MRI of Longitudinal Myocardial Strain using Multislice Cine DENSE with Through-plane Displacement Encoding
Introduction Cine DENSE (Displacement Encoding with Stimulated Echoes) is a quantitative MRI method for imaging myocardial displacement and strain. Typically, cine DENSE images of the heart are acquired in a short-axis plane, and the in-plane circumferential and radial displacements and strains are measured. However, quantitative imaging of longitudinal myocardial motion is also important, as i...
متن کاملComparison of 2D and 3D calculation of left ventricular torsion as circumferential-longitudinal shear angle using MRI tagging
Background: Left ventricular (LV) torsion can be described as the circumferential-longitudinal (CL) shear angle. This method allows for torsion to be comparable between patients since it incorporates LV size. Furthermore it is most related to the fiber orientations in the myocardial wall. The CL shear angle can be calculated from 2D or 3D datasets, where the 3D approach is closest to the true s...
متن کاملMeasurements of left ventricular myocardial longitudinal systolic displacement using spectral and colour tissue Doppler: time for a reassessment?
BACKGROUND Echocardiographic measurements of left ventricular (LV) myocardial displacement may produce different results depending on the choice of employed modality and subjective adjustments during data acquisition and analysis. METHODS In this study, left ventricular longitudinal systolic displacement was quantified in 57 patients (31 women and 26 men, 50 +/- 16 years) using colour (colour...
متن کاملAssessment of Left Ventricular Myocardial T1 Hyperintesity in Patients with Suspected Cardiac Amyloidosis using MRI
Figures 2a and 2b – Pre-contrast T1-GRE in normal controls (left) as compared to suspected amyloid (right). SNR and CNR are higher in the amyloid group both quantitatively and qualitatively (p<0.05). Figure 3 Left: MRI of Amyloid cadaveric heart (above in both pictures) and normal cadaveric heart (below). Right: Calculated T1 of the respective hearts. Amyloid cadaveric heart has mean T1 of 345....
متن کاملNoninvasive quantification of left ventricular rotational deformation in normal humans using magnetic resonance imaging myocardial tagging.
It has been postulated that rotation of the left ventricular apex with respect to the base is a component of normal systolic function in humans, but it has been difficult to measure it noninvasively. Tagging is a new magnetic resonance imaging technique that labels specific areas of myocardium by selective radio-frequency excitation of narrow planes orthogonal to the imaging plane before acquir...
