COMPUTED TOMOGRAPHY

Computed tomography (CT Scan) is a medical imaging technique that combines conventional x-ray imaging with computer technology to produce cross-sectional images of the human body. CT scans are capable of creating detailed views of the body’s soft tissues, including blood vessels, muscle tissue, and organs, providing valuable diagnostic information.

When you enter the exam room, you will see the CT scanner. The scanner is essentially a large circular machine with a table extending from an opening in the center. A highly trained CT technologist will help you get situated and comfortable on the table, explain the procedure, and answer any questions you may have. The technologist will monitor the exam from the adjacent control room. Throughout the exam, you will be able to communicate with the technologist using a two-way intercom.

As the exam begins, the table will gently slide into the scanner’s opening. Throughout the exam, you may hear the scanner rotating and feel the table move slightly to allow the scanner to capture the appropriate images. The technologist may ask that you hold your breath at certain points during the exam. This helps to minimize any blurring of images that can be caused by breathing or other motion.

In certain instances, patients may be given an intravenous injection to increase the contrast between different tissues.

While computed tomography is considered a safe examination, you will be exposed to a small amount of x-ray radiation. The Siemens CT scanner at our Maple Grove clinic reduces radiation exposure by up to 50% of the normal dose. In the vast majority of cases, the diagnostic benefit of a CT scan greatly outweighs the risk of radiation.

Depending on how many images are to be generated, a CT exam generally takes 30 to 45 minutes, although a very detailed study may take longer.

On the day of your appointment, we recommend that you avoid eating solid food or drinking any liquids for four (4) hours prior to your exam. In some cases, you will also be asked to drink a liquid contrast agent that will enhance the images captured by the CT scanner. Should your exam require any other special preparations, the healthcare provider scheduling your exam will give you instructions.

It is also recommended that you wear comfortable, loose fitting clothing to your appointment. In order to obtain the highest quality images, you may be asked to remove any items that could obstruct the scan such as belts or jewelry. If you prefer, you may change into a gown for your exam.

Following your exam, a radiologist specializing in CT will analyze and interpret the images from your exam and prepare a full report. This report will be sent directly to your physician who will share the results with you. To request a copy of the report, contact your physician’s office.
