More than 30% of patients with Crohn's disease (CD) develop fibrotic strictures in the bowel as the disease progresses. Excessive deposition of extracellular matrix components in the submucosa and smooth muscle hypertrophy or hyperplasia are the main features of fibrosis in CD. Cross‐sectional imaging technology provides a wealth of information on the anatomy, histological composition, and physiological function of the bowel, allowing for a non‐invasive and complete evaluation of associated abnormalities. This review summarizes recent advances in and the potential technologies of cross‐sectional imaging for assessing intestinal fibrosis in CD, including ultrasound imaging, computed tomography, and magnetic resonance imaging.

用于评估克罗恩病肠道纤维化的横截面成像。

随着疾病的进展，超过30％的克罗恩病（CD）患者在肠道中出现纤维化狭窄。CD纤维化的主要特征是粘膜下层细胞外基质成分过多沉积和平滑肌肥大或增生。横断面成像技术可提供有关肠的解剖结构，组织学组成和生理功能的大量信息，从而可以对相关异常进行无创且完整的评估。这篇综述总结了横截面成像技术在评估CD肠道纤维化方面的最新进展和潜在技术，包括超声成像，计算机断层扫描和磁共振成像。
