[目的]探讨全自动乳腺容积成像(ABVS)对乳腺病灶诊断效果,及影响诊断效果的危险因素。[方法]经过手术或穿刺病理检查证实的40例乳腺病灶患者使用彩色多普勒超声诊断仪进行常规超声、彩色超声与ABVS等,并对变量进行回归分析。[结果]常规超声诊断乳腺良、恶性病灶的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为:86.4%、87.1%、86.9%、70.5%、94.7%。ABVS诊断乳腺疾病的敏感性、特异性、准确性、阳性预测值、阴性预测值分别为96.1%、91.9%、94.5%、74.0%、94.1%。经Logistic回归分析,“火山口”征,病灶内微小钙化,病灶边缘、患者年龄对乳腺恶性病灶的诊断效能高。[结论]ABVS系统基于乳腺全容积扫查的特点,有助于提高超声医师对乳腺病变的检出率。
[Objective] To investigate the diagnostic value of automatic breast volume imaging (ABVS) for breast lesions and the risk factors for the diagnosis. [Methods] 40 cases of breast lesions confirmed by operation or biopsy were examined by color Doppler sonography with conventional ultrasound, color ultrasound and ABVS. The variables were analyzed by regression analysis. [Results] The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of conventional ultrasound in the diagnosis of benign and malignant breast lesions were 86.4%, 87.1%, 86.9%, 70.5% and 94.7%, respectively. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ABVS in diagnosing breast diseases were 96.1%, 91.9%, 94.5%, 74.0% and 94.1%, respectively. Logistic regression analysis, “crater ” sign, the lesion within the micro-calcification, the edge of the lesion, the patient’s age on the diagnosis of malignant breast lesions with high efficacy. [Conclusion] The ABVS system is based on the feature of full volume scanning of the breast and helps to improve the detection rate of the breast lesions by ultrasound doctors.
