How do I identify my carina?
Traditionally, the carina has been located by the radiologist either by taking the position as the middle of the T4-T5 interspace; or by using the Dee Method, which involves identifying the aortic arch and then drawing a line inferomedially through the middle of the arch at a 45-degree angle to the midline.
Is carina a cartilage?
