目的:探讨血管阻力指数在乳腺肿块良恶性鉴别诊断中的价值。方法:收集110例乳腺肿块患者,首先用二维超声对肿块做常规扫查,然后用彩色多普勒超声观察肿块血流情况,并测量阻力指数等参数。结果:结合肿块二维超声声像图特征及血管阻力指数,与手术病例对照,37例恶性病例诊断符合率约94.6%[73例良性病例诊断符合率约93.2%。表明阻力指数对乳腺占位性病变的良恶性鉴别诊断具有重要价值。结论:阻力指数作为超声检查中一项重要指标,结合二维超声征象,可以大大提高诊断的准确性。
Objective: To investigate the value of vascular resistance index in the differential diagnosis of benign and malignant breast tumors. Methods: Totally 110 patients with breast lumps were collected. The lumps were routinely scanned by two-dimensional ultrasound. Then the color flow of the lumps was observed by color Doppler sonography and the parameters such as resistance index were measured. Results: According to the characteristics of two-dimensional ultrasonography and vascular resistance index, the coincidence rate of diagnosis of malignant and benign cases was 94.6%. [The coincidence rate of 73 cases of benign cases was 93.2%. Show that the resistance index of breast lesions of benign and malignant differential diagnosis of great value. Conclusion: The resistance index as an important index in ultrasound examination, combined with two-dimensional ultrasound signs, can greatly improve the diagnostic accuracy.
