What is a CT Scan? 
Computed Tomography scans use rotating x-ray beams to acquire cross- sectional images of the body. The scan is performed in a ring-shaped machine, usually taking less than a minute to perform. Modern scanners, with the aid of computer systems, can use the cross-sectional images to create 3D images of the internal organs. The images are then reviewed by a radiologist.

Our new 40 detector Somatom Sensation CT demonstrates leadership in innovative technology and clinical applications never before achieved. Somatom Sensation allows for maximal diagnostic detail at the fastest acquisition speed and the lowest possible radiation dose. Our computer-assisted reading tools also enable early detection, fast evaluation, and precise follow-up of disease with all information available at the scanner before the patient is off the table.

A CT scan provides a high resolution image of the body and is currently the preferred method for diagnosing many diseases and injuries. CT scans can also be used for pre-operative planning and to monitor recovery from illness. It is also an excellent method of assessing atherosclerotic disease. The images can be printed on x-ray film or burned to a compact disc to distribute to other physicians.

Many types of CT scans do not require patient preparation, but some require either an oral dose or an IV injection of contrast material (x-ray dye). Contrast provides improved definition of the internal organs and increases the sensitivity of the scan in terms of detecting some diseases.
