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.
[15] [16] [17] Tissue Doppler technology, the alternative method for strain rate imaging to speckle tracking technology, requires achieving sufficient parallel orientation between the direction of motion and the ultrasound beam. Its use has remained limited due to angle dependency, substantial intraobserver and interobserver variability and ...
Doppler echocardiography is a procedure that uses Doppler ultrasonography to examine the heart. [1] An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.
The timing of retirement. Sometimes the decision to retire is a regret. About one-third of retirees regretted not working longer, according to Olivia Mitchell, co-author of a paper published in ...
It is genetic, like hair or eye color. Dense breast tissue not only makes mammograms more difficult to read, but it is also a risk factor for breast cancer. Women with dense breasts have a higher ...
Sonographer doing an echocardiogram of a child Echocardiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle. Health societies recommend the use of echocardiography for initial diagnosis when a change in the patient's clinical status occurs and when new data from an echocardiogram would result in the physician changing the patient's care.

MADISON, Wis. — A 15-year-old girl who police say killed two people and wounded multiple others at a private Christian school in Wisconsin endured what appeared to be a tumultuous home life ...
