Comparison of local sine wave modelling with harmonic phase analysis for the assessment of circumferential myocardial strain from tagged cardiovascular magnetic resonance images
نویسندگان
چکیده
Background Assessment of regional ventricular deformation is more sensitive than ejection fraction (EF) for detecting myocardial dysfunction. We sought to compare a local sinewave modelling (SinMod) method with the more established harmonic phase analysis (HARP) technique, for assessment of Lagrangian left ventricular (LV) peak systolic circumferential strain (εcc) from tagged cardiovascular magnetic resonance images, in patients with cardiomyopathies and healthy volunteers. The variability and rapidity of each technique, and the effect of contrast, were also assessed.

Comparison of local sine wave modeling with harmonic phase analysis for the assessment of myocardial strain.
PURPOSE To compare local sine-wave modeling (SinMod) with harmonic phase analysis (HARP), for assessment of left ventricular (LV) circumferential strain (εcc) from tagged cardiovascular magnetic resonance images. MATERIALS AND METHODS Mid-ventricular spatial modulation of magnetization was performed in 60 participants (15 each with hypertrophic, dilated or ischemic cardiomyopathy and 15 healt...
متن کاملThree-dimensional regional strain analysis in porcine myocardial infarction: a 3T magnetic resonance tagging study
BACKGROUND Previous studies of mechanical strain anomalies in myocardial infarction (MI) have been largely limited to analysis of one-dimensional (1D) and two-dimensional (2D) strain parameters. Advances in cardiovascular magnetic resonance (CMR) methods now permit a complete three-dimensional (3D) interrogation of myocardial regional strain. The aim of this study was to investigate the increme...
متن کاملCharacterization of three-dimensional myocardial deformation in the mouse heart: an MR tagging study.
PURPOSE To develop a 3D MR tagging method that combines harmonic phase (HARP) and homogeneous strain analysis methods for quantification of regional myocardial wall motion in mice. MATERIALS AND METHODS 3D tagged images were acquired from seven C57BL/6 mice. Intersecting tag points were reconstructed and 3D strains were quantified at apical, midventricular, and basal levels. Circumferential a...
متن کاملArtifacts reduction in strain maps of tagged magnetic resonance imaging using harmonic phase
Tagged Magnetic Resonance Imaging (MRI) is a noninvasive technique for examining myocardial function and deformation. Tagged MRI can also be used in quasi-static MR elastography to acquire strain maps of other biological soft tissues. Harmonic phase (HARP) provides automatic and rapid analysis of tagged MR images for the quantification and visualization of myocardial strain. We propose a new ar...
متن کاملCardiac motion tracking using CINE harmonic phase (HARP) magnetic resonance imaging.
This article introduces a new image processing technique for rapid analysis of tagged cardiac magnetic resonance image sequences. The method uses isolated spectral peaks in SPAMM-tagged magnetic resonance images, which contain information about cardiac motion. The inverse Fourier transform of a spectral peak is a complex image whose calculated angle is called a harmonic phase (HARP) image. It i...
