超声弹性成像与超声造影对乳腺病灶鉴别诊断价值的研究

The Value of Ultrasonic Elastography and Contrast-enhanced Ultrasonography in the Differential Diagnosis of Breast Lesions

目的:探讨超声弹性成像与超声造影技术在乳腺肿瘤的诊断中价值。材料与方法:对行乳腺肿物切除的175位患者共175个病灶术前进行二维超声、彩色多普勒超声、超声弹性成像及超声造影检查。依据超声弹性成像5分法和超声造影相关指标,分别对肿物进行良恶性诊断。结果:175例乳腺病灶,良性123例,恶性52例。超声弹性成像诊断乳腺恶性肿瘤的敏感性为71.2%,特异性为92.7%,准确率为86.3%。超声造影技术诊断乳腺恶性肿瘤的敏感性为78.8%,特异性为96.7%,准确率为91.4%。两者之间的差异无统计学意义。结论:超声弹性成像与超声造影技术有助于乳腺肿物的鉴别诊断,二者具有互补作用。

Objective： To explore ultrasonic elastography and contrast-enhanced ultrasonography in the differential diagnosis of breast tumor. Materials and methods： 175 patients with 175 lesions were enrolled in the study. They were all examined with 2D-ultrasound, color Doppler, ultrasonic elastography and contrast-enhanced ultrasonography before surgery. The diagnosis was made according to ultrasonic elastography and contrast-enhanced ultrasonography respectively. Pathological results were as standard criterion. Results： 123 benign tumors and 52 malignant tumors were confirmed by pathology. The sensitivity, specificity and accuracy for diagnosing malignant breast lesions was 71.2%o, 92.7% and 86.3% by ultrasonic elastography, while 78.8%, 96.7% and 91.4% by contrast-enhanced ultrasonography. Conclusions： Ultrasonic elastography and contrast-enhanced ultrasonography are useful in the differential diagnosis of breast tumor and they can compensate for each other to make an accuracy diagnosis.
