数字乳腺钼靶X线摄影规范化操作与质量控制

Standardization operotion and quality control of digital breast mammography X-ray photography

目的探讨数字化乳腺钼靶X线摄影检查时执行规范化操作与定期质量控制，以提高其图像质量，从而为临床提供高质量影像资料，减少漏诊和误诊。方法对300例患者（年龄30～75岁）进行乳腺钼靶X线检查，完全按照规范化操作程序并定期质量控制，体位设计选择头尾位（CC）、内外斜位（MLO）或90。侧位（内外侧位ML）所得到的乳腺钼靶数字x线成像（DR）影像进行分析研究。结果所得数字乳腺钼靶DR图像质量显著提高，乳房组织、腺体结构、腋窝淋巴结及胸大肌等显示清晰，诊断达标率为99％。结论数字乳腺钼靶X线摄影的规范化操作并定期进行质量控制，可显著提高其图像质量，从而为临床诊断和治疗提供高质量影像资料和依据，提高诊断准确率。

Objective To explore the standardized operation and quality control of the digital mamrnography X-rays, in order to improve its image quality, provide high-quality images for clinic, and reduce misdiagnosis and missed diagnosis. Methods Three hundred cases （age range 30 to 75 years） underwent mammography X-ray inspection, in accordance with the standardized operation procedures and regular quality control entirely, the choices of position design included the head and tail （CC）, internal and external oblique （MLO） or 90°lateral （inside and outside the lateral ML）,the obtained digital mamrnography DR images were analyzed. Results The quality of digital mamrnography DR image, was significantly improved, breast tissue, glandular structures, such as axillary lymph nodes and pectoralis major were showed clearly, the diagnosis compliance rate was 99%. Conclusion The standardized operation of the digital rnamrnography X-ray photography and the periodic quality control, can significantly improve its image quality and provide high-quality image data to improve the diagnostic accuracy for clinical diagnosis and treatment.
