CT combines the use of X-rays with the latest computer technology and is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments. CT is an ideal way to accurately view the size, shape and position of soft tissue structures such as the lungs, liver, kidneys and other internal organs. CT scanning is a painless procedure.
Patients are asked to lie still on a moving table as it inches its way through a doughnut-shaped “gantry”. Thin X-ray beams spiral around your body capturing slices that a computer reconstructs into a complete image. Imagine the body as a loaf of bread, looking at one end of the loaf. As you remove each slice of bread, you can see the entire surface of that slice from the crust to the center. The body is seen on CT scan slices in a similar fashion from the skin to the central part of the body being examined. When these levels are further “added” together, a three-dimensional picture of an organ or abnormal body structure can be obtained.
