Virtual colonoscopy (VC) has acquired an important role in evaluation of the colon. In some situations it may be a safer method to visualize the colon effectively, or it may be the only available option when other techniques have failed. This article reviews state-of-the art VC technique and the results of current performance trials. It discusses the rationale for using various colonic cleansing regimens for VC. It also discusses the two distending agents for VC (room air and carbon dioxide) and presents practical tips for administration and the role of antispasmodic drugs.
