目的：探讨超声弹性成像技术在指导BI‐RADS 3类病灶随访方面的价值。方法回顾同时行常规超声检查和超声弹性成像检查的患者资料，筛选形态规则、边界清楚、弹性评分1～2分的BI‐RADS 3类病灶作为研究对象，共164例患者331个病灶，随访时间＞1年，比较随访期间病灶大小、二维表现、弹性评分是否发生明显变化。结果331个病灶随访时间12～48月，平均213．月，330个病灶复查后超声提示考虑可能良性（997．％，330／331），1个复查后提示BI‐RADS 4a（03．％，1／331），术后病例证实为纤维腺瘤。结论弹性评分2分以下的BI‐RADS 3类病灶可降至BI‐RADS 2类，推荐形状规整、边界清楚的弹性评分1～2分的BI‐RADS 3类病灶1年随访。

Objective To evaluate whether patients with BI‐RADS category 3 breast lesions can be managed safely by 1‐year follow‐ups using ultrasound elastography .Methods Data from 164 patients who underwent conventional B‐mode ultrasound and ultrasound‐based elasticity examinations from September 2009 to March 2014 ,and had BI‐RADS category 3 lesions that appear to be circumscribed and oval in shape with elasticity scores of 1 -2 ,were retrospectively reviewed .Results Of 331 BI‐RADS category 3 lesions that originally appeared circumscribed and oval in shape in 164 women ,the mean follow‐up period was 21 3. months (range ,12-48 months) ,and 330 (99 7.% ) were unchanged at follow‐up and considered probably benign .One lesion was upgraded to BI‐RADS category 4a ,and a subsequent biopsy pathologically confirmed it was a fibroadenoma .Conclusions BI‐RADS category 3 lesions with elasticity scores of 2 or lower can be reclassified as BI‐RADS category 2 lesions .A 1‐year follow‐up may be adequate for women undergoing screening ultrasonography ,which are found to have BI‐RADS category 3 lesions that appear to be circumscribed and oval in shape with elasticity scores of 1-2 .
