数字化钼靶X线与彩超应用BI-RADS分级诊断乳腺癌的价值比较

Application of BI-RADS grading to compare the value of color doppler ultrasound and X-mammograpyon on the diagnosis of breast cancer

目的：通过对彩超与钼靶X线应用BI-RADS分级在乳腺癌诊断上的比较并分析其优缺点，以探讨结合二者应用于临床上诊断乳腺癌的价值。方法通过分析我院手术与病理结果证实的82例乳腺癌患者的钼靶X线和彩超影像表现及其BI-RADS分级，两者检查结果与病理检查结果对照。结果诊断率比较中彩超组（a）为87.80%，钼靶X线组（b）为75.60%，两者联合组（c）为95.24%，差异组间比较Pa：b=0.237，Pa：c=0.014，Pb：c=0.017；恶性诊断率彩超组为66.66%，钼靶X线组为73.33%，两者联合组为86.66%，差异组间比较Pa：b=0.164，Pa：c=0.003，Pb：c=0.001；BI-RADS等级比较中联合应用组2~3级与4级诊断率高于彩超组及钼靶X线组，差异有统计学意义（P＜0.05）。结论两者联合应用可相互补充，对BI-RADS分级具有很高的灵敏度，将两者联合应用于临床可以提高乳腺癌患者的诊断率。

Objective Application of BI-RADS grading to study the value of color doppler ultrasound and X-mammograpyon on the diagnosis of breast cancer. Methods 82 cases of breast cancer patients with color doppler ultrasound and X-mammograpyon data were selected. The test results of two methods werecompared with pathological findings. Results Compared with the pathological examination, the Ultrasound diagnosis rate was 87.80%, the X-ray mammography group（b） of 75.60%, combination of the two methods group（c） was 95.24%, the difference between groups Pa：b=0.237, Pa：c=0.014, Pb：c=0.017;the Ultrasound group malignant diagnosis rate was 66.66%, mammography X-ray group malignant diagnosis rate was 73.33%, both combined group malignant diagnosis rate was 86.66%, the difference between groups Pa：b=0.164, Pa：c=0.003, Pb：c=0.001, BI-RADS rating comparison application-level group combined 2-3 with four diagnostic ultrasound group and higher than X-ray mammography group, the difference was statistically significant P〈0.05. Conclusion Combined with color doppler ultrasound and X-mammograpyon can improve the diagnostic rate of breast cancer patients.
