Real time strain elastography accurately dfferentiates between inflammatory and fibrotic strictures in Crohn's disease

Purpose: There are no reliable, non-invasive imaging techniques that can differentiate between inflammation and fibrosis in Crohn Disease (CD). Strain Elastography (SE) via transcutaneous ultrasound is a non-invasive technique for assessing strictures. The purpose of this study is to evaluate the accuracy of real-time SE for the characterisation of CD strictures in comparison to histopathological assessment of surgical resection specimens. Material and methods: Preoperative ultrasound with SE was performed in 28 consecutive patients with known strictures of the terminal ileum undergoing elective resection. Longi…
