乳腺X线摄影若干技术要素的研究

A study of some technical essentials of X ray mammography

目的 通过对乳腺摄影若干技术要素的解析及研究 ,提高摄影质量及诊断准确性。方法 对 2 1家医院的摄影质量进行调研。对常用的增感屏 胶片组合的成像质量进行测试 ,并与计算机摄影进行比较研究。对摄影位置及操作技术进行研究。结果 乳腺摄影的重要影像细节显示及诊断要求的符合率甚低 ,均为 2 4% ,其主要原因在于机器设备不符合要求。国人乳腺摄影的加压以12kg左右为最佳。结论 机器设备成像性能的改进应引起必要的关注。

Objective To improve the quality of mammography and diagnostic accuracy by analyzing and studying some of the technical essentials of X ray mammography. Methods The mammography quality of 21 hospitals were investigated. The image quality of normal intensifying screen film combination was tested and compared with computerized mammography The filming positions and operating skills were studied Results The important mammography details that were displayed have low conformity with the diagnostic requirements, mainly due to non conformity of these equipment to the requirements The optimal pressure suitable for mammography of the Chinese women was around 12 kg Conclusion Necessary attention must be paid to the improvement of imaging features of these equipment The improved operating skills will greatly raise the detecting percentage of pathological changes of breasts
