目的用受试者工作特性曲线评价超声检查和乳腺X线摄影术诊断乳腺癌的价值。方法选取手术前行超声检查和乳腺X线摄影术检查的88例乳腺疾病患者(其中乳腺癌病患者38例,乳腺良性疾病患者50例)。对超声检查和乳腺X线摄影术的影像学资料进行分析,以手术病理诊断为金标准,分为肯定良性、可能良性、不确定、可能恶性、肯定恶性5个诊断等级。采用SPSS 13.0软件建立受试者工作特性曲线,计算曲线下面积。结果超声检查和乳腺X线摄影术诊断乳腺癌的曲线下面积分别为0.828(SE=0.045)和0.811(SE=0.053),两者之间差异无统计学意义(Z=0.245,P>0.05)。结论超声检查和乳腺X线摄影术对乳腺癌的诊断准确性中等,两者差异无统计学意义。在基层医院进行乳腺癌影像学检查时,可首选无创、简便、经济、有效的超声检查。
Objective To evaluate the diagnostic value of ultrasonography and mammography in the diagnosis of breast cancer using the working characteristic curves of the subjects. Methods Eighty-eight patients with breast diseases (including 38 with breast cancer and 50 with benign breast disease) underwent ultrasound examination and mammography. On the ultrasound and mammography imaging data analysis to the surgical pathology diagnosis as the gold standard, is divided into positive benign, may be benign, uncertain, may be malignant, certainly malignant five diagnostic levels. The SPSS 13.0 software was used to establish the working characteristic curve of the subject and calculate the area under the curve. Results The area under the curve of ultrasound examination and mammography in the diagnosis of breast cancer were 0.828 (SE = 0.045) and 0.811 (SE = 0.053) respectively. There was no significant difference between the two groups (Z = 0.245, P> 0.05) . Conclusion The diagnostic accuracy of ultrasound and mammography in breast cancer is moderate, but the difference between them is not statistically significant. In the primary hospital for breast cancer imaging examination, the preferred non-invasive, simple, economical and effective ultrasound examination.
