乳腺钼靶X线摄影技术的探讨

The approach of mammography technique

目的探讨乳腺钼靶X线摄影技术,提高乳腺摄影片的质量及其在临床诊断中的应用。方法对500例乳腺摄影片患者的年龄、乳腺类型、投照体位进行分类,总结乳腺钼靶X线摄影技术的要点及质量控制。结果500例乳腺X线检查,95%乳腺片满足临床诊断要求。乳腺分类中致密型86例(17.2%)、腺体型217(43.4%)、退化型147(29.4%)、萎缩型50(10%)。乳腺分型与各年龄段重叠较多。双侧对照,常规内外斜位及轴位基本满足诊断要求。结论乳腺钼靶片的成像质量对临床正确诊断的先决条件,充分的检查前准备,合适的检查体位及摄影参数的合理选择是取得高质量乳腺钼靶片的关键。

Objective To study the mammography technique to improved the film＂ s quality and to meet the clinical application. Methods The mammography of 500 cases were classified according to their age, breast type and projected position. The highlights and quality control of the mammography technique were summarized. Results Among the 500 cases, 95% met the clinical diagnostic demands. Of the grand type, 17.2% were dense type, 43.4% were adenoid type, atrophy and degeneration type were 10% and 29.4% respectively. The grand type and age range overlapped a lot. Routine MLO and CCM position of bilateral breasts mammography could mostly meet the diagnostic demands. Conclusion The quality of mammography is the precondition of exact clinical diagnosis. Sufficient pre-exam preparation, suitable position and parameter were the key point of high quality mammography.
