    30-minute CMR for common clinical indications: a Society for Cardiovascular Magnetic Resonance white paper
    (BMC, 2022-03-01) Raman, Subha V.; Markl, Michael; Patel, Amit R.; Bryant, Jennifer; Allen, Bradley D.; Plein, Sven; Seiberlich, Nicole; Medicine, School of Medicine
    Background: Despite decades of accruing evidence supporting the clinical utility of cardiovascular magnetic resonance (CMR), adoption of CMR in routine cardiovascular practice remains limited in many regions of the world. Persistent use of long scan times of 60 min or more contributes to limited adoption, though techniques available on most scanners afford routine CMR examination within 30 min. Incorporating such techniques into standardize protocols can answer common clinical questions in daily practice, including those related to heart failure, cardiomyopathy, ventricular arrhythmia, ischemic heart disease, and non-ischemic myocardial injury. BODY: In this white paper, we describe CMR protocols of 30 min or shorter duration with routine techniques with or without stress perfusion, plus specific approaches in patient and scanner room preparation for efficiency. Minimum requirements for the scanner gradient system, coil hardware and pulse sequences are detailed. Recent advances such as quantitative myocardial mapping and other add-on acquisitions can be incorporated into the proposed protocols without significant extension of scan duration for most patients. Conclusion: Common questions in clinical cardiovascular practice can be answered in routine CMR protocols under 30 min; their incorporation warrants consideration to facilitate increased access to CMR worldwide.

    Society for Cardiovascular Magnetic Resonance (SCMR) guidance for re-activation of cardiovascular magnetic resonance practice after peak phase of the COVID-19 pandemic
    (Springer Nature, 2020-08-10) Allen, Bradley D.; Wong, Timothy C.; Bucciarelli-Ducci, Chiara; Bryant, Jennifer; Chen, Tiffany; Dall’Armellina, Erica; Finn, J. Paul; Fontana, Marianna; Francone, Marco; Han, Yuchi; Hays, Allison G.; Jacob, Ron; Lawton, Chris; Manning, Warren J.; Ordovas, Karen; Parwani, Purvi; Plein, Sven; Powell, Andrew J.; Raman, Subha V.; Salerno, Michael; Carr, James C.; Medicine, School of Medicine
    During the peak phase of the COVID-19 pandemic, alterations of standard operating procedures were necessary for health systems to protect patients and healthcare workers and ensure access to vital hospital resources. As the peak phase passes, re-activation plans are required to safely manage increasing clinical volumes. In the context of cardiovascular magnetic resonance (CMR), re-activation objectives include continued performance of urgent CMR studies and resumption of CMR in patients with semi-urgent and elective indications in an environment that is safe for both patients and health care workers.

    Society for Cardiovascular Magnetic Resonance (SCMR) guidance for the practice of cardiovascular magnetic resonance during the COVID-19 pandemic
    (BioMed Central, 2020-04-27) Han, Yuchi; Chen, Tiffany; Bryant, Jennifer; Bucciarelli-Ducci, Chiara; Dyke, Christopher; Elliott, Michael D.; Ferrari, Victor A.; Friedrich, Matthias G.; Lawton, Chris; Manning, Warren J.; Ordovas, Karen; Plein, Sven; Powell, Andrew J.; Raman, Subha V.; Carr, James; Medicine, School of Medicine
    The aim of this document is to provide general guidance and specific recommendations on the practice of cardiovascular magnetic resonance (CMR) in the era of the COVID-19 pandemic. There are two major considerations. First, continued urgent and semi-urgent care for the patients who have no known active COVID-19 should be provided in a safe manner for both patients and staff. Second, when necessary, CMR on patients with confirmed or suspected active COVID-19 should focus on the specific clinical question with an emphasis on myocardial function and tissue characterization while optimizing patient and staff safety.
