The use of intravascular ultrasound (IVUS) to guide PCI leads to further improvements in event-free survival between one and two years post-procedure, according to a report from the ADAPT-DES study published in Circulation: Cardiovascular Interventions.

As 3D printing continues to gain traction as a medical treatment tool, cardiologists across the globe are implementing the technology in their own departments and practices. But as they do, one radiologist cautions, it’s important they consider some critical groundwork that’s yet to be laid.

The shortage of Molybdenum-99 (Mo-99), which is used to create the crucial nuclear imaging radioisotope Technetium-99m, is expected to improve in the coming weeks.

A new study aims to evaluate whether medical professionals with no ultrasound experience can use artificial intelligence (AI) software to capture high-quality echocardiograms, potentially opening the door to greater testing in primary care settings.

Critical shortages of imaging equipment and qualified radiologists left an estimated 56,000 angina patients without access to potentially lifesaving computed tomography (CT) scans last year, the Royal College of Radiologists and British Society of Cardiovascular Imaging announced Nov. 8.

Nuclear medicine clinics could be operating at 25 percent capacity or less by the end of the week due to a shortage of Technetium-99m, said one hospital leader.

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.

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.

Patients with normal arteries upon coronary CT angiography (CTA) experienced either death or myocardial infarction at a rate of 0.04 percent per year, according to a study with 10 years of follow-up published in JACC: Cardiovascular Imaging.

Cardiac MRI can accurately diagnose pulmonary hypertension (PH) without the invasiveness of right-sided heart catheterization (RHC), suggests a new study published in Radiology.
