1. Bronchography may reveal dilated enlarged ducts of hypertrophic gland.

2. The diagncstic effects of choice transbronchoscopic bronchography with 60% megluc- amine diatrizoate compound in 31 cases were observed.

3. CONCLUSION:Combination of transcatheter bronchial brushing, forceps and selective bronchography has made it possible to obtain a higher diagnosis rate (97 6%).

4. Methods Under DSA guideness, selective bronchography by balloon catheter combined with fiberoptic bronchoscopy was studied in 27 patients with hemoptysis, contrast medium was 76% urografin.

5. Objective To analyze retrospectively 251 cases of pulmonary diseases using imageology manifestation and bronchography.

6. Objective To evaluate the effects of meglumine diatrizoate mucilage ( MDC ) used as contrast medium in bronchography.

7. Objective:To evaluate the value of conventional CT(CCT), high resolution CT(HRCT)and bronchography in the diagnosis of bronchiectasis, and to choose the optimal diagnostic method.

8. Conclusion: After chest radiography HRCT is the first choice valuable method for the diagnosis of bronchiectasis . It may reduce the need of bronchography in the diagnosis of bronchiectasis .

9. Materials and methods: 150 patients with chronic cough, sputum and hemoptysis in whom bronchiectasis was suspected underwent bronchography using nonionic or ionic agent respectively.

10. We report a precisely displayed and successfully treated primary tracheal adenoid cystic carcinoma that was presented with the help of virtual bronchography images.

11. Objective:To evaluate the role of digital X ray machine in bronchography.

12. Purpose : To evaluate the effect of a nonionic agent and an ionic agent in bronchography.

13. Objective: To research the effects of treating hemoptysis due to bronchiectasis and bronchography of selective filling bronchus with meglumine diatrizoate - Yunnan Baiyo colloidal solution.

14. Materials and Methods Chest film, conventional CT scanning,( ) HRCT scanning and digital subtraction bronchography (DSB) were carried out in 42 patients with clinically-proved bronchiectasis.

15. Materials and Methods: HRCT was performed in 69 patients with bronchiectasis . 34 of them also had digital subtraction bronchography(DSB).
