This is an image of the RUQ, showing a pleural effusion. For orientation, the head is to the left of the screen and the feet are to the right of the screen.

This is an example of pleural effusion. If the lung is full of air (normal) then you shouldn’t see the spine superior to the diaphragm. Air obscures the spine usually. In this case, we see the spine marching past the diaphragm indicating there is fluid present.
