Small intestine contrast ultrasonography vs computed tomography enteroclysis for assessing ileal Crohn's disease

Figure 1 The figure shows images from the distal ileum from one patient with Crohn's disease of the distal and neo-terminal ileum undergoing ileo-colonic resection, as assessed by small intestine contrast ultrasonography and computed tomography-enteroclysis. A: Small intestine contrast ultrasonography (SICUS) showed a stenosis of the terminal ileum, with a thickened bowel wall, with lumen narrowing. The lumen diameter did not change after the ingestion of polyethylen glycole; B: Computed tomography-enteroclysis (CTE) showed findings comparable with SICUS, including a marked narrowing of the distal ileum, associated with an increased bowel wall thickness; C: SICUS showed a stricture of the neo-terminal ileum presenting as a thickened bowel wall, with lumen narrowing associated with pre-stenotic dilation; D: CTE showed findings comparable with SICUS, including a marked narrowing of the distal ileum, associated with an increased bowel wall thickness, but no bowel dilation).
