What is a CT Scan? 

A Computed Tomography (CT) scan is a painless medical test that helps physicians diagnose and treat medical conditions. CT is an X-ray technique that produces cross sectional views of the area being studied. A computer puts these thin section X-rays together to create detailed pictures of the inside of the body. CT imaging of the internal organs, bone, blood vessels and soft tissue can provide greater clarity than conventional x-ray exams. Physicians use this innovative technology to help diagnose disease and life-threatening illnesses, including cardiovascular disease, stroke and cancer. 

ACR CT Accreditation -The CT Departments at Silver Cross Hospital and Homer Glen Imaging received a 3-year accreditation by the American College of Radiology (ACR). 

How is the CT performed?

Patients are positioned on a moveable exam table. The exam table will then be moved into the CT machine. The CT technologist will perform the test in an adjacent room while watching the patient through a window. The patient and technologist will be in communication throughout the exam. 

Depending on the physicians order, intravenous and/or oral contrast might be requested. Oral contrast instructions will be provided during scheduling and can be accessed by clicking on the above link. If intravenous contrast is requested, your blood will be tested for kidney function prior to the injection. Intravenous contrast is given into a vein in the hand or arm. 

If you had a prior reaction to contrast or have any concerns about a possible reaction, please contact your physician before your exam or speak with the CT Technologist prior to your appointment date.  

If you are on Metformin containing medications, notify your CT Technologist.    

Preparing for Your CT Scan 

  • You will be asked to arrive 15 minutes prior to your appointment to register for your exam. A typical procedure takes 10 to 15 minutes depending on the information required by your physician.  Oral contrast studies may take up to 2 hours for the contrast to pass through your gastrointestinal tract. 

  • Patients should wear comfortable clothes that are easy to change as they may be asked to wear a gown for their procedure. 

  • You will be asked to remove metal items that may interfere with the CT exam such as jewelry, eyeglasses, keys, phones and other metal objects. 

  • Results are normally available to your physician in 24-48 hours.
