The terms tissue Doppler imaging (TDI) and tissue velocity imaging (TVI) are usually synonymous with TDE because echocardiography is the main use of tissue Doppler. Like Doppler flow, tissue Doppler can be acquired both by spectral analysis ( spectral density estimation ) as pulsed Doppler [ 1 ] and by the autocorrelation technique as colour ...
A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.In this case, the probe (or ultrasonic transducer) is placed on the chest or abdomen of the subject to get various views of the heart.
An annulus in botany is for ferns an arc or a ring of specialized cells on the sporangium. These cells are arranged in a single row, and are associated with the release or dispersal of spores. In mosses it is a ring of cells around the tip of the sporangium. In flowers it is a ring of hairs within the flower tube.
Annulus (or anulus) or annular indicates a ring- or donut-shaped area or structure. It may refer to: Human anatomy. Anulus fibrosus disci intervertebralis, spinal ...
The Doppler technique can also be used for tissue motion and velocity measurement, by tissue Doppler echocardiography. Echocardiography was also the first ultrasound subspecialty to use intravenous contrast. Echocardiography is performed by cardiac sonographers, cardiac physiologists (UK), or physicians trained in echocardiography.
WASHINGTON (Reuters) -A lead prosecutor on the criminal case accusing Donald Trump of illegally holding onto classified documents has left the U.S. Justice Department ahead of the president-elect ...
Strain rate imaging is a method in echocardiography (medical ultrasound) for measuring regional or global deformation of the myocardium (heart muscle). The term "deformation" refers to the myocardium changing shape and dimensions during the cardiac cycle.
JERUSALEM (Reuters) -The deaths of six Israeli hostages whose bodies were recovered from Gaza in August were probably linked to an Israeli airstrike against Hamas near where they were being held ...
