摘要克罗恩病（CD）是一种慢性、复发性炎症性肠病，需要反复进行肠道评估。近年来，肠道超声（IUS）以其非辐射、非侵入性、耐受性好、成本低廉和易于重复等优点，在CD的诊疗过程中受到越来越广泛的应用。IUS的各项参数，例如肠壁厚度、肠壁分层、肠壁血流信号和爬行脂肪等，在CD诊疗中能提供大量关键信息。IUS不仅能准确诊断CD及其并发症，还能良好地评估CD疾病活动性和治疗反应，并且有效预测CD透壁缓解、病程、手术风险和术后复发。IUS在CD的诊断、评估和预测方面表现出良好的准确性。

abstractsCrohn's disease (CD), a chronic and recurrent inflammatory bowel disease, requires repeated intestinal evaluations. As a non-radioactive, non-invasive, well-tolerated, inexpensive and easily reproducible detection tool, intestinal ultrasound (IUS) has been more and more widely used in the diagnosis and treatment of CD in recent years. Various parameters of IUS, such as bowel wall thickness, bowel wall stratification, color doppler signals, and inflammatory mesenteric fat, provide a lot of critical information in the diagnosis and treatment of CD. IUS can not only accurately diagnose CD and its complications, but also well evaluate CD disease activity and treatment response, and effectively predict CD transmural remission, disease duration, surgical risk, and postoperative recurrence. IUS has demonstrated good accuracy in the diagnosis, evaluation and prediction of CD.
