Cardiovascular Imaging

Researchers have used a new ultrasound-based imaging technique, vector flow imaging, on pediatric patients for the first time, publishing their findings in Progress in Pediatric Cardiology.

Hybrid PET/MRI revealed inflammation in plaque-free arterial segments in a sizable proportion of patients with subclinical atherosclerosis, suggesting the imaging technique may provide a lens into early stages of cardiovascular disease.

A new AI software can quickly and accurately determine the manufacturer and model of a cardiac rhythm device from an x-ray, possibly speeding up treatment when the devices fail.

Intravascular ultrasound (IVUS)-guided PCI was associated with lower long-term risk of cardiac death than an angiography-guided approach in patients with complex lesions, according to a single-center study published in JACC: Cardiovascular Interventions.

Patients who received aortic valve repair or replacement (AVR) based on Class II indications fared better than those who underwent surgery for Class I triggers in a single-center study, suggesting earlier intervention may be warranted in asymptomatic individuals with chronic aortic regurgitation.

Using MRI scans to measure iron content can help specialists learn more about stroke-related damage to the brain, according to a new study published by Radiology. Should such measurements be required after patients suffer a stroke?

Radiologists commonly overlook potentially important information about a patient’s heart health when they’re performing mammograms or CT scans before starting cancer treatment, according to research set to be presented at the American College of Cardiology’s scientific sessions March 16-18 in New Orleans.

A new analysis from the PROMISE trial suggests CT angiography (CTA) may be a superior front-line diagnostic test for patients with diabetes and symptoms suggestive of coronary artery disease (CAD).

T2 mapping derived from weekly cardiac MRIs helped researchers identify cardiotoxicity at an early and reversible stage, a finding which may have implications for cancer patients at risk of chemotherapy-induced heart failure.

The Department of Energy’s National Nuclear Security Administration (NNSA) will negotiate with four U.S. companies to potentially fund molybdenum-99 (Mo-99) production without the use of highly enriched uranium.

By modifying the appropriate use criteria (AUC) for transthoracic echocardiograms (TTEs) and educating physicians on which tests should be performed in an inpatient versus outpatient setting, researchers at Bridgeport Hospital in Connecticut reduced their inpatient echo order volume by 11.1 percent and boosted the efficiency of their department.

Cardiac MRI (CMR) is rarely performed in conjunction with stress testing of heart patients—nuclear perfusion and echocardiography are far more common imaging aids—but a large new study may begin to turn the tide toward magnets as an eventual first-line diagnostic option.
