  2. Focused assessment with sonography for trauma - Wikipedia

    en.wikipedia.org/wiki/Focused_assessment_with_s...

    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.

  3. Focus assessed transthoracic echocardiography - Wikipedia

    en.wikipedia.org/wiki/Focus_assessed_trans...

    The original focused cardiac ultrasound protocol for non-cardiologists was devised by Dr Erik Sloth in 1989 and has formed the basis of hands-on FATE courses ever since. The success of the original protocol has inspired a surge of replicas in many shapes and the coining of many imaginative acronyms: FEER, FEEL, Focus, Bleep, HART, FUSE etc.

  4. Emergency ultrasound - Wikipedia

    en.wikipedia.org/wiki/Emergency_ultrasound

    A portable ultrasound machine used in the prehospital setting. Emergency ultrasound is used to quickly diagnose a limited set of injuries or pathologic conditions, [4] specifically those where conventional diagnostic methods would either take too long or would introduce greater risk to a person (either by transporting the person away from the most closely monitored setting, or exposing them to ...

  5. Transjugular intrahepatic portosystemic shunt - Wikipedia

    en.wikipedia.org/wiki/Transjugular_intrahepatic...

    A TIPS procedure decreases the effective vascular resistance of the liver through the creation of an alternative pathway for portal venous circulation. By creating a shunt from the portal vein to the hepatic vein, this intervention allows portal blood an alternative avenue for draining into systemic circulation.

  6. 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.

  7. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.

  8. Anomaly scan - Wikipedia

    en.wikipedia.org/wiki/Anomaly_scan

    The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]

  9. Doppler ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Doppler_ultrasonography

    Ultrasound duplex scanning can provide additional information that may guide therapeutic decisions. The location and severity of arterial narrowings and occlusions can be identified. The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity ...
