Cardiac Tissue Doppler Imaging in Sports Medicine

Sports Medicine, 2007
The differentiation of training-induced cardiac adaptations from pathological conditions is a key issue in sports cardiology. As morphological features do not allow for a clear delineation of early stages of relevant pathologies, the echocardiographic evaluation of left ventricular function is the technique of first choice in this regard.

Application of Tissue Doppler Imaging in Cardiology

Cardiology, 2004
Tissue Doppler imaging (TDI) is a new echocardiographic technique employing the Doppler principle to measure the velocity of myocardial segments and other cardiac structures. It is well suited for the measurement of long-axis ventricular function. Impairment of longitudinal myocardial fiber motion is a sensitive marker of early myocardial dysfunction ...

Tissue Doppler imaging in the normal fetus

International Journal of Cardiology, 1999
Tissue Doppler imaging is a new non-invasive method that derives measurements of relaxation velocities directly from the myocardium. This approach to studying myocardial velocities offers the potential for quantitative assessment of diastolic ventricular function. Data on myocardial tissue velocities in normal fetuses have not been established.

Myocardial tissue motion influence on laser Doppler perfusion monitoring using tissue Doppler imaging

Medical & Biological Engineering & Computing, 2004
Tissue motion of the beating heart generates large movement artifacts in the laser Doppler perfusion monitoring (LDPM) signal. The aim of the study was to use tissue Doppler imaging (TDI) to localise intervals during the cardiac cycle where the influence of movement artifacts on the LDPM signal is minimum.

High frame rate tissue Doppler imaging

2001 IEEE Ultrasonics Symposium. Proceedings. An International Symposium (Cat. No.01CH37263), 2002
In tissue Doppler and strain rate imaging of the heart, a high frame rate is necessary to capture the rapid relaxations and contractions of the myocardium. Previously, the Doppler and tissue B-mode images have been calculated from different pulse transmissions. To improve the temporal resolution, we present a new acquisition technique where the Doppler

[Doppler tissue imaging in myocardial infarction].

Minerva cardioangiologica, 2001
The Doppler Tissue Imaging (DTI) is a recent Doppler method that allows to measure the velocities of myocardial walls. Thus, DTI may analyse myocardial contraction and give a quantitative evaluation of systolic and diastolic function. The aim of the study is to appraise the myocardial contraction of the left ventricle in patients with a recent ...

Automated quantification in tissue Doppler imaging

Computers in Cardiology 1998. Vol. 25 (Cat. No.98CH36292), 2002
Tissue Doppler mapping is an emerging Color Doppler imaging technology, which measures and displays the velocity of moving tissue such as the myocardium. Several clinical studies have shown that the ability to accurately measure myocardial velocity may prove a valuable diagnostic tool in characterizing regional heart function.

Arterial pulse wave velocity with tissue doppler imaging

Ultrasound in Medicine & Biology, 2002
This paper describes a new noninvasive ultrasonic method for estimating pulse wave velocity (PWV), an important physical parameter for characterizing the elastic properties of the arterial walls. The method utilizes a relatively new color Doppler modality for measuring tissue motion (tissue Doppler imaging or TDI).

Tissue Doppler Imaging in Echocardiography: Value and Limitations

Heart, Lung and Circulation, 2015
Tissue Doppler imaging (TDI) is a useful echocardiographic technique to evaluate global and regional myocardial systolic as well as diastolic function. It can also be used to quantify right ventricular and left atrial function. Recent studies have demonstrated its utility as a diagnostic as well as prognostic tool in different cardiac conditions ...

Tissue Doppler, a fundamental tool for parametric imaging

Clinical Physiology and Functional Imaging, 2004
SummaryTissue Doppler has been used for clinical applications since 1989. It has been developed from a pulsed Doppler acquisition tool towards a method where extraction of velocities can be performed from colour‐coded images. This has introduced a further development into different forms of parametric images describing different myocardial functions as
