Imaging in the diagnosis of small bowel diseases / 中华胃肠外科杂志

ABSTRACT

There are still many difficulties in the diagnosis of small bowel diseases. Until recently, diagnosis of small bowel diseases relies primarily on imaging techniques. The traditional gastrointestinal barium meal examination and endoscopy can observe the changing of mucous membrane, but can not demonstrate the intestinal wall and the extraluminal structure. With the development and modification of CT and MR software and hardware, CT enterography (CTE) and MR enterography (MRE) are being increasingly usded in clinical practice, facilitating discrimination of mucous membrane, wall, lumen and extraluminal structure. Dynamic contrast scanning can reflect the blood supply of intestinal lesions, and CTA and MRA can reveal the vascularity and abnormality. Comprehensive analysis of imaging can provide overall and objective information and improve diagnostic accuracy of small bowel diseases. Besides, imaging features can be used as criteria in assessing the activity of Crohn's disease, which provides effective method of treatment selection and efficacy evaluation.
