CT Scan

What is a CT Scan?

A CT scan, also referred to as a CAT scan, is a diagnostic imaging test used to aid in diagnosis of many different medical conditions. CT provides detailed, cross-sectional images of internal organs, bones, soft tissues, and blood vessels. CT provides images with more detail than regular X-ray exams. At Spencer Imaging Center, we utilize equipment that produces the lowest radiation dose and shortest scan times possible to improve comfort.

What happens during the test?

Upon entry into the CT suite, the technologist will ask for a brief medical history. They will explain the exam to you in detail and answer any questions you may have. You will then be asked to lay down on the scanning table and given a cushion for your knees to increase comfort. If IV contrast is required for your exam, an IV will be placed at this time. Then the part of your body to be imaged will be positioned in the large doughnut-shaped ring called a gantry. If IV contrast is needed, it will be given mid scan. The IV contrast may make you feel warm and flushed and have a metallic taste in your mouth for a few seconds. You may be given specific breathing instructions and will be instructed to hold still. The CT is quiet, and scan times are often short. Plan for a 15-to-45-minute appointment.

How do I prepare for the test?

You may be given an oral or IV contrast agent as specified by your ordering provider. If you are receiving an oral contrast solution, you will be asked to drink over 90 minutes prior to being imaged. This time frame allows the X-ray dye to move through your digestive tract to aid in locating any abnormalities. If you are receiving IV contrast, you will be asked to fast for 4 hours prior to your exam and a kidney function lab draw may be required prior to arrival. For exams that do not require contrast agents, no preparation is required. Please inform the technologist if you are pregnant and if you’ve had any prior imaging so they can be obtained for comparison.

When can I expect the results?

A radiologist will review the images and we will send a report to your referring provider within 24 to 48 business hours. Your referring provider will review the report and contact you with the results.

After the test

You may return to normal activities following your exam. If you are given IV contrast, you will be asked to drink lots of fluids for the next few days. This will help the contrast pass naturally through your body.
