CT Scan or Computer Axial Tomography
(CT or CAT) Imaging

We have added 6 new state-of-the-art scanners in 2010 with dose reduction features.  Radiation dose reduction is a priority for us at our facilities.

Computed Tomography, or CT, is an X-ray examination performed by a special scanner and computer. It provides more detailed images of the body’s tissues and vessels than conventional X-rays. The CT scanner takes pictures (images) of the body in multiple cross-sections or slices, similar to the slices in a loaf of bread, allowing visualization of images in three dimensions.


What are the advantages?

A CT scan is a painless, noninvasive method to view the health of tissues and vessels throughout the body. It diagnoses diseases and disorders of the digestive system, organs, urinary system, appendix, liver, spleen, pancreas and kidneys. It also locates or confirms the presence of tumors, identifies sources of pain, and diagnoses vascular disorders that can lead to stroke, heart attack or kidney failure. CT examinations aid in planning radiation treatments for tumors and for guiding biopsies and other minimally invasive procedures.

  • Unlike conventional X-rays, CT scanning provides very detailed images of many types of tissue including the lungs, bones and blood vessels
  • CT scanning can identify both normal and abnormal structures, making it a useful tool to guide radiotherapy, needle biopsies and other minimally invasive procedures.
  • CT scanning is painless, noninvasive and accurate.
  • CT Angiography can be used to examine blood vessels in many key areas of the body including the brain, kidneys, pelvis and the pulmonary arteries.

Common uses of CT

  • Evaluate coronary artery disease
  • Diagnose vascular disorders
  • Detect abscesses and infections
  • Identify strokes and bleeding in the head
  • Assist in needle-guided procedures
  • Detect presence of tumors
  • Evaluate bone fractures
  • Identify diseases and disorders of the digestive system and pulmonary system 

The Procedure

The technologist begins by positioning the patient on the CT examination table.  A nurse or technologist will insert an intravaneous (IV) line into a small vein in your hand or arm.  To make a clearer picture of certain parts of the body, a small dose of contrast material (X-ray dye) may be injected through the IV.  The entire exam usually takes less than one hour.

Radiation dose reduction is a priority for us at our facilities.  We added 6 new scanners in 2010 with dose reduction features.
