Echography/ Ultrasound

Examen échographie, Imagerie La Chaux-de-Fonds

Echography is a painless and non-invasive imaging technique using ultrasound. The images produced are viewed in real-time and allow the different organs as well as the vessels and the speed of blood flow inside a vein or artery to be assessed (Doppler-echography). A gel is applied between the skin and the probe to prevent air from interrupting the transmission of the ultrasound waves.

Allow between 30 to 45 minutes


  • For any upper abdomen examinations, please come on an empty stomach.
  • For examinations of the whole abdomen, it is necessary to come on an empty stomach and have a full bladder. The amount of water to drink to have a full bladder varies from person to person. It is recommended to drink between 5dl and 1l one hour before the examination and pass water.
  • For this imaging modality, the part of the body to be examined must be completely uncovered (pay attention to girdles, compression stockings, cast, splints, tape, etc.)
