摘　　要：目的探讨单面增感屏暗盒x线胶片拍摄成像在大骨节病检查中的应用价值。方法使用单面增感屏暗盒及常规黑纸暗袋装x线胶片，确定相匹配的曝光条件，分别对大骨节病病区220名在校儿童进行右手腕骨对照摄片检查，采用FJ个人剂量仪测试儿童接受X散射线照射程度，评价照片质量及诊断效果。结果单面增感屏暗盒组儿童接受的X散射线照射剂量为（207±39）μsv／h，黑纸暗袋组儿童接受的X散射线照射剂量为（1425±63）μsv／h，两种方法比较，差异有统计学意义（f=140．16，P〈0．05）。单面增感屏暗盒与黑纸暗袋摄片成像优质率分别为94．55％（104／110）和92．73％（102／110），两种方法比较，差异无统计学意义（X2=0．26，P〉0．05）；单面增感屏暗盒组照片良好率[96．36％（94／110）]明显优于黑纸暗袋组[44．55％（49／110），X2=70．92，P〈0．05]。结论单面增感屏暗盒比黑纸暗袋摄片成像的X射线照射剂量小，对人体的损害小，摄片成像质量优越，在大骨节病病区X线检查中具有良好的实用价值。Objective To explore the application value of single intensifying screen cassette in examination of Kashin-Beck disease through X-ray photographing. Methods Single intensifying screen cassette and traditional changing bag with exposure conditions were used to check right wrists of 110 children in Kashin- Beck disease areas. The FJ personal dosimeter was used to measure exposure dose. Photo graphing quality and diagnosis effect were assessed. Results The radiation dose of children in single intensifying screen cassette group was （207 ± 39）μsv/h, while in the traditional changing bag group was （1425 ± 63）μv/h. The difference between the two groups was statistically significant（t = 140.16, P 〈 0.05）. The high-quality photograph rate of the two methods was 94.55% （104/110） and 92.73% （102/110）, respectively, and the difference was not statistically significant（P 〉 0.05）. The good photo rate in the single intensifying screen cassette was 96.36% （94/110）, which was significantly higher than that of the traditional changing bag group[44.55%（49/110）,X2 = 70.92, P 〈 0.01 ]. Conclusions X-ray radiation dose in single intensifying screen cassette group is smaller than that of the traditional changing bag group, and the image quality of the radiograph of the new method is also superior. It has a good practical value in the X-ray examination of Kashin-Beck disease.
