Endometriosis also reacts to hormonal signals of the monthly menstrual cycle by building up tissue, breaking it, and eliminating it through the menstrual period. In this article, we will discuss what is computed axial tomograghy (CT scanning or CAT) in endometriosis ?

I. Definition
CT scanning is a X ray medical instrument that generates a three dimensional image of an object from a large series of two-dimensional X ray that rotates around a single axis.

CT scanning is a safe, painless and little risk to patient. As you lie on your back, a X ray tube rotates around your body in a circle and takes multiple images and transfers these images of data the reformation in various planes or even as volumetric (3D) representations of structures. CT scanning is valuable to look at soft tissues, bone, blood vessels and provide information about size or shape of any abdominal abnormality such as endometrial adhesion, implants, tumors, fibroids, etc.

III. Risk
Some researchers say there are no risk because of minimum exposure for radiation, but the American Cancer Society's director of screening estimates that 2 percent of future cancers may be due to CT scanning.
