    © 2020 American College of Cardiology FoundationCoronary artery disease remains the leading cause of cardiovascular morbidity and mortality. Invasive X-ray angiography and coronary computed tomography angiography are established gold standards for coronary luminography. However, they expose patients to invasive complications, ionizing radiation, and iodinated contrast agents. Among a number of imaging modalities, coronary cardiovascular magnetic resonance (CMR) angiography may be used in some cases as an alternative for the detection and monitoring of coronary arterial stenosis, with advantages including its versatility, excellent soft tissue characterization, and avoidance of ionizing radiation and iodinated contrast agents. In this review, we explore the recent advances in motion correction, image acceleration, and reconstruction technologies that are bringing coronary CMR angiography closer to widespread clinical implementation.

    The effects of equal pay laws on firm pay premiums: Evidence from Chile
    (Elsevier B.V., 2022) Cruz G.; Rau T.
    © 2022This paper analyzes Chile's 2009 Equal Pay for Equal Work Law (EPL) and its effects on firm pay premiums. The law affected firms with 10 or more workers and specified penalties by firm size, including a disclosure requirement for firms with 200 or more workers. We use matched employer-employee data to estimate worker-firm fixed-effects models, decomposing the firm's contribution to the gender pay gap into bargaining power and sorting channels. The EPL reduces the firm premium gender gap by 6.1%, driven by the bargaining power channel. The effects are larger in firms exposed to higher penalties and disclosure requirements.
