【摘要】 目的 探讨直接数字化X 线摄影( direct digitized radiography, DDR) 在鼻骨摄影中的
应用价值。方法 对100 例DDR 鼻骨侧位影像采用图像后处理方法中多级图像对比增益法, 又称
“ 交响乐”功能( multi-scale image contrast amplification, MUSICA) 、影像切割与局部放大等功能进行后
处理, 同时数字随机法对其中30 例行普通X 线摄影。由放射科经验丰富的医、技师各2 名对所有鼻
骨影像进行分析, 评价其对鼻骨骨折、鼻骨整体及鼻周软组织的显示。结果 100 例DDR 鼻骨影像
中, 诊断骨折46 例, 鼻骨整体及鼻周软组织显示满意的分别为95 和92 例; 对照组30 例DDR 鼻骨影
像发现骨折18 例, X 线片发现骨折11 例, 漏诊7 例( χ2 = 5. 14, P < 0. 05) , 30 例DDR 影像中, 鼻骨整
体及鼻周软组织显示满意的均为28 例; 普通X 线片两者显示满意的分别为6 例( χ2 = 20. 05, P <
0. 05) 和10 例(χ2 = 15. 06, P < 0. 05) 。结论 DDR 影像比普通X 线影像能更好的显示鼻骨和鼻周软
组织, 提高鼻骨骨折的检出率。

【Abstra ct 】 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, P < 0. 05 ) and 10 ( χ2 = 15. 06, P < 0. 05 )
respectively in conventional radiography. Nasal bone fracture was found in 11 cases and 18 cases ( χ2 =
5. 14, P < 0. 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.
