小肠梗阻具有很高的发病率,早期准确诊断和全面病情评估是临床选择治疗方式的前提。多层螺旋CT(MSCT)在评价是否存在小肠梗阻、梗阻部位、严重程度及梗阻病因方面均具有很高的准确度,对继发性肠缺血也能提供有价值的影像学信息。本文对MSCT在小肠梗阻评价中的应用现状进行综述。 Small bowel obstruction has a high incidence, accurate early diagnosis and comprehensive assessment of the condition is the prerequisite for clinical choice of treatment. Multi-slice spiral CT (MSCT) has high accuracy in assessing the small bowel obstruction, the site of obstruction, the severity and the cause of obstruction, and can also provide valuable imaging information for secondary intestinal ischemia. This article reviews the status of MSCT in the evaluation of small bowel obstruction.
