Computed Tomography (CT)

What Does CT Mean?

CT is an abbreviation for Computed Tomography

How Does CT Work?

Computed Tomography (CT) images are formed by combining the principles of x-ray with advanced computer technology. The images produced are cross-sectional patterned, much like a slice of bread. By taking a series of images, a CT scan can create a multi-dimensional view of the body, allowing physicians to provide an accurate diagnosis of medical conditions. The CT scanner at Western Neurological is a Philips 16 Slice Secura scanner that uses a significantly lower dose of radiation than other scanners. This scanner is a rapid, helical scanner that is capable of performing a wide range of diagnostic tests. CT imaging is more detailed than ordinary x-ray and it has the unique ability to demonstrate a combination of soft tissue, bone, and blood vessels.

Why Would My Doctor Order a CT?

CT allows physicians to see images of your internal organs and structures in great detail from many angles. This gives them information more quickly, and in many cases more economically, than in past testing and exploratory procedures. CT is ideal for but not limited to:

  • Diagnosing problems with the lungs, heart, and esophagus
  • Diagnosing problems with the abdomen and pelvis
  • Diagnosing problems with the urinary tract, kidneys, and bladder
  • Evaluating blood vessels
  • Evaluating problems in the brain, spine, and extremities

Will a CT Scan Hurt?

No. Since CT is “non-invasive,” the exam is painless. However, your doctor may utilize a contrast agent to better visualize a part of your body. In this case, you many be asked to drink an oral contrast or use an intravenous contrast.

What About Radiation?

WNA is accredited by the American College of Radiology which sets standards for radiation exposure. All CT Imaging is performed by a licensed technologist under the direct supervision of a radiologist. Every CT scan we perform is optimized to minimize radiation (x-ray) exposure to the patient.
