目的：提高食管癌的检出率。材料与方法；28例食管癌均经手术病理或细胞学证实，采用三种对比研究方法；（1）、低张口服造影剂前后；（2）、快速增强扫描前后；（3）、薄层扫描后多方位重建，结果：低张口服造影后，可以较清晰地显示狭窄的管腔及内壁，并有利于早期食管癌的检出；快速增强扫描有利于判断食管癌的外侵；而重建后则可多方位观察病灶的整体。结论：通过改进食管癌的CT扫描方法，可以明显提高食管癌的显示率和检出率。
Objective: To improve the detection rate of esophageal cancer. Materials and Methods; 28 cases of esophageal cancer were confirmed by operation pathology or cytology, using three comparative study methods; (1) before and after oral administration of contrast agent; (2), before and after rapid enhanced scan; (3), thin layer Multi-dimension reconstruction after scanning, results: After oral angiography with low Zhang, can clearly show the narrow lumen and the inner wall, and is conducive to the detection of early esophageal cancer; rapid enhanced scan is conducive to the determination of esophageal cancer invasion; and reconstruction Afterwards, the entire lesion can be observed in multiple directions. Conclusion: By improving the CT scanning method of esophageal cancer, the display rate and detection rate of esophageal cancer can be significantly improved.
