贲门区正面观诊断早期贲门癌

本文报道29例病理证实的早期贲门癌,着重讨论胃双对比造影贲门区正面观对诊断早期贲门癌的重要作用。详细叙述了贲门区正面观的显示方法,对其正常X 线表现及早期癌肿征象进行了分析。强调摄片体位与透视下动态观察钡剂流动是正确应用该方法的关键。认为贲门区正面观以双对比像显示率高,正常形态恒定,局部结构表现异常清晰,极易发现微小病变。将其作为胃双对比造影常规摄片体位可明显提高贲门早期癌肿的诊断水平。

Comparison of CT and Fiberoptic Bronchoscopy in the Evaluation of Bronchial Disease

CT was compared to FB in 51 cases to study the value of CT for visualizing bronchial disease. CT finding was positive in 46 of 51, and suggested CT was closely correlated with FB. 3 of 5 with false negative were endobronchial lesions, 2 were submacosal diseases. By camparison, it was found conventional tomography was a useful method in diagnosing the bronchial disease.
