Journal ArticleDOI
Myocardial T1 mapping and extracellular volume quantification: a Society for Cardiovascular Magnetic Resonance (SCMR) and CMR Working Group of the European Society of Cardiology consensus statement
James C. Moon,Daniel Messroghli,Peter Kellman,Stefan K. Piechnik,Matthew D. Robson,Martin Ugander,Peter D. Gatehouse,Andrew E. Arai,Matthias G. Friedrich,Stefan Neubauer,Jeanette Schulz-Menger,Jeanette Schulz-Menger,Erik B. Schelbert +12 more
TL;DR: This document provides recommendations for clinical and research T1 and ECV measurement, based on published evidence when available and expert consensus when not, and addresses controversies in the field.
Journal ArticleDOI
Phase-sensitive inversion recovery for detecting myocardial infarction using gadolinium-delayed hyperenhancement.
TL;DR: Experimental results are presented which demonstrate the benefits of both phase‐sensitive IR image reconstruction and surface coil intensity normalization for detecting myocardial infarction (MI).
Journal ArticleDOI
Retrospective Determination of the Area at Risk for Reperfused Acute Myocardial Infarction With T2-Weighted Cardiac Magnetic Resonance Imaging Histopathological and Displacement Encoding With Stimulated Echoes (DENSE) Functional Validations
Anthony H. Aletras,Gauri S. Tilak,Alex Natanzon,Li-Yueh Hsu,Felix M. Gonzalez,Robert F. Hoyt,Andrew E. Arai +6 more
TL;DR: Findings are consistent with the premise that the T2 abnormality depicts the area at risk, a zone of reversibly and irreversibly injured myocardium associated with reperfused subendocardial infarctions.
Journal ArticleDOI
Extracellular volume imaging by magnetic resonance imaging provides insights into overt and sub-clinical myocardial pathology
Martin Ugander,Abiola J Oki,Li-Yueh Hsu,Peter Kellman,Andreas Greiser,Anthony H. Aletras,Christopher T. Sibley,Marcus Y. Chen,W. Patricia Bandettini,Andrew E. Arai +9 more
TL;DR: Extracellular volume fraction imaging can quantitatively characterize myocardial infarction, atypical diffuse fibrosis, and subtleMyocardial abnormalities not clinically apparent on LGE images.
Journal ArticleDOI
Ionizing radiation in cardiac imaging: a science advisory from the American Heart Association Committee on Cardiac Imaging of the Council on Clinical Cardiology and Committee on Cardiovascular Imaging and Intervention of the Council on Cardiovascular Radiology and Intervention
Thomas C. Gerber,J. Jeffrey Carr,Andrew E. Arai,Robert L. Dixon,Victor A. Ferrari,Antoinette S. Gomes,Gary V. Heller,Cynthia H. McCollough,Michael F. McNitt-Gray,Fred A. Mettler,Jennifer H. Mieres,Richard L. Morin,Michael V. Yester +12 more
TL;DR: A preliminary report on medical radiation exposures to the US population based on publicly available sources of data estimated that the collective dose received from medical uses of radiation has increased by >700% between 1980 and 2006.
