CT (Computerized Axial Tomography) Scans

CT scans are images taken with X-rays and a specialized computer. The scans provide cross-sectional "slices" of major body systems. High-resolution scans of small, intricate body structures are performed routinely.

CT scanning is the preferred technology to diagnose many conditions, including stroke, brain injury, chest and abdominal pain, and the diagnosis of certain cancers. Lake Hospital System's 16-slice CT scanners at LakeWest Hospital, LakeEast Hospital and the Mentor Medical Campus are faster than the traditional scanner and enable us to reconstruct images in a 3-D format, which allows for accurate diagnosing of your condition. In fact, LakeWest Hospital is the first hospital in Lake County to acquire a 64-slice CT scanner, which allows us to provide advanced coronary artery disease detection, too.

CT scans are available at LakeEast Hospital, LakeWest Hospital, and Mentor Medical Campus.

What to Expect

During a CT scan, you will lie on a table. The table will move slowly into a large doughnut-shaped scanner. You will be asked to lie still for a short period for each "slice" scanned and you may be asked to hold your breath at times. You may receive an IV contrast dye and may experience a warm sensation and a metallic taste in your mouth because of the injection. These sensations usually disappear in a short time. For an abdominal scan,  you may be asked to drink Barium before the exam. The scan causes no pain and the technologist can see, hear and speak with you throughout the exam.

A radiologist will interpret your exam and a report will be sent to your physician, who will discuss the results with you.

Preparing for Your CT Scan

If you have had an allergic reaction to contrast dye, please let your physician know. It may be necessary to take medication for several days prior to your exam to prevent an allergic reaction.

• Do not eat or drink for four hours before the exam.
• Take your usual medications with a small amount of water unless directed otherwise.
• Wear loose, comfortable clothing.
• Inform your physician or x-ray technologist if you are or may be pregnant.
• Please register 15 minutes before your scheduled appointment.
• Please bring a complete list of your medications, vitamins and supplements to your appointment.
• Please bring the physician order to your appointment.

Scheduling an Appointment

CT scan is performed by appointment only. You can schedule an appointment by calling Lake Hospital System's Centralized Scheduling Department at 1-866-652-5253.
