| 目的 应用超声背向散射积分(IBS)技术对乳腺肿块进行检测,探讨IBS值在乳腺肿瘤鉴别诊断中的价值。方法 对152例以乳腺肿块收入院拟进行手术的患者行IBS联机分析测定和常规彩超检测,术后进行病理追踪,按病理结果分组分析,确立诊断乳腺肿瘤的IBS的临界值 。然后设立验证组,验证该标准诊断乳腺疾病的敏感度、特异度、阳性预测值(+PV)、阴性预测值(－PV)、准确率。结果 各组疾病的IBS值的诊断点各不相同(P均＜0.05)。PPI与SDI结果的一致性较好,PPI(SDI)的敏感度高,AII特异度高。PPI或AII与常规彩超结合,上述指标均有明显的提高。结论 应用IBS值有助于乳腺肿块良恶性的鉴别,IBS为无创判定乳腺疾病提供了一项数字半量化的新指标;与常规彩超联合应用可取长补短,可明显提高乳腺超声检查的准确率。 |

| Objective To evaluate the role of ultrasonic integrated backscatter (IBS) in the differential diagnosis of breast masses. Methods Totally 152 patients with breast masses enrolled in the study. The criterion of the IBS values of different pathological results of breast masses were established. The criterion in control group (n=148) were verified by sensitivity, specificity, positive predictive value (+PV) and negative predictive value (－PV) and accuracy. Results The criterion of IBS values (unit: dB) was statistically different (all P<0.05) in different breast masses. PPI results with the SDI had good agreement. PPI (SDI) had high sensitivity while AII had high specificity. Combining PPI or AII with general ultrasound (including the two-dimensional image, color Doppler, pulsed Doppler), the above-mentioned criterion were significantly improved, respectively (P<0.05). Conclusion The values of IBS contribute to the identification of benign and malignant breast masses. It may be a new criterion quantification, especially, while in combination with general ultrasound, it can markedly increase the accuracy in diagnosis of breast masses. |
