1123 Cardiac MR elastography: observation of stiffness-related shear-wave amplitude variations in 6 healthy volunteers
2008
Journal of Cardiovascular Magnetic Resonance
It is proposed that in vivo time-resolved cardiac magnetic resonance elastography (MRE) enables noninvasive assessment of myocardial pressure changes. Therefore, an experiment is developed that identifies variations in myocardial stiffness during the heart cycle by measuring changes in externally induced shear-wave amplitudes. Methods Six healthy male volunteers underwent in vivo cardiac MRE on a clinical 1.5 T scanner. An ECG-gated, motionsensitized and segmented spoiled GRE-MRE sequence was
