Course of Examination
The virtual colonoscopy is performed using a modern computerized tomography
scanner (CT). For this procedure, the lowest possible dose of radiation
is used. This dose is equivalent to the half of the natural radiation
that you are exposed to during the course of one year in Germany (0,8-1,6
mSv). The only radiation free alternative would be the magnetic resonance
imaging (MRI). However, the MRI's resolution does not yet provide a
sufficient image resolution of polyps.
If polyps are detected during the virtual colonoscopy - which is the
case in only 20% of all examinations - they can be marked exactly and
removed more easily. In this case the virtual colonoscopy would immediately
be followed by a conventional colonoscopy.
The following pages describe the preparations and procedure of the virtual colonoscopy.
