Abstract
Background
Computed axial tomography (CT) colonography is the latest radiologic technique to
be used to image the large bowel. We studied its role as a diagnostic tool in colorectal
practice.
Methods
One hundred and three patients suspected of having colorectal pathology underwent
CT colonography.
Results
CT colonography suggested a diagnosis of colonic carcinoma in 18 patients, and 17
of these underwent surgery. A colorectal neoplasm was not found in only 1 patient
who had extrinsic colonic compression by an ovarian cyst. Twenty-one patients had
suspected colonic polyps on scanning. Subsequent endoscopy in 19 of these patients
confirmed the presence of polyps in only 10. CT colonography also revealed valuable
extracolonic pathology: 8 occult noncolonic neoplasms and 163 other incidental findings.
Conclusions
CT colonography has good patient compliance and is a useful diagnostic modality in
detecting colorectal neoplasms. Its main advantage over other such investigative tools
is its ability to detect extracolonic pathology.
