Computer Tomography (CT)

A Computer Tomography scan (CT) is an imaging test used to take pictures of parts of the body to create detailed images of internal bones, blood vessels and organs.

• How to Prepare
  Avoid wearing jewelry or clothing with metal on it, especially if that area is being scanned. In some instances, your provider may order an intravenous (IV) contrast dye injection or oral contrast liquid to drink. This will require you to refrain from eating or drinking three hours prior. Tests using oral constrasts take longer, lasting approximately 1 ½ hours.  Please notify an imaging technologist if there’s a chance you could be pregnant.
• What to Expect
  During the scan, you will lie flat on an imaging table that moves through a doughnut-shaped tube. If contrast fluid is required, you may feel a warm sensation throughout your body as the fluid travels. Scans typically last 10-30 minutes.
• Getting Your Results
  A radiologist will interpret the images, formulate a report and send the results to your provider. Your provider will contact you to discuss your results.

Lung Cancer Screenings (CT)

Sleepy Eye Medical Center offers lung cancer screening counseling and shared decision-making visits for smokers. After a complete assessment with your provider, you may qualify for annual lung cancer screenings using low dose computed tomography (LDCT).

Lung cancer screening is an additional preventative service benefit under the Medicare program offered to smokers who meet a certain set of criteria. Eligible patients include those who are between the ages of 50 and 80 and have no signs or symptoms of lung cancer. They must have a history of smoking at least one pack a day for 20 years and either still smoke or quit smoking within the last 15 years. A written order from a health care provider is required for lung cancer screening at Sleepy Eye Medical Center.

Bone Densitometry (DXA)

Bone density scanning is an enhanced form of Dual-energy X-ray Absorptiometry (DXA) that is used to measure bone loss. Bone density scans safely, accurately and painlessly measure bone density.

The chance of bone fractures and risk of developing osteoporosis increase as a person ages. A DXA scan can help detect bone conditions early and prevent them from getting worse.

• How to Prepare
  Refrain from taking calcium supplements 24 hours prior to your exam. If you’ve recently had an exam that required a contrast solution, it is recommended to wait one week before having a DXA scan.
  Please notify an imaging technologist if there’s a chance you could be pregnant.

• What to Expect
  During the exam, you will lay on a padded table while a mechanical arm passes over two or more areas of the body, typically the hips and spine. The procedure takes approximately 20 minutes to complete.
• Getting Your Results
  A radiologist will read and analyze the images, formulate a report and send the results to your provider. Your provider will mail you a letter containing your results.

Magnetic Resonance Imaging (MRI) – mobile truck

Magnetic resonance imaging (MRI) uses a magnetic field, radio waves and computer to take detailed pictures of the spine, joints and organs that cannot be seen with other imaging devices.

• How to Prepare
  Dress comfortable and avoid wearing clothing or jewelry that contain metal. You will not be able to have an MRI if you have a pacemaker.  If you have questions or a fear of being enclosed in small or narrow spaces (claustrophobia), share these concerns with your provider prior to your scan.
