In a right anterior oblique (RAO) projection of a single contrast colon, the patient will be rotated laterally by how many degrees?

In a right anterior oblique (RAO) projection for a single contrast colon study, the patient should be rotated laterally between 35 to 45 degrees. This degree of rotation is essential for optimal visualization of the colonic anatomy, particularly to enhance the view of the right colic flexure and the ascending colon. The correct angulation allows for a sufficiently comprehensive perspective, reducing superimposition of structures and improving diagnostic accuracy.

The rotation helps to position the colon in a way that facilitates the contrast material's distribution, ensuring clarity in imaging. The range of 35 to 45 degrees strikes a balance between providing adequate out-of-plane separation of the bowel loops and ensuring the region of interest is well visualized.

Other ranges, such as those below or above this specified range, would either not provide the necessary detail or might make the anatomy more difficult to interpret due to overlapping structures.
