超声弹性成像与钼靶X线成像诊断乳腺疾病的对照研究

目的 探讨超声弹性成像(UE)与钼靶X线成像(MX-rP)诊断乳腺疾病的价值.方法 对80例女性患者共105个病灶术前行UE与MX-rP检查,以手术病理为诊断金标准,对比分析UE与MX-rP诊断乳腺疾病的准确性.结果 病理诊断良性59例(共79个病灶),恶性21例(共26个病灶).UE诊断乳腺恶性病变的敏感性、特异性和准确性分别为88.5%、96.2%、94.3%.MX-rP诊断乳腺恶性病变的敏感性、特异性和准确性分别为69.2%、92.4%、86.7%.UE诊断准确性高于MX-rP(P＜0.05).结论 UE诊断乳腺病变的准确性高于MX-rP,两者结合可提高乳腺良恶性病变诊断的准确性.

Comparative study of ultrasonic elastography and molybdenum X-ray photography in breast diseases

Objective To investigate the value of ultrasonic elastography and molybdenum X-ray photography(MX-rP) in diagnosing breast diseases. Methods Eighty female patients with 105 lesions in breast were examined with elastography and MX-rP. Pathology was used as the golden diagnosing criterion.The accuracy of ultrasonic elastography and MX-rP for diagnosing breast diseases was compared. Results Pathological examination showed that 79 nodules in 59 patients were benign and 26 nodules in 21 patients were malignant. The sensitivity, specificity, and accuracy of ultrasonic elastography were 88.5%, 96.2% and 94.3%, and those of MX-rP were 69.2%, 92.4%, 86.7%, respectively. Conclusions The accuracy of ultrasonic elastography is much higher than that of MX-rP. The combinative use of ultrasonic elastography and MX-rP can elevate the accuracy for differentiating the benign from malignant breast tumours.
