Question

Quizplus · Accepted Answer

A short, wide-pelvis patient may require a CR angle in order to ensure that the entire knee is included on the image. A 7° to 10° cephalad angle will help to prevent cutoff of the knee, especially at the superior aspect near the patella. Option A is incorrect because even though there may not be a need for a large CR angle, some angle may still be necessary. Options B and D are incorrect as they do not provide enough angle to properly visualize the entire knee.
