Abstract:
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)μsv/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.
