Commonly referred to as a "CT Scan,"
computed tomography uses X-rays to create highly detailed images
of internal organs. Since CT scanners are capable of rotating the
X-ray device, they can image detailed cross sections, called "slices,"
of areas of the body. Unlike images from conventional X-rays, CT
shows details of all tissues from organs, bones, blood vessels,
etc.
CT is used frequently to image the abdomen, body,
head, or spine. Your physician may order a CT scan to screen for
a variety of conditions, including heart disease, sinus problems,
certain types of cancer or tumors, or disorders of internal organs.
Preparation:
- No solid food for four hours prior to scan.
This restriction includes foods that are normally required with
certain medications.
- No caffeine for 12 hours prior to the scan.
- Clear, non-carbonated liquids, such as
Jell-O, broth, or apple juice can be consumed as desired, up to
one hour before the scan.
- If you are diabetic and
are taking the medications containing Metformin, you must be off
this medication for 48 hours after undergoing
the CT study.
