Cardiovascular imaging plays a central role in the diagnosis and treatment of cardiovascular disease. Recently, increased emphasis has been placed on quality in cardiovascular imaging, and it is becoming a central priority for various stakeholders, including patients, physicians, and payers. The changing health care landscape and associated challenges imposed on cardiac imagers, including reductions in reimbursement and growing need for pre-authorization, have also helped bring quality metrics to the forefront....

Coronary CT angiography (CTA) is a reliable tool for the detection of coronary artery disease (CAD) that conveys significant prognostic information. It does not provide data on the hemodynamic significance of a given lesion, particularly in intermediate-grade stenosis....
Acute chest pain (ACP) represents a clinical as well as economic challenge, often resulting in time-consuming, expensive evaluations to avoid missed diagnosis of acute coronary syndromes (ACSs). Coronary CT angiography (CTA) is an attractive noninvasive technique for use in the emergency department (ED) due to its high accuracy and negative predictive value.
Due to the discrepancy between higher symptom burden and lower disease prevalence, the diagnosis of coronary artery disease (CAD) in women is challenging. Cardiac CT can be particularly useful in CAD diagnosis and risk stratification in women.
We sought to study the feasibility of establishing a comprehensive, mostly self-directed yoga program in a hospital and its dose-effect relationship on cardiovascular risk factors and quality of life (QoL) measures over six months.
Previous small-scale studies with carefully controlled scan protocols report that CT scanners that facilitate prospectively triggered scanning and provide high-pitch spiral CT scan modes drastically lower radiation doses. However, diagnostic reference levels should be selected by medical bodies on the basis of large surveys of representative sites and reviewed at appropriate time intervals.
