      목적: 크론씨 병 환자에서 CT 소장 조영술의 소견과 Crohn's Disease Activity Index (CDAI), C reactive protein (CRP) concentrations을 비교한 연구는 거의 없었다. 이 연구는 활동성 크론씨 병의 CT 소장 조영술 영상소견을 알아보고, 이와 CDAI, CRP의 연관성에 대해 평가하고자 하였다.
      대상과 방법: 2007년 3월에서 2011년 3월까지 본원에서 염증성 장 질환으로 내원한 환자 중 CRP와 내시경을 시행하고 14일 이내에 CT 소장 조영술을 시행한 환자를 대상으로 하였고, 환자군은 28 명 (남자 12명, 여자 16명)로 구성되었다. CDAI는 임상적 평가와 검사실 소견을 바탕으로 평가하였다. CT 소장 조영술은 90분동안 2L의 솔비톨 용액을 경구로 투여한 후 120mL의 조영제를 4mL/sec의 속도로 정맥주입 하여, 조영 후 40-75초에 시행하였다. 장벽의 조영 증강, 장벽비후의 두께, 과녁징후, 과혈관성, 주변부 지방층 침습의 다섯 가지 CT 소견을 평가하였다. 두 명의 영상의학과 전문의가 모든 CT소견을 네 단계로 평가하였고, 평가는 임상적 정보와 내시경 소견 정보 없이 이루어졌다. CT 소견과 CRP, CDAI의 관계를 평가하기 위해 Spearman's rank correlation과 logistric regression analysis를 이용하였다. CT 소견에 대한 두 영상의학과 의사간 일치도는 ĸ statistic를 이용하였다.
      결과: CDAI는 두 조사자 모두에서 장벽의 조영 증강, 장벽비후의 두께, 과녁징후, 과혈관성, 주변부 지방층 침습의 CT 소견과 통계학적으로 유의한 상관관계를 보였다 (Spearman correlation coefficients, 0.435-0.782; p<0.05). CDAI는 CRP와 유의한 연관성을 보였다 (r=0.783; p<0.001). 또한 이러한 다섯 가지 CT소견은 CRP와도 유의한 상관관계를 보였다 (r=0.428-0.647; p<0.05). Binary logistic regression analysis 결과, 장벽비후의 두께 (p=0.043, Exp(B)=118.6) 와 과혈관성 (p=0.018, Exp(B)=35.2) 이 CDAI에 영향을 미치는 인자였다. 크론씨 병의 질병 활성도를 예측하기 위한 다섯 가지 CT 소견의 AUROC는 0.829-0.901였다. 두 조사자 간에서 CT 소견의 일치도는 good interobserver agreement (ĸ=0.671) 를 보였다.
      결론: 크론씨 병의 CT 소장 조영술 영상소견은 CDAI, CRP와 관련성이 있다.

      Purpose: Few studies have correlated computed tomography (CT) enterography findings in the Crohn's disease patients with Crohn's Disease Activity Index (CDAI) and C reactive protein (CRP) concentrations. Our study evaluates CT enterographic findings of active Crohn's disease and examine whether small bowel inflammation of CT enterography correlates with CDAI and CRP.
      Methods and Materials: All patients with inflammatory bowel disease at our institution between March 2007 and March 2011 who had a CRP, ileocolonoscopy, and CT enterography performed within 14 days were identified. Twenty-eight patients (16 women, 12 men) had Crohn's disease in the terminal ileum, proven by endoscopic biopsy, were enrolled in our study. Crohn's Disease Activity Index was assessed through clinical or laboratory variables. CT enterography was performed after 120 mL of intravenous contrast material was administered at 4mL/sec, with 40-75 seconds delay, following 2 liters of sorbitol solution taken orally over 90 minutes prior to scan. Five different CT parameters were examined: mural hyperenhancement, mural thickness, mural stratification, comb sign (vascular enlargement of the vasa recta), and mesenteric fat density. Two gastrointestinal radiologists independently assessed all CT images by four-point scale and were blinded to all clinical and endoscopic information. Correlations between CT parameters, CRP, and CDAI were assessed using Spearman's rank correlation and logistic regression analysis. The interobserver agreement between two radiologists for each CT parameters was also examined by using ĸ statistic.
      Results: The CDAI was significantly correlated with CT mural hyperenhancement, mural thickness, mural stratification, comb sign and mesenteric fat density in both reviewers (Spearman correlation coefficients 0.435-0.782; p<0.05). It also showed the correlation with the sum of scores of five CT parameters (r=0.496, 0.601; p<0.05) and CRP (r=0.783; p<0.001). The CRP was significantly correlated with all five CT parameters in both reviewers (r=0.428-0.647; p<0.05). The binary logistic regression model indicated that mural thickening (p=0.043, Exp(B)=118.6) and comb sign(p=0.018, Exp(B)=35.2) influenced on severity of CDAI. The area under the receiver-operating characteristics (AUROC) of five CT parameters for the prediction of disease activity in Crohn's disease is 0.829-0.901. CT parameters demonstrated the good interobserver agreement (ĸ=0.671).
      Conclusion: CT enterographic findings are correlated with CDAI and CRP in the patients with Crohn's disease.
