Having a CT

If you have been told you will be having a CT at Pinnacle Hospital, the following information will provide you with basic information about the procedure, how to prepare, and what to expect.

What is a CT?
CT of computed tomography uses powerful X-ray technology, often utilizing an iodine dye (contrast material) to create the best 3-D image. It provides physicians with the highest level of contrast resolution to create the most vivid images of internal organs. CT procedures are commonly used to detect tumors, blockages in blood vessels, and review actual function of organs by taking a series of images or “slices” that can be viewed in succession, similar to a video. The patient is placed on a table, which is passed through a large ring-shaped device.

How to prepare for a CT
Prior to your CT procedure, you will receive general instructions about eating and drinking restrictions. It is advised that you remove all jewelry and accessories before arriving at Pinnacle. Prior to your procedure you will need to remove any hearing aids and removable dental work.

Before your procedure, an iodine or contrast agent may be administered. This dye is either administered through a vein or swallowed. Please advise the technician if you have ever had an adverse reaction to an iodine or contrast agent.

Please advise the imaging technician of any of the following:

• You are pregnant
• You are breastfeeding (do not breast feed for two days after the procedure)
• You are allergic to iodine dye
• You have kidney problems - the contrast can damage the kidneys
• You have a history of thyroid problems
• You have diabetes
• You have a heart condition such as heart failure
• You have had a barium enema within four days of the CT

You will remove most articles of clothing, depending on the procedure, and wear a hospital gown during the procedure.

During the CT
You will lie on a table and the CT ring will surround or move around you. It is important that you lie as still as possible to attain the most accurate images. A technician in an adjacent room will conduct the procedure and speak to you throughout the process. Some patients who are uncomfortable in small spaces may be given medication prior to the procedure. The imaging session should last between 30 and 60 minutes. A waiting room is located near the imaging center for family or visitors.

After the CT
After your CT, you will get dressed and be able to leave on your own. If you took a sedative before the procedure, an adult will be required to drive you home.
