Lung artefacts and their use.

Abstract

The science of lung ultrasound has grown tremendously over the last two decades and lung ultrasound has not only enteredthe mainstream of point of care ultrasound but has become a dominant topic. Understanding lung ultrasound signs and artifactsis critical to being able to correlate findings with actual pathology and normal anatomy and physiology. Investigators havedescribed multiple lung ultrasound artifacts and findings and it is important to understand both the physics and anatomic basisbehind them. Additionally, ultrasound machine use and transducer selection can significantly affect results obtained on patientduring an examination and the provider must carefully choose the correct settings. This manuscript describes the state of theart in ultrasound artifact recognition and correlation as well as management of ultrasound technology to optimize diagnosticsuccess.
