The diagnostic accuracy of abdominal ultrasonography in Crohn's disease has been assessed in a prospective, randomized, simple-blind controlled study. A group of 181 out-patients (89 with accertained Crohn's disease and 92 controls) was studied. Considering "target sign" and/or "probable signs" of Crohn's disease, ultrasonographic sensitivity in diagnosing Crohn's disease was 84% and specificity 83%. Abdominal ultrasonography is indicated in the differential diagnosis of inflammatory bowel diseases, in the screening and follow-up of patients with Crohn's disease and in cases with contraindications to X-Ray examinations.
一项前瞻性、随机、单盲对照研究评估了腹部超声检查对克罗恩病的诊断准确性。研究了一组181名门诊患者（89名确诊为克罗恩病，92名对照）。考虑到克罗恩病的“靶征”和/或“可能的征象”，超声检查诊断克罗恩病的敏感性为84%，特异性为83%。腹部超声检查适用于炎症性肠病的鉴别诊断、克罗恩病患者的筛查和随访以及有X线检查禁忌证的病例。
