为探讨佝偻病X线表现及其有关诊断指标,我们对1252例3周岁以下小儿进行了X线腕部摄片,诊断佝偻病者710例,现将有关资料分析如下。方法1979～1983年间,我们采用国产200～500mAX光机,条件为40千伏,15mAS,焦距为75cm,小焦点加用增感纸,时间为0.1～0.3秒。根据1977年全国佝偻病防治科研协作会议修订的佝偻病诊断标准,对我盟牧区896例(71.57%)、半农半牧区121例(9.66%)、城镇235例(18.77%)3岁以下小儿,摄腕骨片,其中,男性679例(54.23%),女性573例(45.77%)。由专人专项阅片测量,误差不超过1mm。
In order to explore the X-ray findings of rickets and its related diagnostic criteria, we performed radiographic wrist radiography on 1252 children under 3 years old and diagnosed 710 cases of rickets. The relevant data are as follows. Methods From 1979 to 1983, we used domestic 200 ~ 500mAX light machine under the conditions of 40 kV, 15 mAS and focal length of 75 cm. The small focus plus sensitized paper was used for 0.1 ~ 0.3 seconds. According to the diagnostic criteria for rickets in 1977, there were 896 cases (71.57%) in pasture area, 121 cases (9.66%) in semi-agricultural and semi-pastoral area, 235 cases (18.77%) in urban areas and children under 3 years of age There were 679 males (54.23%) and 573 females (45.77%). Special reading by the special measurement, the error does not exceed 1mm.
