| [摘要]目的：研究正常体检筛查情况下，乳腺病灶的年龄、部位的分布情况，同时对扫查时长对漏检影响进行了单因素分析。方法：随机将在我院超声科行乳腺体检筛查的受检者进行年龄分组，对受检者的乳腺病灶分为囊肿、导管扩张，乳腺结节，腋窝结节。扫查时长分为2分钟扫查组（平均每侧乳腺扫查1分钟，包含双侧腋窝），4分钟扫查组（平均每侧乳腺扫查2分钟，包含双侧腋窝）及6分钟扫查组（平均每侧乳腺扫查3分钟，包含双侧腋窝）。扫查完成后分别记录超声发现病灶的情况。每组300人，共900人参与了本次研究。扫查时长对漏检的影响采用Logistic 回归分析。显著性检验水平采用P<0.05。结果：共900例体检者进入研究组，其中18-30岁年龄层右乳发现病变有26例，左乳发现病变有19例，双侧均发现病变的有48例；31-45岁年龄层，右乳发现病变有44例，左乳发现病变有57例，双侧均发现病变的有161例；46-55岁年龄层，右乳发现病变有24例，左乳发现病变有19例，双侧均发现病变的有53例：大于55岁年龄层，右乳发现病变有20例，左乳发现病变有17例，双侧均发现病变的有26例。根据Logistic回归分析4分钟和6分钟分别与2分钟比较阳性率均有差别，其中4分钟的OR值为1.65（P=0.003），6分钟OR值为2.01（P=0.000）。单独比较4分钟、6分钟阳性率差别无统计学意义（P=0.239）结论：超声乳腺筛查是发现乳腺病变的重要工具，扫查时长影响乳腺病变的检出率。 |

| Abstract: |
| [Abstract]Objective: To investigate the clinical value of the scanning duration of breast health examination. Methods: Patients scanned by routine breast ultrasound examination are divided into 2 minutes (scan each breast every one minute, including bilateral axillaries), 4 minutes (scan each breast every two minutes, including bilateral axillaries) and 6 minutes group (scan each breast every three minutes, including bilateral axillaries) by different scanning duration. Made a record of ultrasound lesions after scanning. Each group had 300 persons. In total, 900 persons were in this research. The influence of scanning duration on lesions detection was analyzed by Logistic regression analysis. Significance test level was P<0.05. Results: According to Logistic regression analysis, there are significant differences between 2 minutes scanning and 4 minutes scanning or 6 minutes scanning, in which the OR of 4 minutes is 1.65(P=0.003) and the OR of 6 minutes is 2.01(P=0.000). But there are not statistical significance between 4 minutes and 6 minutes in positive rate（P=0.239）.Conclusion: scanning duration of breast screening ultrasound examination had influence on the detection rate. |
