摘要
目的:通过对比和讨论CR、DR设备的成像质量,分析非晶态硅探测器的临床应用价值。方法:随机选取我科采用非晶态硅探测器的DR设备存储的受检者胸部图像853例,CR图像853例,所选取的资料均为体检科正常者,比较其图像质量。结果:图像质量在肺门结构(x2=3.621,P=0.057)、纵隔(x2=2.002,P=0.157)、肋膈角(x2=1.001,P=0.317)等方面,DR相比CR设备就有明显优势,但不具有统计学意义(P>0.05);肺纹理(x2=4.038,P=0.044)、肺段(x2=7.448,P=0.006)方面具有显著优势,具有统计学意义(P<0.05)。CR图像评定中:甲级(88%),乙级(10%),丙级(2%),DR图像评定中:甲级(91.2%),乙级(5.1%),丙级(3.7%)。结论:非晶态硅平板探测器具有较高的图像质量,同时对于延长X线管使用寿命,减少X线对患者及工作人员的辐射都具有重要意义。
Objective： To discuss the clinical value of DR amorphous silicon detector by comparing our department CR, DR device image quality. Methods： 855 cases receiving examination with DR and another 855 with CR were randomly selected for comparison of the image quality. Results： In the hilar structures（x2=5.621;P=0.057）, mediastinum（x2=2.002; P=0. 157）,and other aspects of the costophrenic angle（x2= 1.001 ：P=0.317）, DR devices havesignificant advantages compared to CR, but not statistically significant （P〉0.05）, markings（x：=4.038;P=0.044）, lung segment（S=7.448;P=0.006） has a significant advantage, with statistical significance （P〈0.05）. CR Image Evaluation： Grade A（88%）, B（10%）, C（2%）, DR Image Evaluation： Class A（91.2%）, B（5.1%）, C（3.7%）. Conclusion： Amorphous silicon flat panel detector has a high image quality. For the extended X-ray tube life, reduced X-ray of the patient and staff radiation are important.
