Bowel Wall Thickness Cutoff Value for Assessing Inflammatory Bowel Disease Activity Using Intestinal Ultrasonography in Children

Although IUS is an excellent tool for detecting moderate/severe bowel inflammation, this method showed limited accuracy in children <6 years old. The adult BWT cutoff missed over 30% of bowel inflammation in children. BWT cutoff of 0.27-0.30 cm in boys and 0.23-0.25 cm in girls and/or children <40 kg indicated active gut inflammation.
