This study was undertaken to evaluate image quality and level of discomfort during examination with various contrast media(meglumine ioxitalamate: Telebrix $30^{circledR}$ , diatrizoate sodium: Hypaque $50^{circledR}$, sodium ioxaglate ＋ meglumine ioxaglate: Hexabrix <TEXulcorner$320^{circledR}$</TEX> , iopamidol: Iopamiro $300^{circledR}$ , iodized poppyseed oil: $Lipiodol^{circledR}$ and barium sulfate: Baritop$^{circledR}$and various radiographic contrast techniques(eye dropping: group 1, single injection to the superior punctum: group 2 and continuous injection to the superior punctum: group 3) on dacryocystorhinography in dogs. The results were as follows; 1. The Image quality of radiographic contrast technique of continuous Injection of contrast media(group 3) was better than the other techniques. 2. Average scores for dacryocystorhinography quality of sodium ioxaglate ＋ meglumine ioxaglate, iopamidol, barium sulfate, iodized Poppyseed oil, meglumine ioxitalamate and diatrizoats sodium were 3.67${pm}$0.47, 3.67${pm}$0.47, 3.50${pm}$0.50, 3.33${pm}$0.75, 2.50${pm}$0.50 and 2.50${pm}$0.76, respectively in group 3. 3. Diatrizoate sodium produced more discomfort than the other media. It was considered that the best radiographic contrast technique of dacryocystorhinography was continuous injection of contrast media to the superior punctum and sodium ioxaglate + meglumine ioxaglate, iopamidol, iodized Poppyseed oil and barium sulfate were the excellent contrast media for dacryocystorhinography in dogs.
