Evaluation of Cardiac Masses:
A Tweetorial for #FITSurvivalGuide 🚨 #ACCImaging @ASE360 @SCMR @journalofCMR @ACCinTouch
Dedicated:@dr_chirumamilla & all #ACCFIT in #CardioTwitter
Main Ref: link.springer.com/article/10.100… Palaskas, et al. Curr Treat Options Cardio Med (2018) 20: 29.
Usually, it all starts with an abnormal finding in an echo suggestive of intracavitary mass. How can we tell one from the other? It can be confusing.
For artifacts, I did a Tweetorial already that describes the most common ones. Basic understanding of ultrasound physics is needed to be able to explain them: twitter.com/i/moments/1030…

Artifacts in a nutshell 👽👾

A Tweetorial...
Dedicated to @bcostelloMD, @RezaEmaminia & all the great #FITs stressed out by #EchoBoards @ASE360 #carrotsquad
Images and some of the content from Bertrand, et al. JASE 2016;29:381-91. onlinejase.com/article/S0894-…
Ultrasound waves need a media to travel. Our tissues are that media. All tissues have different acoustic impedances. Air, fat, water, blood, muscle, bone listed in increasing impedance. Always there will be reflected & refracted waves as it traverses different tissue layers.
Remember that the way the US distributes the waves in a phased array probe is similar to a folding fan, so reflection (rebound) & refraction (change in direction) occurs across the sector width (Triangle area where you see the images) look at panel B of above figure.
