Computed Tomography or CT creates highly detailed images of the inside of the body. Unlike a traditional x-ray which shows subtle outlines of the organs, CT is able to show the organ in detail. The images are created by an x-ray unit that rotates around the patient. In some cases a contrast material is used to enhance the images of the inside of the body. These images can then be interpreted by a radiologist on a computer monitor. CT imaging provides excellent anatomic information.
