Rotational motion of Left Ventricle by Harmonic Phase on radial tagging
Background The rotational motion of the Left Ventricle (LV) is a valuable measure in assessment of cardiac mechanics and can be estimated best through radial tagging. For practical quantitative application of this newly developed sequence, corresponding analyzing tools need to be developed. In this study, we presented a processing method based on peak-combination Harmonic Phase (HARP) approach ...
متن کاملTwist measurement of the left ventricle through radial tagging
Methods Short axis radially tagged images were acquired at apical and basal levels in 6 healthy subjects. Contouring LV epicardial and endocardial borders is the only user interaction in the twist extraction process. Applying a proper threshold algorithm over the masked images results in binary images containing easily detectable tags. We tracked the mean position of tags over the cardiac cycle...
متن کاملSex-related Left Ventricle Rotational and Torsional Mechanics by Block Matching Algorithm
Background: The aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age.Materials and Methods: In this analytical study, twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angel...
متن کاملRegional rotation of the left ventricle in healthy and cardiomyopathic subjects measured with radial myocardial tagging
Background Left ventricular rotational deformation, which arises from contraction of myofibers arranged in a helical structure, plays a crucial role in cardiac mechanics. Myocardial dysfunction in cardiomyopathies is usually associated with altered diastolic rotation [1-3]. However, regional myocardial abnormalities in various cardiomyopathies may result in regional alterations of both systolic...
