彩超、CT平扫与增强CT检查在急性胰腺炎诊断中临床对比研究 　　[摘要] 目的 探讨彩超、CT平扫和增强CT检查对急性胰腺炎的诊断价值。 方法 彩超、CT平扫加增强扫描检查98例急性胰腺炎患者，对彩超、CT平扫和CT增强检查诊断急性胰腺炎的阳性率、诊断重症胰腺炎的检出率进行分析比较。 结果 彩超对急性胰腺炎诊断的阳性率为63.3%，CT平扫为80.6%，CT增强为81.6%，CT与彩超相比差异有统计学意义（P ＜ 0.05）；CT增强对重症胰腺炎的检出率要高于彩超和CT平扫，差异有统计学意义（P ＜ 0.05）；彩超对胆源性胰腺炎的检出率要高于CT平扫和增强（P ＜ 0.05）。 结论 彩超、CT平扫和CT增强检查对急性胰腺炎的诊断有重要的临床意义。 　　[关键词] 急性胰腺炎；彩色多普勒超声；体层摄影术；X线计算机；增强扫描；诊断 　　[中图分类号] R576.05 [文献标识码] A [文章编号] 1673-7210（2012）04（a）-0119-02 　　 　　Comparative study of ultrasongraphy, CT and enhanced CT in the diagnosis of acute pancreatitis 　　AN Lixiang1 LI Yanhui2 HAN Jie1 HOU Xiaoying1 　　1.Department of Functional, the Central Hospital of Handan, Hebei Province, Handan 056001, China; 2.Department of Medicine, Hebei University of Engineering, Hebei Province, Handan 056001, China 　　[Abstract] Objective To study the value of CT, enhanced CT and ultrasonography in the diagnosis acute pancreatitis. Methods The cases of ninety-eight with actue pancreatitis were examined by ultrasongraphy CT and enhanced CT. Their manif-estations were compared and analyzed. Results The positive rate of ultrasongraphy was 63.3% in all patients with acute pancreatitis, the positive rate of CT was 80.6%, and the positive rate of enhanced CT was 81.6%.The findings of ultrasongraphy and CT showed siginificant difference (P ＜ 0.05). The detection rate of enhanced CT in severe acute pancreatitis was superior than ultrasongraphy and CT scan, the findings were significant difference between them (P ＜ 0.05). The detetion rate of ultrasongraphy in gallstone pancreatitis was superior than CT, with significant difference between them (P ＜ 0.05). Conclusion ultrasongraphy, CT and enhanced CT in the diagnosis of actue pancreatitis has important clinical significance. 　　[Key words] Acute pancreatitis; Ultrasonography; Tomography; X-ray computed; Enhanced scan; Diagnosis 　　 　　急性胰腺炎是一种临床常见的急腹症，起病急，症状重，并发症多，如不及时诊治，病死率较高，因此，早期及时明确诊断和发现并发症对选择有效的治疗方案、降低病死率具有重要的临床意义。近年来医学影像学迅速发展，彩超、CT的普及，大大提高了临床对急性胰腺炎的早期诊断水平，
