Interplatform reproducibility of liver and spleen stiffness measured with MR elastography.
T.K. Yasar,Mathilde Wagner,Octavia Bane,Cecilia Besa,James S. Babb,Stephan Kannengiesser,Maggie Fung,Richard L. Ehman,Bachir Taouli +8 more
TL;DR: To assess interplatform reproducibility of liver stiffness (LS) and spleen stiffness (SS) measured with magnetic resonance elastography (MRE) based on a 2D gradient echo (GRE) sequence.

Magnetic Resonance Elastography of the Liver: Qualitative and Quantitative Comparison of Gradient Echo and Spin Echo Echoplanar Imaging Sequences.
Mathilde Wagner,Cecilia Besa,Jad Bou Ayache,T.K. Yasar,Octavia Bane,Maggie Fung,Richard L. Ehman,Bachir Taouli +7 more
TL;DR: The data suggest that SE-EPI-M RE may be a better alternative to GRE-MRE for detection of liver fibrosis and Reproducibility of LS values between the 2 sequences was excellent.

MR imaging of synchronous spin motion and strain waves
Richard L. Ehman
- 19 Oct 1995
TL;DR: In this paper, an alternating magnetic field gradient synchronized with the applied stress is employed in the NMR imaging pulse sequence to detect and measure synchronous spin motion throughout the field of view.

Cardiac magnetic resonance fluoroscopy.
Josef P. Debbins,Stephen J. Riederer,Phillip J. Rossman,Roger C. Grimm,Joel P. Felmlee,Jerome F. Breen,Richard L. Ehman +6 more
TL;DR: The cardiac fluoroscopy technique provides an approximate eightfold reduction in the time required to obtain subject‐specific double oblique sections and an independent graphical user interface facilitates interactive control of section localization and contrast by permitting pulse sequence parameter modification during scanning.

Pelvic imaging with phased-array coils: quantitative assessment of signal-to-noise ratio improvement.
TL;DR: The signal‐to‐noise ratios (S/Ns) of two different pelvic magnetic resonance imaging phased arrays were compared with that of the body coil to demonstrate the enhanced imaging capability of the phased arrays.
