Tissue Doppler imaging in Fabry disease

Current Opinion in Cardiology, 2004
The development of effective enzyme replacement/enhancement therapy makes of clinical relevance considering Fabry disease in the differential diagnosis of patients with hypertrophic cardiomyopathy. In particular the opportunity to significantly modify the clinical progression of the disease has reinforced the need for early diagnosis of Fabry ...

Tissue Doppler Imaging Reproducibility during Exercise

International Journal of Sports Medicine, 2008
Tissue Doppler imaging (TDI) is an echocardiographic technique used during exercising to improve the accuracy of a cardiovascular diagnostic. The validity of TDI requires its reproducibility, which has never been challenged during moderate to maximal intensity exercising. The present study was specifically designed to assess the transmitral Doppler and

Pulsed doppler tissue imaging in dystrophinopathic cardiomyopathy

Journal of the American Society of Echocardiography, 2002
Cardiac dysfunction is a primary feature in patients and female carriers of Becker muscular dystrophy (BMD). Conventional echocardiography and pulsed Doppler tissue imaging (DTI) were performed in 28 patients with BMD, in 20 female carriers, and in 38 control participants (20 men and 18 women). Left ventricular ejection fraction (LVEF) was lower in BMD

GPU Based Tissue Doppler Imaging

2011 5th International Conference on Bioinformatics and Biomedical Engineering, 2011
Tissue Doppler imaging is a routinely used diagnostic tool for assessing myocardial function in real time. The required signal processing is computationally intensive, including modified auto-correlation, scan conversion, image mapping. Parallel algorithms and implementations based on GPU platform are proposed in this paper to increase the computation ...

Bandwidth Doppler Tissue Imaging (BDTI)

2009 IEEE International Ultrasonics Symposium, 2009
Doppler Tissue Imaging (DTI), as used at present, is angle-dependent. in that it only measures the velocity component along the ultrasound beam direction. There is an ongoing need in cardiology for imaging and measurement techniques which are angle-independent.

Technological advances in tissue Doppler imaging echocardiography

Heart, 2008
Tissue Doppler imaging is a recently introduced echocardiographic tool for measuring myocardial velocities. In this article the physical principles and different myocardial velocity imaging modalities are discussed. Examples of practical applications and clinical use of this non-invasive imaging technique are provided.

Ultra-high Frame Rate Tissue Doppler Imaging

Ultrasound in Medicine & Biology, 2014
We describe a new tissue Doppler imaging (TDI) method, ultra-high frame rate tissue Doppler imaging (UFR-TDI). With two broad transmit beams covering only the ventricular walls, we achieve 1200 frames/s in a four-chamber apical view. We examined 10 healthy volunteers to study the feasibility of this method.
