中文摘要:
      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。
英文摘要:
      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 lesion 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.
