Computerized Tomography CT Scan

Computerized tomography (CT) combines the principles of x-ray with the use of a high-speed computer to create pictures of a cross-section of a part of the body. This painless, non-invasive procedure provides images that are invaluable in the diagnosis of a wide variety of conditions.

In a matter of seconds, our new light-speed, multi-slice CT scanner creates highly detailed images that used to take an hour. The scanner then takes these individual images, or "slices," and reconstructs them into three-dimensional, rotating images of the body part being examined.

Because it is able to detect some conditions that x-rays cannot, a CT scan can often replace exploratory surgery and other, more invasive diagnostic procedures. In general, a CT scan shows the outlines of soft tissue and bone. CT technology can be used to:

  • Show abnormalities in the brain and the eye, including tumors, blood clots and enlarged ventricles.
  • Determine if a growth is solid or fluid-filled, and if an organ's size and shape are normal. This is important in diagnosing conditions such as enlarged lymph nodes, pancreatic disease, back problems and lung cancer.
  • Perform guided biopsies of liver, kidneys and bones by identifying the location and type of tumor.

Using a CT scanner we can put a needle into a tumor and then burn it by heating up the end of the needle. The scanner provides guidance for the person directing the needle into the tumor. In addition to diagnostic uses, CT technology can be used to shrink and kill certain types of cancerous tumors. Called radio frequency ablation, this procedure is less invasive than surgery and is typically used to treat inoperable tumors.
