  2. Transthoracic echocardiogram - Wikipedia

    en.wikipedia.org/wiki/Transthoracic_echocardiogram

    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.

  3. Transesophageal echocardiogram - Wikipedia

    en.wikipedia.org/wiki/Transesophageal_echocardiogram

    A transesophageal echocardiogram (TEE; also spelled transoesophageal echocardiogram; TOE in British English) is an alternative way to perform an echocardiogram. A specialized probe containing an ultrasound transducer at its tip is passed into the patient's esophagus. [1] This allows image and Doppler evaluation which can be recorded. It is ...

    The test score is the time taken on the test, in minutes. This can also be converted to an estimated maximal oxygen uptake score using the calculator below and the following formulas, where the value "T" is the total time completed (expressed in minutes and fractions of a minute e.g. 9 minutes 15 seconds = 9.25 minutes).

  5. Echocardiography - Wikipedia

    en.wikipedia.org/wiki/Echocardiography

    A standard echocardiogram is also known as a transthoracic echocardiogram (TTE) or cardiac ultrasound, and it is used for rapid evaluation of a patient at their bedside. [9] [10] In this case, the echocardiography transducer (or probe) is placed on the chest wall (or thorax) of the subject, and images are taken through the chest wall. This is a ...

  6. Aortic dissection - Wikipedia

    en.wikipedia.org/wiki/Aortic_dissection

    The transesophageal echocardiogram (TEE) is a good test in the diagnosis of aortic dissection, with a sensitivity up to 98% and a specificity up to 97%. It has become the preferred imaging modality for suspected aortic dissection. It is a relatively noninvasive test, requiring the individual to swallow the echocardiography probe.

  7. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.

  8. Contrast-enhanced ultrasound - Wikipedia

    en.wikipedia.org/wiki/Contrast-enhanced_ultrasound

    A bubble echocardiogram is an extension of this that uses simple air bubbles as a contrast medium during this study and often has to be requested specifically. Although colour Doppler can be used to detect abnormal flows between the chambers of the heart (e.g., persistent (patent) foramen ovale ), it has a limited sensitivity .
