Answer

Imaging studies

  • A single-contrast upper GI radiologic series with small-bowel follow-through (SBFT) can be used to evaluate the small intestine, which cannot be reached during endoscopy

  • Magnetic resonance enterography (MRE) [2] and computed tomography enterography (CTE) are as sensitive and specific as SBFT for detection of small bowel inflammation and may be more accurate for detection of extraenteric complications, including fistulae and abscesses [3]

  • MRI is especially useful in the evaluation of pelvic and perianal disease

  • Abdominal ultrasonography (US) can be used to investigate intestinal disease and to rule out gallbladder and kidney stones
