摘　　要：目的探讨乳腺疾病超声筛查工作中不同因素对病灶检出率的影响。方法选取在我院行乳腺超声筛查的患者900例,随机分为3组(检查时间分别为2 min、4 min及6 min),每组300例,扫查后记录每组病灶检出率,分析各组病灶检出率的差异。采用多因素回归分析研究患者年龄、扫查时间及探头频率对病变检出情况的影响。结果 2 min扫查组与4 min、6 min扫查组的病灶检出率比较差异均有统计学意义(均P<0.05),而4 min扫查组与6 min扫查组的病灶检出率比较差异无统计学意义。多因素回归分析结果显示,患者年龄、扫查时间及探头频率对超声筛查的病灶检出率均有一定影响,其作用从大到小依次为患者年龄(OR=4.3)、扫查时间(OR=4.1)及探头频率(OR=3.3)。结论在乳腺超声筛查工作中,探头频率、患者年龄及扫查时间均对病灶检出率有显著影响。Objective To investigate the effect of different factors on the detection rate of ultrasound in breast lesions screening.Methods A total of 900 patients were divided into 3 groups according to the scanning time (2 min,4 min,6 min).Each group included 300 patients.Lesions detection rate was recorded for each group,then the difference of lesions detection rate among three groups was analyzed.Multivariate regression analysis was used to study the effect of influence factors,including age,scanning time and probe frequency.Results Significant difference of detection rate was found between 2 min group and the other two scanning time groups (all P<0.05),but no significant difference between 4 min group and 6 min group.Factors of he patient's age,scanning time and probe frequency had certain influence on the detection rate of ultrasound in breast lesions screening.Its role in decreasing order were patient's age (OR=4.3),scanning time (OR=4.1) and probe frequency (OR=3.3).Conclusion Factors of patient's age,scanning time and probe frequency have effect on the detection rate of ultrasound in breast lesions screening.
