CT colonography for follow-up after surgery for colorectal cancer

Abstract

OBJECTIVE. The purpose of this article is to discuss the CT colonography (CTC) findings and the role of CTC for follow-up after curative surgery for colorectal cancer. CONCLUSION. Contrast-enhanced CTC can be effective for surveillance for colorectal cancer recurrence after curative surgery because it enables simultaneous evaluation of distant abdominal metastasis, pericolic recurrence, intraluminal recurrence, and metachronous lesions. The appearances of anastomotic recurrences at CTC overlap with those of more common inflammatory polyps and rare benign ulcers. © American Roentgen Ray Society.
