Computed Tomography Scans

CT ScanCT Scanner

A CT (Computed Tomography) scan is an X-ray examination, which is performed by a special scanner that can look at any part of the body in cross sections. The X-ray tube rotates around the area being examined taking X-rays of the body in multiple slices. The data is then fed back into a computer that combines all the information collected and produces images (pictures) that are reported on by our Radiologist to your doctor.

Madelia Community Hospital & Clinic has a Siemens SOMATOM Perspective 64-slice Scanner. This CT Scanner offers an impressive spectrum of dose reduction features, achieving up to a 60% dose reduction for a wide range of applications while providing excellent image quality.

What should I expect  BEFORE my CT scan?


If you are diabetic and take diabetic medications, you should take your prescribed dose as normal the day of the exam, but discontinue the next doses for 48 hours after the CT scan.

Food and Drink

For most CT scans there are no restrictions on what you may eat or drink. For the exceptions, instructions will be given at the time your appointment is scheduled.

You may be asked to arrive 45 minutes to an hour early and given an oral contrast agent to drink before the procedure. This helps to enhance pictures of the stomach, small intestines and bowel. 


Wear comfortable clothing, preferably clothes with no metal (zippers, eyelets, buttons or snaps) such as a sweat suit. You may be asked to change into a gown upon arrival. Glasses, piercings, removable teeth, and anything else that contains metal should be removed so it does not interfere with the radiographic detail.  TOP

What will I experience DURING my CT scan?

Contrast Agents

Contrast agents are often administered prior to CT scans for more detailed test results. The method of administering the agents varies depending on the area of the body that is being scanned: 

  • You may have an IV started if you are scheduled to receive intravenous contrast material. This contrast material may make you have a warm, flushed sensation during the injection and a metallic taste in your mouth that lasts for a few minutes.
  • If you are receiving contrast material orally, you may find the taste mildly unpleasant; however, most patients can easily tolerate it. Expect to experience a sense of abdominal fullness.

The Scan

Your technologist will have you lie on the scanning table, sometimes using straps and foam pillows to position your body. The radiographer is required to leave the room during the exam, but can hear you and talk to you through a microphone at all times. Depending on the scan, the radiographer may have you hold your breath for a brief time to ensure minimal movement under CT.

The scan table will move through the scanner as needed to obtain the images requested by your doctor. It is very important that you lie very still. Movement may make your pictures look blurry. The equipment makes noises such as clicks and buzzes while taking the images. Please don’t be alarmed – this is normal. Depending on the type of CT scan your doctor ordered, it may take anywhere from a few minutes to half an hour or more to complete. TOP

What should I expect AFTER my CT scan?

After a CT exam, you can return to your normal activities. If you received contrast material, you may be given special instructions.

Drinks lots of liquids for 24 hours after the scan to help flush the contrast agents out of your body.  TOP


The scan usually takes 5 - 20 minutes and afterwards the images obtained by your CT scan are studied by the Radiologist who prepares a report on the findings, which are sent directly to your doctor. TOP
