目的 对比分析高频超声、乳腺钼靶对乳腺肿块良恶性的诊断价值.方法 随机将本院于2019年12月～2020年12月纳入的60例乳腺肿块患者分为两组,给予观察组高频超声检查,给予参照组乳腺钼靶检查,分析应用价值.结果 对于良性乳腺肿块,两组诊断准确率无明显差异;而对于恶性肿块,观察组准确率高于参照组(P ＜ 0.05).结论 在对乳腺肿块良恶性的诊断中,高频超声、乳腺钼靶对良性肿块诊断准确性无明显差异,但是对于恶性肿块,超声的诊断准确性较高.“,”Objective To compare and analyze the diagnostic value of high frequency ultrasound and mammography in the diagnosis of benign and malignant breast masses. Methods Sixty patients with breast masses enrolled in our hospital from December 2019 to December 2020 were randomly divided into two groups. The observation group was given high-frequency ultrasound examination, and the reference group was given mammography examination to analyze the application value. Results For benign breast masses, there was no significant difference in the diagnostic accuracy between the two groups; for malignant masses, the accuracy rate of the observation group was higher than that of the reference group (P＜0.05). Conclusion In the diagnosis of benign and malignant breast masses, high-frequency ultrasound and mammography have no significant difference in the diagnostic accuracy of benign masses, but for malignant masses, ultrasound is more accurate.
