Virtual colonoscopy (VC) offers a safe and effective method for colon evaluation, especially when other techniques fail. This review covers state-of-the-art VC techniques, cleansing, distension agents, and adjunctive medications.

Area of Science:

  • Medical Imaging
  • Gastroenterology

Background:

  • Virtual colonoscopy (VC) is increasingly important for colon evaluation.
  • It serves as a safer alternative or a last resort when other methods fail.

Purpose of the Study:

  • To review the current state-of-the-art virtual colonoscopy technique.
  • To present results from recent performance trials.
  • To discuss practical aspects of VC procedures.

Main Methods:

  • Review of current virtual colonoscopy techniques.
  • Analysis of performance trial data.
  • Discussion of colonic cleansing regimens, distending agents (room air, carbon dioxide), and antispasmodic drugs.

Main Results:

  • Virtual colonoscopy is a valuable tool for colon visualization.

  • Specific cleansing regimens and distension agents impact efficacy.
  • Antispasmodic drugs play a role in administration.

    • Conclusions:

    • Virtual colonoscopy is an established and effective method for colonic evaluation.
    • Optimizing technique, cleansing, and agent selection enhances performance.
    • This review provides practical guidance for clinicians.
