目的 针对乳腺癌患者应用超声、CT与X线钼靶方法进行检查，并分析各检查方法的检出情况。方法 选择208例患 者作为本次研究对象，均为2015年7月至2017年7月在本院进行治疗的乳腺癌患者，将其以投掷法随机分成四组， 其中行超声、X线钼靶与CT检查的52例患者分别作为对照组Ⅰ、对照组Ⅱ与对照组Ⅲ，三种方法联合检查的52例 患者作为观察组，比较分析各组的检出率情况。结果 三组对照组的阳性检出率情况无明显差别，无统计学意义 (P>0.05)，观察组的阳性检出率明显高于其余三组，其差异有统计学意义(P<0.05)；对照组Ⅰ超声诊断出淋巴结 (67.31%)与肿块(92.31%)的表现率明显高于对照组ⅡX线钼靶诊断出的表现率(38.46%)与(65.38%)；对照组ⅡX线钼 靶诊断出钙化(42.31%)与钙化伴肿块(32.69%)的表现率明显高于对照组Ⅰ超声诊断的表现率(7.69%)与(5.77%)，其 差异有统计学意义(P<0.05)。结论 超声、CT与X线钼靶三种检查方法结合可大大提高乳腺癌阳性检出率，建议广泛 应用。

Objective To investigate the detection condition of ultrasound, x-ray mammography and CT on diagnosis of breast cancer. Methods 208 cases with breast cancer in our hospital from July 2015 to July 2017 were selected and divided into four groups according to throwing method. 52 cases given ultrasound, x-ray mammography and CT were respectively seen as control groupⅠ, control groupⅡ, control group Ⅲ, 52 cases given joint inspection were seen as observation group. Positive conditions of the three groups were compared. Results Positive detection rate of the three control groups had no obvious difference, the difference was not statistic significant (P>0.05), positive detection rate of observation group was obviously higher than other 3 groups, the difference was statistic significant (P<0.05), express ratio of lymph gland and tumor diagnosed by ultrasound in control groupⅠ (67.31%, 92.31%) was higher than those of x-ray mammography in control groupⅡ (38.46%, 65.38%), express ratio of calcification and calcification with tumor diagnosed by x-ray mammography in control groupⅡ (42.31%, 32.69%) was higher than those of ultrasound in control groupⅠ(7.69%, 5.77%), the difference was statistic significant (P<0.05). Conclusion The combination of ultrasound, x-ray mammography and CT can significantly improve breast cancer positive detection rate and is worthy of wide application.
