Operating instructions

CT Colonography

We recommend using a tube voltage of at least 120 kV.

A comprehensive study consists of four sections:

Preparation, examination in supine & prone positioning

and post processing.

• Patient preparation

In the case of CT Colonography, adequate prepa-

ration in bowel cleansing must be done prior to the

CT examination.

Important for good results in a CT Colonography

examination is the optimal preparation of the

patient.

The patient has to start with a diet and bowel

cleaning two days prior to the examination like for

a conventional Colonoscopy.

• Patient examination

The bowels can be delineated with air. Or, if desired,

with carbon dioxide, water or iodine/barium suspen-

sion.

Have patient inflate colon with air to maximum

tolerance.

To decrease colon spasm, e. g. Buscopan

™

Glucagon

™

can be given IV.

Usually a prone and supine examination are done

to differentiate between polyps and fecal matter

within the colon.

• Postprocessing
