高频超声、乳腺X线检查及乳腺血氧功能成像在乳腺肿块诊断中的价值

The clinical value of high frequency ultrasound, mammography and breast blood-oxygen function imaging system in diagnosis of breast masses

目的比较高频超声、乳腺X线检查以及乳腺血氧功能成像在乳腺肿块诊断中的价值。方法回顾性分析高频超声、乳腺X线检查及乳腺血氧功能成像在89例乳腺肿块中的诊断结果，比较它们诊断各类乳腺病变的敏感性和特异性，并分析漏诊原因。结果高频超声、乳腺X线检查以及乳腺血氧功能成像对乳腺癌的敏感性分别为80．00％、70．00％、50．00％；特异性分别为94．94％、98．73％、97．47％。高频超声检查对于乳腺纤维腺瘤的敏感性较高，为98．11％；乳腺X线检查对乳腺良性病变普遍不敏感，但特异性较高。结论高频超声、乳腺X线检查及乳腺血氧功能成像是临床诊断乳腺癌的有效手段；乳腺X线检查及乳腺血氧功能成像对乳腺纤维腺瘤及乳腺囊性病变的诊断价值不高；乳腺血氧功能成像可以提高非哺乳期乳腺慢性炎症的诊断准确率。

Objective To compare the diagnostic value of high frequency ultrasound, mammography and breast blood-oxygen function imaging system in diagnosis of breast masses. Methods The images of 89 breast masses by high frequency uhrasound, mammography and breast blood-oxygen function imaging system were reviewed. The study compared the sensibilities and specificities of the three methods in the masses and analyzed their cause of missed diagnosis. Results The sensitivity of the diagnosis of breast cancer by high frequency ultrasound, mammogra- phy and breast blood-oxygen function imaging system were 80.00% , 70.00% and 50.00% , respectively. The speci- ficity of the diagnosis of breast cancer by them were 94.94% ,98.73% and 97.47% ,respectively. There were sigmfi- acant differences in diagnosis of breast benign lesion among the high frequency ultrasound, mammography and breast blood-oxygen function imaging system. The sensitivity of high frequency ultrasound in detecting fibroadenoma of breast was 98.11% higher than the other methods. Mammography was insensitive to the benign breast lesions, but its speci- ficity was high. Conclusions High frequency ultrasound, mammography and breast blood-oxygen function imaging system are the highly effective diagnostic tool for breast cancer, but the diagnostic value of mammography and breast blood-oxygen in breast fibroadenoma and in cystic disease of breast aren＇ t high. Breast blood-oxygen function imaging system can enhance the accuracy of the diagnosis of mammary inflammation.
