目的建立正常大鼠钼靶软Ｘ线影像质量标准，并应用于氟中毒大鼠骨骼变化研究。方法应用钼靶和钨靶Ｘ线对３０只正常Ｗｉｓｔａｒ大鼠对照拍片，采用主、客观相结合方法对两组Ｘ线照片质量进行评定，而后用钼靶软Ｘ线对氟中毒大鼠骨骼改变动态观察。结果钼靶较钨靶Ｘ线照片骨纹清晰，骨与软组织对比明显，Ｘ线影像密度值与密度差较大，提高了氟中毒大鼠氟骨症检出率和诊断正确性。结论钼靶软Ｘ线摄影是诊断氟中毒大鼠氟骨症的有效方法，可推广应用
Objective To establish the normal mammography soft X-ray image quality standard and apply it to the skeletal changes of fluorosis rats. Methods A total of 30 normal Wistar rats were treated with molybdenum target and tungsten target X-ray. The quality of the two groups was evaluated by the combination of the primary and the objective methods. Then, the skeletal changes of fluorosis rats Dynamic observation. Results Compared with the tungsten target, the mammography showed a clear bone pattern, a clear contrast between the bone and the soft tissue, and a large difference between the density and density of the X-ray image, which improved the detection rate and diagnostic accuracy of skeletal fluorosis in fluorosis rats. Conclusion Soft mammography is an effective method to diagnose skeletal fluorosis in rats with fluorosis
