乳腺肿块彩色多普勒超声诊断的评价

Evaluation of Color Doppler Ultrasound Diagnosis of Mammary Cancer

目的评价二维超声图像特征对乳腺良、恶性肿块诊断及鉴别诊断的意义。方法应用高频二维超声对201例乳腺肿块患者进行检查,观察肿块的形态、边界、内部回声、病灶后方回声及有无微小钙化灶。彩色多普勒血流图着重观察乳腺良、恶性肿块的血流特征。所有病例均经手术治疗,并将超声诊断与手术病理诊断结果进行对照。结果201例乳腺肿块术后病理诊断为恶性者140例,良性61例。超声对恶性肿块的诊断总符合率为93.6%,误诊率为6.4%;良性符合率为91.8%,误诊率为8.2%。结论高频二维超声图像特征对乳腺恶性肿块具有较高的诊断价值,但对微小乳腺癌的诊断仍有局限性。

Objective: To evaluate the significances of two dimensional ultrasonograms in diagnosis and differential diagnosis of benign and malignant mammary tumor. Method: 201 patients of mammary tumor received the examination of high frequency two dimensional ultrasonogram, observing the form, the border, the echo intra and behind minor lesions, and the tiny calcification points were observed also. Color Doppler ultrasound emphasizes the blood stream characters of benign and malignant mammary tumor. All of the patients accepted operation therapy, the Comparisons between the ultrasound diagnosis and pathologic diagnosis were made. Results: 140 cases of the 201 patients with mammary tumor pathologically diagnosed as malignant tumors, and 61 cases as benign tumor. For the malignant tumors, the total rate of coincidence of diagnosis by ultrasonograms is 93.6%, and the rate of missed diagnosis is 6.4%. For the benign tumor, the total rate of coincidence is 91.8%, and the rate of missed diagnosis is 8.2%. Conclusion: High frequency two dimensional ultrasound has great diagnostic values for malignant mammary tumor, and it also has some limits for the tiny tumor.
