk.

Optical coherence tomography (OCT) offers superior detection of coronary vascular changes compared to angiography in pediatric heart transplant recipients. The technique can be used to improve the medical management in this population.

Quantifying myocardial blood flow (MBF) with CT perfusion (CTP) imaging can accurately predict major adverse cardiac events (MACEs). It also showed improved risk stratification in stenosis patients when paired with coronary CT angiography (CTA), according to a recent JACC: Cardiovascular Imaging study.

The Transportation Security Administration (TSA) has recently started using new Analogic 3D CT machines in a handful of U.S. airports to scan carry-on bags and spot explosives, according to a report published July 23 by CBS.

The National Institutes of Health (NIH)'s Clinical Center made a dataset of more than 32,000 annotated lesions identified on CT images representing 4,400 patients available to the public, according to a July 20 release.

In a series of photographs published July 17 in the New York Times, entitled "Darkness at Noon: My Time in Radiation," a 63-year-old photojournalist illustrates his radiation treatment for a rare type of cancer with personal, raw images—all taken with his iPhone.

Quantitative flow ratio (QFR) outperformed coronary angiography in calculating fractional flow reserve (FFR), a measurement key to determining heart blockages, according to a study in the Journal of the American Heart Association.

EchoNous, the Seattle-based medical tool provider, recently received FDA clearance for the its ultrasound-based tool designed for nurses to improve peripheral IV (PIV) catheter placements.

Myocardial delayed enhancement (MDE) CT rivaled late gadolinium enhanced (LGE) MRI in the detection and classification of myocardial scar in patients with heart failure, according to a recent Radiology study. The results may help identify features of chronic heart failure.

Patients with retrievable inferior vena cava (IVC) filters used to prevent venous thromboembolisms face increased complication risks the longer their device remains in the body. Researchers created an informatics tool to address the issue.

Jointly funded by the federal and Western Australia (WA) governments, a $21 million state-of-the-art MRI suite for patients seeking neurosurgery recently opened in Perth, Australia, according to a July 6 article in The Australian.

Patients with stable coronary artery disease (CAD) monitored with either cardiac MR (CMR) or angiography demonstrated no difference in impact rates over three years, according to a recent JACC: Cardiovascular Imaging study.
