Esophageal radiography using two different air-contrast techniques was used to examine 30 patients with Barrett's esophagus and 18 controls. All patients had upper gastrointestinal endoscopy and biopsy of the esophagus. The radiographs were randomized, masked, and then interpreted by two radiologists blinded to the endoscopic and biopsy diagnosis. Depending upon the diagnostic strategy of the radiologist, sensitivity varied from 0.36 to 0.83 and specificity from 0.56 to 1.00. A typical receiver-operating-characteristic curve was generated. Esophageal radiography is effective in identifying those patients who have stricture and ulceration as a complication beyond the epithelial transformation. However, because of low sensitivity, it is not a satisfactory method for identifying most cases of Barrett's esophagus.
采用两种不同的气钡双重造影技术对30例巴雷特食管患者和18例对照者进行食管造影检查。所有患者均接受了上消化道内镜检查及食管活检。X线片随机分组、遮盖处理，然后由两位对内镜和活检诊断不知情的放射科医生解读。根据放射科医生的诊断策略，敏感性在0.36至0.83之间，特异性在0.56至1.00之间。绘制了典型的受试者工作特征曲线。食管造影对于识别那些出现狭窄和溃疡作为上皮化生以外并发症的患者是有效的。然而，由于敏感性较低，它不是识别大多数巴雷特食管病例的令人满意的方法。
