Figure 1From: Doppler ultrasound findings correlate with tissue vascularity and inflammation in surgical pathology specimens from patients with small intestinal Crohn’s diseaseExamples of semiquantitative assessment of bowel wall vascularity using Doppler US according to Limberg score. (A) Grade 0 = no bowel wall thickening, no vascularization; (B) Grade 1 = bowel wall thickening without vascularization; (C) Grade 2 (hypo-flow) = bowel wall thickening with short stretches of vascularity as spots; (D) Grade 3 (hyper-flow) = bowel wall thickening with longer stretches of vascularity; (E) Grade 4 (hyper-flow) = bowel wall thickening with longer stretches of vascularity reaching the mesentery.Back to article page
