Computerized Tomography (CT)


A CT scan, sometimes referred to as a “CAT” scan, is a diagnostic, non-invasive procedure using X-rays and computers to produce detailed, cross-sectional images of internal structures of the body's tissues and organs.

The computer reconstructs these “slices” to produce multi-planar and 3-D images. The result is a series of pictures with greater detail than traditional X-rays.

CT imaging is highly accurate and can show several types of tissue including lung, bone, soft tissue, and blood vessels.

A CT scan can be performed with or without the use of a “dye” Most CT scans are performed in less than 10 minutes without discomfort.
