X线测量BMD特制专用暗匣与双能X线骨密度仪对照性研究
Research on tailor-made X ray BMD cassette in comparison with dual purpose X ray bone density meter
【摘要】 目的开发研制实用新型测量骨密度(BMD)特制专用暗匣,改造X线摄片法测量骨密度(BMD)。方法用自制的TiNeng20X线骨密度仪和X线片暗匣等,制成测量BMD的专用暗匣,与美国(OsteometerMediTech公司)生产的DTX200双能X线骨密度仪共同测量,验证专用暗匣的实用性和可靠性。结果特制专用暗匣测出的级值与BMD相关对应,诊断阀值为,男≤12级,女≤13级正常;男13~14级、女14~15级骨量减少;男>14级,女>15级骨质疏松;男>16级、女>17级为严重骨质疏松。两种方法测量数据相关对应的总吻合率达92.69%。结论测量BMD特制专用暗匣的功能齐全,弥补了X线摄片法“三个没有”的缺点,使之成为一种实用新型且简便经济测量BMD的方法。
【Abstract】 Objective Purpose To explore a tailor-made cassette for measuring bone density as an improvement to the x-ray photographic method.Method To remodel the self-made Ti Neng-20 X-ray bone density meter and x-ray cassette into a tailor-made cassette for measuring bone density and verify its practicability and reliability against the DTX-200 manufactured by Osteometer MediTech.The diagnosed valve value of the tailor-made cassette is:Male≤12 scale and female≤13 scale:NormalMale 13~14 scale and female 14~15 scale:bone mass lossMale>14 scale and female>15 scale:Male and female>16 scale:severe osteoporosis 92.69% of the results measured by the two above-mentioned methods tally with each other.Conclusion Tailor-made cassette for measuring bone density, making up the defects of x-ray photographic method, is a new economical tool.
