摘要
目的评价MicroPure辅助诊断技术对钙化超声显示率及提高乳腺癌诊断准确率的应用价值。方法对我院63例患者的68个病灶行常规超声、x线钼靶及配有MicroPure辅助诊断技术的超声检查，分别描述病灶钙化及BI—RADS分级情况，全部病灶行穿刺活检或手术得以病理确诊。结果①以钼靶显示病灶钙化作为对照，常规超声的钙化显示率为80．6％，MicroPure技术的钙化显示率为100％。②常规超声、钼靶、MicroPure辅助诊断技术对诊断乳腺良恶性病灶的ROC曲线下面积分别为0．916、0．857和0．970。③常规超声BI—RADS分级为3级的3个病灶经MicroPure技术诊断为4级，病理结果为恶性。结论MicroPure辅助诊断系统可以显著提高微小钙化的超声显示率，同时可以提高超声诊断乳腺癌的准确率，尤其对常规超声BI—RADS分级3～4级之间的患者，提高倾向性比率。
Objective To evaluate the value of MicroPure software system in the display of calcification and diagnostic accuracy of breast carcinoma. Methods Sixty-three patients with 68 breast lesions were checked by conventional ultrasound,X-ray and MicroPure software technique. The calcification was described and the lesions were classified with BI-RADS. All cases were pathologically confirmed by biopsy or operation. Results ①Compared to the detection rate for calcification of X-ray,the display rate of conventional ultrasound was 80.6% ,and the display rate of MicroPure software technique was 100%. ②The area under the curve of diagnosing benign and malignant of breast lesions was 0. 916,0. 857 and 0. 970 respectively with ultrasound,X-ray and MicroPure software technique. ③Three lesions was classified Ⅲ in BI-RADS with conventional ultrasound,and Ⅳ in BI-RADS with MicroPure software. The pathologic results were malignant. Conclusions MicroPure software system obviously raised the ultrasonic display rate of calcification,meanwhile, it raised the diagnostic accurate rate of breast cancer. It especially raised the tendency rate for the patients who were classified between Ⅲ and Ⅳ in BI-RADS.
