目的 :比较食管早癌在不同机器的X线征象和检出率。方法 :92例食管早癌 ,用国产 5 0 0mAX线机进行非低张和低张双对比两种造影方法比较 ,再和数字成像双对比造影比较 ,对粘膜破坏、小充盈缺损、小龛影和管壁改变X线征象在食管早癌的糜烂型、斑块型、乳头型和平坦型的检出率进行对照。结果 :国产机器非低张双对比造影检出率 71.4% ,低张双对比造影 83.3% ,数字成像双对比造影为 10 0 %检出率。任何检查方法对平坦型显示率都很低。病变浸润粘膜下层的低张法优于非低张法 ,分别为 94.7%和 80 % ,浸润粘膜层分别为 83.3%和 5 7.1%。数字成像对两种浸润层次的检出率是 10 0 %。结论 :食管早癌检查数字成像双对比造影显示病变最好 ,低张双对比造影优于非低张双对比造影。
OBJECTIVE: To compare X-ray signs and detection rates of early esophageal cancer on different machines. Methods: 92 cases of esophageal precancerous lesions were treated with a 50000mA X-ray machine in our hospital. The comparison of two non-hypotonic and low-contrast double-contrast angiography methods was compared with that of double-contrast digital imaging. The effects of mucosal damage, small filling defect, And wall changes in X-ray signs of esophageal cancer in early erosion, plaque, papillary and flat detection rate were compared. Results: The detection rate of non-low contrast double contrast was 71.4%, that of low contrast double contrast was 83.3%, and that of double contrast imaging of digital imaging was 10%. Any inspection method for flat display rate is very low. Lesion infiltration submucosa hypotonic method is better than non-low-stretch method, respectively, 94.7% and 80%, infiltration mucosa were 83.3% and 51.1%. Digital imaging of the two infiltration levels of the detection rate is 100%. Conclusion: The double contrast imaging of digital imaging of early esophageal cancer examination showed the best lesion, low contrast double contrast was better than non-low contrast double contrast angiography.
