|Computed Tomography (CT)|
CT stands for Computed Tomography. CT gives detailed information by taking cross-sectional images throughout the body on a spiral scanner. CT scan, like conventional x-ray, uses radiation. Depending on the type of exam your physician orders, you may have to drink a flavored liquid before your exam(oral contrast) and/or receive an injection of contrast material. Contrast allows for better visualization of certain organs within the body. The CT equipment has a table that goes through a "doughnut". Exams take 5 minutes to 20 minutes.
The following is an explanation of a typical exam (exams may differ based on individual patients): You will be lying down on an examing table and a technologist will assist you into a comfortable position for your exam. A contrast medium may be injected at this point. If having a head CT, head may be cradled as the slightest motion may hinder image quality. You will be moved into the CT scanner. The technologist can hear and see you at all times. You may hear low "motorized" sounds. You will be moved out of the CT scanner. The technologist will assist you in getting off the table. Your exams will be interpreted by the radiologist and your physician will receive the results.
