A new diffusion tensor imaging technique can help predict problems related to dementia in patients with stroke-related small vessel disease, according to research published in Stroke.

“We anticipate that these expert multisocietal consensus recommendations on multimodality imaging in cardiac amyloidosis will standardize the diagnosis and improve the management of this highly morbid and underdiagnosed disease," wrote authors of the new guidelines published in the Journal of Nuclear Cardiology.

Researchers from the University of Oxford have created a new biomarker based off of coronary CT angiography (CCTA) images that can select patients at a high risk of heart attack five years before they occur.

A new three-dimensional (3D) MRI technique can measure strain in the heart without using potentially-damaging gadolinium, according to new research out of the University of Warwick in the U.K.

Greater left ventricular mass identified on MRI is a better predictor of coronary artery disease-related death and heart failure compared to coronary artery calcium (CAC) scoring, reported authors of a multi-center study published in Radiology.

"These products are advertised as not harmful, and many e-cigarette users are convinced that they are just inhaling water vapor," said researchers in a recent article published by Radiology.

Resting echocardiography stands head above shoulders as the most used imaging modality for patients with heart failure in Canada, according to a 14-year analysis published in JAMA Network Open.

“Knowledge of CAC on a prior chest CT may eliminate the need for a subsequent dedicated gated calcium score CT, leading to earlier diagnosis and management of cardiovascular disease as well as decreasing radiation exposure and health care costs,” wrote authors of a July 26 study.

“Our multicenter study found that 4D flow MRI provided a promising way of measuring blood flow in the superior and inferior caval veins and right heart, which may provide further insight into physiologic and pathologic blood flow patterns in individuals with COPD and emphysema,” wrote researchers in a July 24 Radiology study.

A high coronary artery calcium (CAC) score was linked to an increased risk for cardiovascular disease (CVD) and mortality in patients between 30 and 49 years old, researchers of a new study published in JAMA Network Open found.

Medtronic and Viz.ai, a growing leader in artificial intelligence, are collaborating on a new software to automatically alert specialists when a stroke is identified during a CT scan.

The FDA has approved Bayer’s gadobutrol (Gadavist) injection for use in cardiac MRI, making it the first contrast agent approved for the imaging technique, according to a statement from Bayer.
