Interpretive Pitfalls at CTC

Potential pitfalls related to technique

  • Retained solid fecal material

  • Retained luminal fluid

  • Inadequate luminal distention

  • Imaging artifacts and distortion

  • Low-dose CT technique

  • Contrast coating of polyps

  • 2D-only polyp detection

  • Polyp measurement

Potential pitfalls related to anatomy

  • Thickened colonic folds

  • Diverticular disease

  • Flat lesions

  • Submucosal and extrinsic lesions

  • Anorectal Pitfalls

  • Ileocecal valve pitfalls

  • Appendiceal pitfalls
