How is the CT Pelvic Scan Procedure Performed?
In a CT pelvic scan, several x-ray beams pass through the pelvic at various
angles. Special sensors measure the amount of radiation absorbed by different
tissues within the pelvis.
In order to undergo a CT pelvis scan, the patient’s general physician must
write a letter of referral stating why he or she believes a CT pelvic scan is
necessary. A CT pelvic scan will take place in either a hospital or in an outpatient
radiology center.
During a CT pelvic scan, the patient lies still on a table. The table is rolled
into the center of the CT scanner. The CT scanner revolves around the patient
and emits and records x-ray beams. The different areas of the pelvic absorb
different amounts of x-ray. A special computer program then forms graphical
cross-sections, or “tomograms,” based on these x-ray absorption differences.
Once the patient enters the scanner, the technologist may turn on special lights
to ensure the patient is positioned properly for the CT pelvic scan. Though
the technologist will not actually be in the room with the patient, an intercom
within the scanner allows the patient and technologist to communicate throughout
the procedure.
The duration of the CT pelvic scan depends on the number of images needed to
get the information the doctor requires. At the conclusion of the CT pelvis
scan, the technologist will look over the images to ensure sufficient images
have been created to provide the radiologist with the necessary information.
If more images are necessary, the technologist will ask the patient to stay
for further scanning.
