无线双板DR临床应用价值探讨

The Clinical Application of Wireless Dual Plate Digital Diagnost

目的:探讨无线双板DR临床应用价值。方法:选取笔者所在医院经锐珂无线双板数字化X线摄影系统(DR)所摄的胸片240例(DR组),收集同期经普通X线机所摄的胸片240例(普通X线组)。对比两组胸片在曝光剂量、图像质量、工作效率、医疗质量等方面的差异。结果:DR组辐射剂量、摄片优质率、摄片废片率均明显优于普通X线组;DR组患者平均检查时间、平均获得报告时间均明显短于普通X线组;DR组误诊率、漏诊率及由漏、误诊引发的医疗事故和纠纷发生率均明显低于普通X线组,差异均有统计学意义(P<0.05)。结论:与传统X线摄影系统比较,无线双板DR的辐射剂量更低,图像质量、工作效率更高,在提高放射科检查质量及医疗服务水平方面具有重要的临床价值。

Objective： To investigate the clinical application of wireless dual plate digital diagnost.Methods： 240 patients received wireless dual plate digital diagnost （DR） were selected as DR group, while another 240 patients received X-ray machine photograph of the chest radiographs were selected as the ordinary X-ray group. The differences of radiation dose, image quality, work efficiency, medical quality and other aspects of both groups were compared. Results： In DR group, the radiation dose was 0.14 mGy, it was significantly lower than that of ordinary X-ray group （0.32 mGy）; the radiography quality rate of DR group was 85.42%, significantly higher than that of ordinary X-ray group （53.33%）; while the film scrap rate was 0%, significantly lower than those of the ordinary ray group （4.17%）; the average inspection time in the DR group was （0.25 ± 0.14 ） rain, and the average access time report was （2.62 ± 0.53）min, they were significantly shorter than that of the ordinary X-ray group; In DR group, the rate of missed diagnosis and misdiagnosis rate of leakage, misdiagnosis caused by medical disputes occurred rate were significantly lower than that in the ordinary X-ray group, the difference were statistically significant （P〈0.05）.Conclusion： Compared with traditional radiography system, the wireless double plate DR has lower radiation dose, higher image quality, and higher working efficiency, it has great value in improving radiology examination quality and medical service level.
