超声与钼靶X线诊断乳腺肿块对比分析

Compared Stu4y on Breast Masses by Ultrasound and Molybdenum TargetRadiography

对５８例乳腺肿块的超声显像、钼靶Ｘ线摄影及术后病理结果进行对比分析，良性肿块４０例，超声与Ｘ线诊断敏感性分别为８５％和７８％；乳腺癌１８例，超声与Ｘ线诊断敏感性分别为８９％和８３％。对漏误诊病例分析显示，超声检查漏诊率高，而Ｘ线检查误诊率高，发病年龄＜４５岁组，超声诊断敏感性高于Ｘ线摄影，分别为１００％和７１％，年龄＞４５岁组，超声诊断敏感性低于Ｘ线摄影，分别为８２％和９１％，两种方法联合应用诊断良性肿块符合率为９２．５％，恶性肿块符合率９４％。两种方法诊断良恶性肿块的Ｘ￣２检验无显著性差异（Ｐ＞０．０５），提示：超声与钼靶Ｘ线对乳腺肿块的诊断，各具优势和局限性，如能发挥其优势来互补局限性，当能提高乳腺肿块的诊断水平。

The results of ultrasound,molybdenictarget radiography and pathology were analysed for58 cases of breast masses. The study showed that di-agnostic corresponding rates of ultrasound and radio-graphy are 85%and 78%respectively in 40 cases ofbenign masses and 89%and 83%respectively in 18cases of malignent masses.The values had no signifi-cant difference by X￣2 test (P<0.05)between ultra-sound and radiography.The missed rate of ultra-sound and misdiagnostic rate of radiography arehigh.The diagnosing ability is different between ul-trasound and radiography in various age groups ofbreast cancer. In the group below 45 years old,themissed rate of ultrasound is higher than radiography(100%vs 71%respectively),while in the group over45,that of ultrasound is lower than radiography(82%vs 91%respectively).The rates of diagnosingbenign and maiignent masses are raised to 92.5%and94%respectively when ultrasound and radiographyare performed jointly. We conclude that ultrasoundand molybdenic target radiography have separate ad-vantages and limits in diagnosis of breast cancer,and if we can give play to other′s strong points to offsetone′s weakness each other,the diagnostic effect willbe promoted.
