病灶位置对乳腺超声弹性成像检查结果的影响

目的探讨病灶位置对乳腺超声弹性成像（UE）检查结果的影响。方法对681例患者共885个乳腺病灶进行了超声弹性成像检查，根据病灶底部距体表的距离（D）分为3组（I组：D〈1cm；Ⅱ组：1cm≤D〈2cm；Ⅲ组：D〉2cm），UE评分采用改良5分法，≤3分判为良性，≥4分判为恶性。结果三组患者UE诊断恶性病变的敏感性、特异性、准确性无显著差异。结论病灶位置对UE检查结果无显著影响。

Effects of location of lessions on diagnostic results of ultrasonic elastography

Objective To evaluate the effects of location of lesions on diagnostic results of ultrasonic elastography(UE). Methods 681 patients with 885 breast lesions were examined by UE. In cording to the dis- tance(D)from the button of lesion to body surface,the patients divided into three groups(Group Ⅰ:D < 1 cm; Group Ⅱ : 1 cm≤ D < 2 cm ; Group Ⅲ : D > 2 cm). Ultrasonic elastogram was evaluated according to the im- proved five-score. The lesions with Score 4,5 were diagnosed as malignancy, and the lesions with Score less than 3 were diagnosed as benignancy. Results There was no significant difference in the sensitivity,specificity, and accuracy of UE for diagnosing breast malignance in three groups. Conclusion The location of lesions did not affect the diagnostic results of UE.
