What is a CT study?
(Computerized Axial Tomography)
16 slice technology

Computerized tomography (sometimes called CAT scan) uses special x-ray equipment to collect image data from every angle around the body. A computer reconstructs the data to show a cross-sectional image of body tissue and organs.

CT imaging is better than conventional x-ray because CT does not superimpose anatomical parts. The better clarity and contrast CT provides is useful in demonstrating pathology for an accurate diagnosis.

Some CT studies will require you to drink a flavored liquid before your exam and receive an injection of contrast material. Contrast helps the radiologist visualize certain organs within your body.

You will lie on a padded table with your arms over your head for most of the 10 to 15 minute study. The table moves slowly through the gantry during the scan. You may experience a warm sensation when the contrast is injected. This is normal. The technologist can see and hear you at all times. You will hear low, whirring sounds of a motor spinning the x-ray tube around you.

Our CT allows for

• Better resolution/detail
• Retro reconstruction
• Multiplanar reconstruction
• Faster scanning
• Shorter breath holds for the patient
• Less IV contrast needed
• AW workstation for 3D reconstruction
• Patient report options include:  Internet based PACS provides all images-on-line-all the time, CD, Film

Preparation

• Wear comfortable, loose-fitting clothing, avoiding zippers, or snaps (on bulleted items, a period should not be placed at the end of the item).

• You may be asked to remove hairpins, jewelry, eyeglasses, hearing aids, and any removable dental work.

• You also may be asked to refrain from eating or drinking before the exam.
