Sternum & SC Joints: Radiographic Anatomy - Video Lesson

Hey, everybody. Welcome to today's lesson on radiographic anatomy, demonstrated on routine projections of the sternum and SC joints. In a previous lesson, we discussed the anatomy of the sternum and SC joints and which radiographic projections are routinely performed. So let's tie that information to the radiographs themselves. As a reminder, the routine radiographic projections of the sternum are PA oblique, RAO position, and lateral. And the routine radiographic projections of the SC joints are PA and right and left PA obliques. Let's start with the first image. What projection is being demonstrated here? Let's take a look. This is a PA oblique sternum radiograph. We know this because the sternum is visualized alongside the vertebral column superimposed on the heart shadow with no superimposition of the vertebrae. Remember, this is an RAO position, but a PA oblique projection. What about the
