Thoracic Ultrasound

Pleural Effusions

Phased Array

ultrasound sensor position for pleural effusion


So here’s another example of interrogating the right inferior thoracic space in a coronal plane, in this case using a phased array probe placed at the right flank. You can tell it’s a phased array probe because it comes from that point at the top of the screen and this is actually a pretty helpful probe for getting in between ribs. In this case we can see the liver, kidney, the diaphragm, and you can see that triangular wedge shaped area of black which is fluid or pleural effusion and you can actually see what we call the spine sign, which is the proximal thoracic ribs or lateral vertebral processes extending up from behind the liver into the thoracic area.
