CT Preparation

CT Preparation

CT scanning allows your physician to see inside your body without the need to operate because it creates a high resolution, 3-D image of the body. The images produced are similar to what a surgeon would see when performing an operation. Because CT images are more detailed than the images produced by conventional X-Rays, there is greater accuracy and an ability to detect small abnormalities that might have otherwise gone undetected. It is fast, effective and the risks are low.

Brain or Chest

Any exam with contrast, nothing to eat or drink for 2-4 hours before exam.

Abdomen and/or Pelvis

Pick up Prep Kit from Elko Diagnostic Imaging or your doctor at least one day prior to exam. The barium contrast you have been given will taste better if refrigerated. Please be advised that the prep may cause mild to severe diarrhea. It is extremely important that you drink all of the barium, and at the specified times. We realize this is a lot to drink. However, the contrast is important for the best CT images.

You may have a light meal up to 4 hours prior to your exam.

You may take your medications up to the time of your exam with as little fluid as possible.
