摘要
目的比较超微血管成像（superbmicrovascularimaging，SMI）与超声造影微血管成像（microvascularimaging，MVI）在乳腺肿物鉴别中的应用价值。方法对116例患者（116个乳腺病灶）行SMI及MVI检查，评价乳腺病灶的微血管构筑，比较两种方法诊断效能的差异。结果SMI及MVI诊断乳腺肿物的灵敏性、特异性及准确性分别为79，24％、90．48％、85．35％及88．68％、87．30％、87．93％。两者ROC曲线下面积分别为0．888和0．926。两种方法的诊断效能差异无统计学意义（P=0．212）。结论SMI及MVI能有效检出乳腺病灶内的微小血管和低速血流，有利于乳腺肿物鉴别诊断，两者诊断妁能相信，
Objective To compare the diagnostic efficiency of superb microvascular imaging （SMI） and contrast-enhanced ultrasonographic microvascular imaging （MVI） for differentiating breast lesions. Methods One hundred and sixteen patients with 116 breast lesions were first examined by grayscale ultrasound. Then SMI and MVI were performed on all patients. Microvascular architectures of breast lesions were depicted by both methods. The lesions were evaluated based on their microvascular architectures. The diagnostic efficacy of both methods were compared. Results The diagnostic sensitivity, specificity, and accuracy of SMI and MVI were 79.24 % , 90.48% , 85.35 % and 88.68% , 87.30 % ,87.93 %, respectively. The areas under the curve of SMI and MVI were 0. 888 and 0. 926. The diagnostic values of SMI and MVI were not statistically different （ P = 0.212）. Conclusions SMI can detect tiny vessels and depict microvascular architecture of breast lesions as MVI do, which is beneficial for breast tumor differentiation. The diagnostic efficacy of SMI is almost the same as MVI.
