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.

A simple score containing four MRI markers of cerebral small vessel disease (CSVD) is associated with stroke, dementia and mortality among older adults, according to an analysis of the population-based Rotterdam Study published Oct. 24 in Stroke.

Coronary artery calcium (CAC) is predictive of all-cause and cardiovascular mortality across all racial and ethnic groups, according to a study published in the Journal of the American Heart Association—but the risk of those outcomes is significantly higher across all CAC scores for black and Hispanic patients than for whites and Asians.

Transcranial duplex sonography (TCD) can assess middle cerebral artery blood flow and provide prognostic information for stroke patients after thrombectomy for large vessel occlusions, suggests a report published Oct. 15 in Stroke.

Right ventricular (RV) strain analysis could be a useful addition to existing methods of risk assessment in patients with acute decompensated heart failure (ADHF), according to recent research that identified RV longitudinal strain from the free wall (RV-fwLS) as an independent predictor of cardiac events in the demographic.
