Objective To research the application value of direct digital radiograph (DDR) in nasal bone imaging. Methods One hundred cases were examined by DDR, 30 cases of them were examined by two methods both DDR and conventional radiography. All digital images were post-processed with “MUSICA”(Multi-Scale Image Contrast Amplification), incision and largamente, analyzed and diagnosed by experienced two radiologists and two technicians. Results One hundred cases of nasal bone, soft tissue of nose were showed excellent in DDR, and satisfactory cases were 95 and 92, respectively. Forty-six cases of nasal bone fractures were found. Thirty cases were examined by both DDR and conventional radiography, images of nasal bone, soft tissue of nose were showed, satisfactory cases were 28 in DDR; and satisfactory cases were 6(χ2=20.05,P0.05)and 10 (χ2=15.06,P0.05)respectively in conventional radiography. Nasal bone fracture was found in 11 cases and 18 cases (χ2=5.14,P0.05) in conventional and digital radiography, respectively. Conclusion DDR images of nasal bone, soft tissue of nose was excellent, more fractures were discovered than conventional radiography. Image quality of DDR is better than conventional radiography in nasal bone imaging.
