Abstract: Sixty patients with ulcerative colitis (UC),including 28 males and 32 females were enrolled in the study.Color Doppler ultrasonographic scans were performed and the disease activity was estimated base on the Sourtherland score index (DAI).On the sonography the colon with active inflammatory disease showed bowel wall thickening,alteration of layers structure or even discrimination and increased vascular signals.Using DAI as the gold standard,the sensitivity,specificity,positive predictive value,negative predictive value and accurate rate for ultrasonography in assessment of UC activity were 90.0％ (36/40),75.0％ ( 15/20),87.8％ (36/41),78.9％ (15/19),85.0％ (51/60),respectively.In conclusion,Color Doppler ultrasonography provides a convenient technique for assessment of bowel involvement and inflammatory activity in ulcerative colitis with high sensitivity and accuracy.
