Due to the procedure being invasive, sonographers do not perform this procedure unlike transthoracic echo. [citation needed] Once adequate sedation and anesthesia are achieved, the probe is passed through the mouth and into the esophagus. From here, the protocol used for the procedure is highly variable.
It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo. Echocardiography is routinely used in the diagnosis, management, and follow-up of patients with any suspected or known heart diseases. It is one of the ...
This method exploits the susceptibility differences between tissues and uses a fully velocity-compensated, three-dimensional, RF-spoiled, high-resolution, 3D-gradient echo scan. This special data acquisition and image processing produces an enhanced contrast magnitude image very sensitive to venous blood, hemorrhage and iron storage.
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.

Steady-state free precession imaging (SSFP) or balanced SSFP is an MRI technique which uses short repetition times (TR) and low flip angles (about 10 degrees) to achieve steady state of longitudinal magnetizations as the magnetizations does not decay completely nor achieving full T1 relaxation. [1] While spoiled gradient-echo sequences refer to ...

These post-dispatch and pre-arrival instructions are intended both to keep the caller and the patient safe, but also, where necessary, to turn the caller into the "first first responder" by giving them potentially life-saving instructions. They include: cardiopulmonary resuscitation for adults, children, babies, and newborns; the use of a ...
