An endoscopic ultrasound probe placed in the esophagus can also be used to visualize lymph nodes in the chest surrounding the airways (bronchi), which is important for the staging of lung cancer. Ultrasound can also be performed with an endoscopic probe inside the bronchi themselves, a technique known as endobronchial ultrasound .
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]
Then, I went in for the scan. The MRI machine looked pretty standard, except that there was a screen with Netflix queued up. ... Esophagus. Stomach. Liver (they can see if the liver is enlarged or ...
The endoscope is then passed over the tongue and into the oropharynx. This is the most uncomfortable stage for the patient. Quick and gentle manipulation under vision guides the endoscope into the esophagus. The endoscope is gradually advanced down the esophagus making note of any pathology.
In medicine, Esophageal Doppler or Oesophageal Doppler uses a small ultrasound probe inserted into the esophagus through the nose or mouth to measure blood velocity in the descending aorta. It is minimally invasive (does not break the skin) and is used to derive hemodynamic parameters such as stroke volume (SV) and cardiac output (CO).
Transnasal esophagoscopy is an office based procedure in which the patient is anesthetized locally in the nose and sometimes the oropharynx.The scope is advanced into the ipsilateral pyriform sinus and through the esophageal inlet to the stomach, where the esophagus can be examined, with special attention paid to the gastroesophageal (GE) junction.

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.
The main risks are infection, over-sedation, perforation, or a tear of the stomach or esophagus lining and bleeding. [10] Although perforation generally requires surgery, certain cases may be treated with antibiotics and intravenous fluids. Bleeding may occur at the site of a biopsy or polyp removal.
