Yes, CT colonoscopy can detect crohns related abnormalities though the test may have a few disadvantages over conventional colonoscopy such as visualisation not being as clear or inability to take biopsy samples. On the other hand, the procedure is much more comfortable than conventional colonoscopy at the patients end. With a clear CT colonoscopy and a positive sigmoidoscopy, the decision for a conventional colonoscopy/ conventional CT or directly initiating a management plan is best taken by the treating gastroenterologist based on the CT colonoscopy report. Though if the CT colonoscopy report is absolutely clear, chances that abnormalities are unlikely to be present. I would suggest discussing the situation and the suggested management plan in detail with your treating gastroenterologist.
Hope the information is helpful.
