Preliminary investigation of multiparametric strain Z-score (MPZS) computation using displacement encoding with simulated echoes (DENSE) and radial point interpretation method (RPIM)

A preliminary investigation towards automated computation of Multiparametric strain Z-Score in dilated cardiomyopathy using navigator-gated spiral DENSE MRI and radial point interpolation method

An Effective 3-Dimensional Regional Myocardial Strain Computation Method with Displacement ENcoding with Stimulated Echoes (DENSE) in Dilated Cardiomyopathy Patients and Healthy Subjects

Fast Cine Displacement ENcoding with Stimulated Echoes (DENSE) is a magnetic resonance imaging (MRI) technique attributed with higher spatial resolution and rapid post-processing. Our primary goal was three-dimensional (3D) regional strains quantification using DENSE images in healthy subjects and non-ischemic, non-valvular dilated cardiomyopathy (DCM) patients, followed by validation with comp...

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...

Cine DENSE MRI with Dual Displacement Encoding

Introduction Cine DENSE (Displacement Encoding with Stimulated Echoes) MRI acquires a temporal sequence of images where the phase of each image is encoded for tissue displacement. More specifically, the phase of the DENSE stimulated-echo signal is given by θ = keΔx, where Δx is the tissue displacement and ke is the userspecified displacement-encoding frequency (a parameter analagous to the “ven...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
