Coronary artery calcium (CAC) scoring could be the key to determining which patients are most likely to benefit from statin therapy, according to a retrospective analysis published Nov. 5 in the Journal of the American College of Cardiology.

Automated cardiac valve tracking halved the analysis time and variability in blood-flow quantification with four-dimensional (4D) flow MRI, researchers reported in Radiology. The algorithm may help clinicians more efficiently assess the severity of congenital and valvular heart disease, they said.

Researchers from the Netherlands demonstrated, in a study published Oct. 30 in Radiology, that four-dimensional (4D) flow MRI with automated cardiac valve tracking reduces analysis time and improves reliability of valvular flow quantification compared to manual valve tracking in patients with congenital heart disease.

An augmented reality (AR) technique involving 3D visualization of myocardial scar can assist physicians in evaluating and treating cardiac damage during electrophysiological interventions like ventricular tachycardia (VT) ablation, researchers reported in PLOS One.

About 96 percent of women want to be notified about breast arterial calcification (BAC) detected during mammography, according to survey results published in the American Journal of Roentgenology. Researchers said breast radiologists are in a strong position to connect these patients to preventive cardiologists.

A patent filed in 2014 by Apple Inc. for a new method to print three-dimensional (3D) models using triangular tessellation was recently approved by the U.S. Patent and Trademark Office on Tuesday, Oct. 23, according to a report by TechCrunch.com.
