The value of multi-modes of ultrasound in evaluating segmental mucosal healing in patients with Crohn's disease.

Background: Mucosal healing, the result of endoscopic remission, is associated with prolonged clinical remission and delayed deterioration of Crohn's disease, which is significant and accompanied by reduced hospitalizations and surgeries. Currently, the relationship between ultrasonic parameters and mucosal healing remains controversial. To establish an ultrasonic regression model to evaluate mucosal healing, we conducted this preliminary study using multiple parameters from B-mode ultrasonography, colour Doppler flow imaging and shear wave elastography systematically.

Using shear wave elasticity in normal terminal ileum of a healthy southwest Chinese population: a pilot study of reference elasticity ranges.

Background: Elastography has not been widely applied to the gastrointestinal tract. The bowel wall's normal elasticity values are still unknown and are necessary for studies of gastrointestinal diseases. This study explores the feasibility of using shear wave elastography (SWE) to measure the terminal ileum wall stiffness in healthy subjects and establish the corresponding normal ranges of elasticity values.

[The Diagnostic Value of Double Contrast Enhanced Ultrasound in Colorectal Neoplasms].

Objectives: To determine the value of double contrast enhanced ultrasound (DCEUS) in detecting colorectal neoplasms.

Methods: The conventional abdominal ultrasound and DCEUS (hydrocolonal ultrasound+intravenous contrast-enhanced ultrasonography) were performed in 77 patients with 79 colorectal tumors. The clinical, ultrasonic and pathological data of the patients were reviewed.
