Quick Answer: How To Assess Rotation Inspiration Penetration In Xrays?

Rotation can be assessed by measuring the distance between the medial edges of the clavicles to the vertebral spinous processes. They should be equal or near equal. Anterior structures move the same direction as rotation so the clavicle/spinous process width is increased on the side to which the patient is rotated.

How can you tell the difference between anterior and posterior ribs?

In the inferior pair of ribs (I), the posterior rib (arrow) is slightly lower than the anterior rib. In contrast, in the cranial rib pair (S), the poste- rior rib (arrowhead) is higher than the anterior rib. Thus, the posterior ribs are farther from the film and are on the right.
