CT Colonography
We recommend using a tube voltage of at least 120 kV.
A comprehensive study consists of four sections:
Preparation, examination in supine & pronepositioning
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™or
Glucagon™can be given IV.
Usually a prone and supine examination are done
to differentiate between polyps and fecal matter
within the colon.
• Postprocessing
