Long path reverberation artefact
There are many ultrasound artefacts. Here we discuss reverberation artefacts - Long path reverberation artefacts (also called A-lines in the lung)

Reverberation Artefacts
Reverberation Artefacts An ultrasound machine assumes a single pulse of ultrasound enters the tissues, is reflected off a structure, and returns directly to the transducer for interpretation. When this does not occur ultrasound artefacts are created. Not infrequently and ultrasound…

Mirror Image Artefacts
Mirror image artefact occur when ultrasound beam is not reflected directly back to the transducer after hitting a reflective surface
Comet tail artefact
Comet tail artefact is a short path reverberation artefact that weakens with each reverberation, resulting in a vertical echogenic artefact that rapidly fades as it continues in to the ultrasound image.
COPD Case 1 Lung Pulse
This patient has severe COPD and presents in extreme distress. An initial ultrasound is performed. What does this clip show?
Aortic Dissection Echocardiography
TOE is better than but TTE, but TTE can be performed first; TTE cannot exclude aortic dissection; TOE is comparable to CT and MRI for diagnostic accuracy
