高频超声与X线诊断乳腺肿瘤的价值比较及漏误诊原因分析

目的：探讨高频超声与X线对乳腺肿瘤的诊断价值及漏误诊原因。方法：对45例46个肿块经手术病理证实的乳腺肿瘤患者术前超声与X线摄片结果与病理结果进行对照分析。结果：高频超声与X线的诊断符合率分别为82.6%（38/46）、78.3%（36/46）,两者比较,无明显差异（P〉0.05）;两者相结合诊断符合率为95.7%（44/46）,分别与单种诊断符合率比较,均有较明显差异（均P〈0.05）。结论：单纯应用高频超声或X线诊断乳腺肿瘤,两者的病理诊断符合率相似,两者结合可提高诊断符合率。对可疑病例,一种检查未发现病灶的,有必要进行另一种检查作为补充。

Comparison of high frequency ultrasound with x-ray in diagnosis of breast cancer and cause of missed diagnosis or misdiagnosis

Objective：To approach the diagnostic value of breast cancer using high frequency ultrasound and x-ray and the causal of missed diagnosis or misdiagnosis.Methods： High frequency ultrasound,x-ray were performed for 43 cases of malignant breast cancer confirmed by operative pathos-biology.Results： The diagnose accordance rate of high frequency ultrasound was 82.6%（38/46） and x-ray 78.3%（36/46）,there was no obvious difference（P0.05）.The diagnose accordance rate of both high frequency ultrasound and molybdenum target x-ray was 95.7%（44/46）,and this accordance rate was obviously different from either high frequency ultrasound or molybdenum target x-ray（both P0.05）.Conclusion： Pathological diagnosis was similar between high frequency ultrasound and x-ray,but the combined exam can improve the diagnosis rate.
