Comparison of high-resolution ultrasound and MR-enterography in patients with inflammatory bowel disease

Table 5 Possible explanations for misdiagnosis of all evaluated features (wall affection, stenosis, abscess, fistula, lymph nodes and indirect inflammation signs) for ultrasound and magnetic resonance enterography for all 250 evaluated cases

	HR-US	MRE
Reduced imaging quality (obesity, breathing artifacts, residual bowel gas, etc.)	25	7
Region difficult to access (lesser pelvis)	72	N/A
Subtle findings	15	31

Magnetic resonance enterography (MRE) missed most of the diagnoses made by ultrasound (US) because of subtle US findings (n = 31), while the most common reason for a misdiagnosis based on the US report was an anatomical region difficult to assess (n = 72).
