摘要
目的探讨乳腺超声弹性成像(UE)检查感兴趣区域大小对诊断结果的影响。方法将感兴趣区域(ROI)大小分别调节至<病灶大小的2倍及≥病灶大小的2倍,对127例患者共164个乳腺病灶进行了超声弹性成像检查,UE评分采用改良5分法。结果ROI面积<病灶大小2倍时,164个乳腺病灶的UE评分显著低于ROI面积≥病灶大小2倍的UE评分;且对乳腺恶性病变诊断的准确性显著降低。结论UE检查时应将ROI调节至病灶大小2倍以上。
Objective To evaluate the effects of region of interest on diagnostic results of ultrasonic elastography （UE）. Methods One hundred twenty seven patients with 164 breast lesions were examined by UE. The size of region of interest （ROI） was set 2 times less and 2 times greater than or equal to the area of lc..~ion respectively. Ultrasonic elastogram was evaluated according to the improved five-score. Results The UE scores of lesions and the accuracy of UE for diagnosing breast malignance were significantly lower when the size of ROI was less than 2 times of the area of lesion. Conclusion The size of ROI should be set 2 times more than the area of lesion during examination of UE.
