| 目的 评价多功能角度调节器配合防护罩对氟骨症X线摄片的应用价值。方法 用常规摄片、调节器配合防护罩摄片及调节器摄片检查78例患者的前臂和小腿,对比照片质量和诊断结果。用高压电离室巡侧仪测患者体面、侧面、底面1和2 m处剂量率,评价其防护效果。结果 调节器配合防护罩摄片和调节器摄片比常规摄片提高照片优质率39%,提高诊断准确率37%(χ2=43.33、43.98及17.76、14.56,P＜0.01)。前臂和小腿距离X线中心1和2 m处常规摄片的剂量率均值分别为1198、934及1439、1175μSv/h;调节器配合防护罩摄片分别为80.6、39.4及95.6、59.5μSv/h;单项摄片分别为375.7、187及447、226.3μSv/h。 结论 角度调节器配合防护罩摄片是检查氟骨症功能障碍患者前臂和小腿有效的专用装置。 |

| Objective To evaluate the value of the multifunctional angle regulator with shields in skeletal fluorosis X-ray radiography. Methods Conventional radiography, regulator with shields and regulator for radiography were used to examine the forearms and shanks of 78 patients, and then the quality of the photos and the diagnostic results were compared. The dose rates on patients' foresides, sides, and bottoms of division 1 and 2 m were measured by pressure ionization instrument. Results Regulator with shields and regulator for radiography had a higher rate of good quality than conventional radiography by 39%, and consequently the diagnostic accuracy rate were improved by 37%(χ2=43.33,43.98 and 17.76,14.56,P＜0.01). By conventional radiography the average dose rates on forearms and shanks 1 and 2 m away from X-ray axis were 1198, 934 and 1439, 1175 μSv/h, respectively; while regulator with shields and single regulator were used, corresponding average dose rates were 80.6,39.4 and 95.6,59.5 μSv/h and 375.7,187 and 447,226.3μSv/h,respectively. Conclusions Angle regulator with shields is effective devices to examine the forearms and shanks of the patients who are suffering from dysfunction of skeletal fluorosis. |
