The purpose of this study is to evaluate the efficiency of the Biofield Diagnostic System (BDS) as an adjunct to established diagnostic techniques such as mammography and ultrasound in differentiating benign and malignant breast lesions. The clinical trial was conducted at the Tan Tock Seng hospital, Singapore. 103 women scheduled for mammography and/or ultrasound tests participated in the study. The BDS test recorded a sensitivity of 100%, specificity of 97.6%, and an accuracy of 98.1%. The area under the ROC curve was 0.988 which was slightly lower than that of ultrasound (0.994) and slightly higher than that of mammography (0.951). The BDS test has demonstrated high sensitivity and specificity values in the studied population. The accuracy is also comparable to that of diagnostic techniques like mammography and ultrasound. Thus, it is evident that BDS can be a fast and reliable adjunct tool for getting a secondary opinion on lesions with indeterminate mammographic and sonographic results.
本研究旨在评估生物场诊断系统 (BDS) 在辅助诸如乳房 X 光摄影和超声等既定诊断技术区分良性和恶性乳房病变方面的效率。该临床试验在新加坡陈笃生医院进行。103 名计划接受乳房 X 光摄影和/或超声检查的女性参与了该研究。BDS 测试的灵敏度为 100%，特异性为 97.6%，准确性为 98.1%。ROC 曲线下面积为 0.988，略低于超声（0.994），略高于乳房 X 光摄影（0.951）。BDS 测试在研究人群中表现出较高的灵敏度和特异性值。准确性也与乳房 X 光摄影和超声等诊断技术相当。因此，BDS 显然可以成为一种快速可靠的辅助工具，用于对具有不确定乳房 X 光摄影和超声结果的病变获得二次意见。
