Q

Oblique Position

A

Slanted position where the patient is lying at an angle neither prone nor supine. In radiology you may see right anterior oblique (RAO), left anterior oblique (LAO), Right posterior oblique (RPO), or left posterior oblique (LPO). The anterior or posterior terminology indicates the part of the body closer to the film. For example, in RAO, a person is on his right side with the anterior part of the body closer to the film.

Q

Computed Tomography (CT)

A

Using specialized equipment, two dimensional X-ray images are taken around a single axis of rotation. The images are combined to create a three dimensional image or picture of the inside of the body. These cross sectional images of the area being studied may be examined on a computer monitor, printed or transferred to a CD.
