polyps or take tissue samples for a definitive diagnosis.
Furthermore, virtual colonoscopy may be less sensitive in detecting very small polyps, which could potentially be precancerous lesions, and it cannot assess areas outside the colon that are accessible during conventional colonoscopy.
Because of these factors, virtual colonoscopy can sometimes lead to a two-step process, requiring patients to undergo both imaging procedures and invasive interventions, which can delay treatment.
- Accuracy and recognition rate
Virtual colonoscopy is generally effective in detecting larger polyps and colorectal cancer. Its accuracy is comparable to that
