体检筛查结合钼靶X线与超声对乳腺癌的诊断价值

目的：评价体检筛查结合钼靶X线与超声对乳腺癌的诊断价值,以提高乳腺癌的检出率。方法：选择经手术病理证实的乳腺癌患者19例,对其X线、超声征象及其敏感性进行统计学分析。结果：①检出乳腺癌的敏感性分别为：体检筛查0.34%,钼靶X线68.4%（13/19）,高频超声68.4%（13/19）,两者比较差异无统计学意义;综合两者影像检查的敏感性为100%（19/19）,明显优于单一钼靶X线或超声检查（P〈0.05）。②钼靶X线与超声显示乳腺癌的征象有毛刺肿块、微细钙化、肿瘤血管及多种不典型征象。③钼靶X线对微细钙化检出率为47.4%（9/19）,高频超声检出率为26.3%（5/19）。钼靶X线检出钙化型乳腺癌比高频超声敏感（P〈0.05）。④高频超声对乳腺癌血流信号检出率为68.4%（13/19）,钼靶X线显示异常血管征为31.6%（6/19）。高频超声检测血流信号明显优于钼靶X线（P〈0.01）。结论：体检筛查是重要的乳癌早期诊断方法,钼靶X线与高频超声作用互补,综合两种影像检查能显著提高乳腺癌的检出率。

The Diagnostic Value of the Combination of the Medical Screening,Mammography X-ray and Ultrasonography in Women with Breast Gancer

Objective：To evaluate the combination of medical screening,molybdenum X-ray and ul trasonography in the diagnosi s of breast cancel,in order to improve the detecti on rate of breast cancer.Methods：19 casesof breast.cancer con.rmed by surgery and pathoogy,the signs ofmolybdenum X-ray and ultrasonography and their sensi tivity were analyzedstatisticay.Results：①the sensitivity of detection of breast cancer was as follows：medical screening 0.5%：manmlography x-ray,68.4%（13/19）：high-frequency ul trasound,68.4%（13/19）.There was rio stati sticsignificances between mammography x-ray and high-frequency ul ttasound insensitivity of detection of breast cancer：the sensi tivi ty could be～raisedto 100%（19/19）by combining the two methods and superior to the singemethod used（P0.05）.②Mammography X-ray and ul trasonograph,showssigns of breast cancer had burr mass,micro-calcification,tumor bloodvessels and a variety of atypical signs.③The detection r8te of a.micro-calcification of mammography x-ray was 47.4%（9/19）：the detectionrate of a micro-calcification of high-frequency ultrasound was 26.3%（5/19）.the mammography x-ray was more sensitive than high-frequencyultrasound in detection rete of the calcified breast cancer（P0.05）.④The detection rate of breast cancer＇s blood flow was 68.4%（13/19）by high-frequency ultrasound;the detect Jon rate of abnormalvessels was31.6%（6/19）by mammography X-ray.High-frequency ultrasound was superiorto mammography X-ray in detection of abnormat bloodflow（P0.01）.Conclusion：Medi cal screening is an important method of early diagnosis of breast cancer.The mammography X-ray and high-frequency ultrasound complement each other and combining these two methods could significantly improved the detection rate of breast cancer.
