Enterography

General Information

Computerized Tomography (CT), also known as "Cat Scan", is a diagnostic imaging tool that takes cross-sectional images of the body using x-rays.  CT assists Physicians in detecting disease, tumors, or infections and injuries to internal organs.  Additionally, Bones can be evaluated for fractures and other lesions.  CT provides excellent anatomic clarity and detail that is not available with traditional diagnostic imaging (plain x-rays).  This is critical when it comes to head and neck exams, gastrointestinal exams, urological exams and CT Angiography (CTA) exams.

What is CT Enterography?

CT Enterography is a new diagnostic tool in evaluating Small Bowel Disorders.  CT Enterography is highly sensitive and specific for Crohn’s disease, and it is increasingly being used to stage the small bowel.

CT Enterography combines a CT scan with large volumes of oral contrast to image the small bowel.  This can help you determine a diagnosis and potential therapies that may be used in treatment.

What are the benefits of CT Enterography?

Compared with traditional small bowel follow through examination, CT Enterography has several advantages:

  • It displays the entire thickness of the bowel wall
  • It allows examination of deep ileal loops in the pelvis without superimposition
  • It permits evaluation of the surrounding mesentery and perienteric fat

CT Enterography also allows assessment of solid organs and provides a global overview of the abdomen.

What will the patient experience?

Upon arrival, the patient will begin drinking oral contrast in timed intervals.  Once this is complete, they will lie on the exam table and be given contrast material through an IV.  There will be a brief breath hold (20-30 seconds) as the scan is performed and the images are acquired.

What is the prep for the procedure?

NPO four hours prior to the scheduled exam time.

How long will the test take?

The patient will check in 1 1/2 hours prior to the exam to register and begin the timed oral contrast.  The CT scan will take approximately 10-15 minutes.
