- Myocardial T1 mapping: application to patients with acute and chronic myocardial infarctionDaniel R Messroghli
BHF Cardiac MRI Unit, Leeds General Infirmary, Leeds, UK
Magn Reson Med 58:34-40. 2007..Precontrast T(1) maps enable the detection of acute MI. Acute and chronic MI show different patterns of T(1) changes. Standardized T(1) thresholds provide the potential to dichotomously identify areas of infarction...

BHF Cardiac MRI Unit, Leeds General Infirmary, Leeds, UK
Magn Reson Med 52:141-6. 2004..The region of infarction was clearly visualized. MOLLI provides high-resolution T1 maps of human myocardium in native and post-contrast situations within a single breath-hold...
- An open-source software tool for the generation of relaxation time maps in magnetic resonance imagingDaniel R Messroghli
Cardiac MRI Unit, Franz Volhard Klinik, Charite University Medicine, Berlin, Germany
BMC Med Imaging 10:16. 2010..Such a software program would allow researchers to test and compare new imaging strategies and thus would significantly facilitate research in the area of quantitative tissue characterization...

BHF Cardiac MRI Unit, Leeds General Infirmary, England
Radiology 238:1004-12. 2006..This technique could enable direct quantification of changes in tissue characteristics in ischemic and inflammatory myocardial diseases...
- The reproducibility of left ventricular volume and mass measurements: a comparison between dual-inversion-recovery black-blood sequence and SSFPSarah Clay
Leeds General Infirmary, BHF Cardiac MRI Unit, B Floor, Clarendon Wing, Great George Street, Leeds, LS1 3EX, UK
Eur Radiol 16:32-7. 2006..For studies requiring LV mass measurements, the dual-inversion-recovery BB sequence offers improved spatial resolution and improved reproducibility to SSFP...
- Assessment of regional left ventricular function: accuracy and reproducibility of positioning standard short-axis sections in cardiac MR imagingDaniel R Messroghli
British Heart Foundation Cardiac MRI Unit, Leeds General Infirmary, Leeds, England
Radiology 235:229-36. 2005..The proposed method produces standardized short-axis section positions that meet the recommendations for cardiac imaging. The study was approved by the local ethics committee, and all subjects gave written informed consent...
- Small animal Look-Locker inversion recovery (SALLI) for simultaneous generation of cardiac T1 maps and cine and inversion recovery-prepared images at high heart rates: initial experienceDaniel R Messroghli
Department of Congenital Heart Defects, Deutsches Herzzentrum Berlin, Berlin, Germany
Radiology 261:258-65. 2011..To develop a single magnetic resonance (MR) imaging approach for comprehensive assessment of cardiac function and tissue properties in small animals with high heart rates...
- T1 mapping in patients with acute myocardial infarctionDaniel R Messroghli
Franz Volhard Clinic, Medical Faculty of the Charite, Humboldt University of Berlin, Germany
J Cardiovasc Magn Reson 5:353-9. 2003..T1 mapping can detect myocardial necrosis without the use of contrast media. Information that can be extracted from a combination of pre- and postcontrast T1 maps exceeds that from conventional contrast studies...
