CT (CAT Scan)

  • Needle Placement
  • Drain Insertion
  • Biopsy
  • Thoracentesis
  • Paracentesis

Your CT procedure is performed in the CT area of the Radiology Department by a trained and accredited imaging technologist.

The CT scanner is a donut-shaped tube with a “camera” inside the tube that rotates around you during the exam to take the pictures.

You will need to go without food or liquids for at least 4 hours before the exam.

Lab tests are required to assure that your procedure is safe for you. Our Radiologist may talk with your doctor about the lab results to make sure the procedure is safe for you. Sedation medication will be given to you through a standard IV. You will need to sign the Moderate Sedation Consent form before your nurse starts your IV.

Once you arrive in the CT area, our Radiology nurse will give you the sedation medication through your IV.

The technologist and nurse will position you on the exam table to begin the exam. The exam table that you will lie on will move you in and out of the tube to image the targeted body area. It is important that you lie very still and keep your eyes closed during the exam.

The exam can take anywhere from 30 minutes to 2 hours.

Your doctor is able to see the pictures once your exam is completed. A report about the images is sent to your doctor within 12 hours.

IV Contrast
The contrast is given through an IV. Your nurse will start the IV, using a 20 gauge saline lock.

Once you arrive in the CT area, your technologist will give you the contrast through your IV.

Oral Contrast
The Radiologist and your doctor may feel that oral contrast is better for you. About an hour before your exam, your technologist will bring containers of the contrast blended with a lemonade mix for you to drink.

Exam
