Crohn’s disease (CD) is one of inflammatory bowel diseases, characterized by lifelong relapsing-remitting clinical course. The choice of treatment protocols is based on the comprehensive evaluation of the disease. And the treatment protocols should be adjusted according to the response to the treatment and the drug tolerance. Repeated assessment of the activity of intestinal inflammation is very necessary. Each of endoscopy, Crohn’s Disease Activity Index, CT, magnetic resonance enterography, and ultrasonography (US) has its own disadvantages. US is widely used in clinical practice because of its no radiation, convenience, low cost, and high degree of patient tolerance. The two-dimensional ultrasound, Doppler ultrasound, elastosonography, and contrast-enhanced ultrasonography each provides some effective parameters for evaluation of CD activity. Some parameters are of high value, such as bowl wall thichness, bowl wall stratification, color Doppler signal, strain ratio, and relative enhancement, etc. The values of some parameters are disputed, such as the blood flow of superior mesenteric artery, time to peak, etc. Some studies combine several ultrasound parameters and calculate their respective weights to obtain an ultrasound scoring method. US, as a valid tool to evaluate CD activity, provides valuable help in solving clinical problems such as evaluation of therapeutic effect, mucosal healing, and postoperative recurrence.
