Contrast echocardiography in the doppler color flow imaging era

I-44: Color Doppler Imaging in Impotence

Sexual impotent is very common entity and define as inability to induce or maintaining penile erection during sexual intercourse. Studies reveals about 10% of men aged 40-70 years have complete, 17% have mild and 25% have moderate amount of erectile dysfunction. The sexual impotence has different etiology including psychogenic, neurogenic, arteriogenic and venogenic causes. Current studies reve...

Doppler Contrast Echocardiography

The advent and evolution of 2D echocardiography with Doppler gave a new dimension to the evaluation of valvular heart disease (VHD) and noninvasive cardiovascular hemodynamics. Extending from basic M-mode evaluation to the more sophisticated Doppler techniques, the way one looks at the valve anatomy and physiology has changed significantly. Doppler echocardiography has become the everyday tool ...

Tissue Doppler Imaging versus Conventional Echocardiography in Evaluation of Cardiac Functions in Diabetes Mellitus

Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...

Valvular regurgitation by color Doppler echocardiography.

Orbital varix diagnosed by color Doppler flow imaging--case report.

A 66-year-old male presented with an angiographically occult orbital varix. Angiography and phlebography failed to demonstrate the lesion. Computed tomography angiography showed the varix, but not the vascular flow. Color Doppler flow imaging clearly demonstrated the well-defined varix with slow flow velocity, as well as the precise anatomical location. We recommend color Doppler flow imaging a...
