Computed Tomography
CT stands for computed tomography. With CT, doctors can view the brain, sinuses, spinal column, bones, and internal organs. Helical CT offers several advantages over conventional CT, due to its ability to scan rapidly. The results are decreased radiation exposure, lower volume of contrast material, and less time for the procedure.
CT scans are generally performed to help diagnose the condition of organs, like the brain, liver, or kidneys, and bony structures, like the spine, pelvis, and hip. Other applications include three-dimensional CT before and/or after surgery, and vascular studies, known as CT angiography. Sometimes, contrast liquids are required to increase the visibility of certain organs. Depending on the exam, you may be given a contrast liquid by mouth and/or injection. For these exams, you will be asked to avoid normal eating or drinking for several hours prior to the exam. Because X rays are involved, it is important to inform the technologist if you are pregnant, or think you may be pregnant. The technologist remains in voice contact throughout the procedure, which takes about 10 to 20 minutes. In order to perform this examination satisfactorily, we ask that you follow the preparation instructions on the opposing panel. |
