Summary:
CT colonography (CTC) is a CT examination of the colon, in which the images
are interpreted on a workstation using two-dimensional (2D) and
three-dimensional (3D) techniques.
Technological progress has contributed in the improvement of various factors of
the examination, such as the reduction in processing time of high definition
images, the reduction of the radiation dose and the use of new presentation
methods which result in an improved evaluation of the examination.
The clinical role of the CTC has been investigated and evaluated in many
clinical studies.
Current CTC indications include the incomplete conventional colonoscopy (CC),
the evaluation of patients who are unfit for CC, tumor mapping prior to
laparoscopic surgery for colorectal cancer (CRC) and the stoma evaluation.
CTC presents the principal advantage of allowing the evaluation not only of the
entire colon, but also of the colon wall and the pericolonic fat.
The most important disadvantages include the inability to carry out a biopsy
and the exposure of the patient to radiation.
Due to the high sensitivity and specificity of the CTC for the identification
of colorectal cancer and polypoid lesions, the American Cancer Society includes
CTC among the five screening methods for colorectal cancer.
CTC has proved to be a reliable, minimally invasive, safe and well tolerated
imaging method of the colon.
