摘要研制了一种用于颈脑血管病(CVD)检测的超声分析系统。 在这项研究中,通过患者的前额检测到的声音信号进行了分析,使用短时傅立叶变换方法,并根据频谱的强度对数据进行了评估。共49例CVD患者和34名对照者进行了研究,并根据光谱的强度分为四个等级。CVD组真阳性率为83.7%,对照组真阴性率为94.1%。该分析系统的敏感性和特异性分别为83.7%和5.9%。脑血管狭窄/闭塞、脑动脉瘤和动静脉畸形/瘘的真阳性率分别为85.7%、73.7%和100%。未来的目标是临床应用,作为脑部疾病的大规模筛查测试。该系统显示了这方面的潜力,并将继续进一步开发。
Abstract A sonic analysis system was developed for the detection of cervical and intracranial vascular disease (CVD). In this study, sound signals detected through the patient’s forehead were analyzed using a short-time Fourier transformation method, and data were evaluated according to the intensity of spectra. A total of 49 patients with CVD and 34 control subjects were studied and classified into four grades according to the intensity of the spectra. The true positive rate was 83.7% in patients with CVD, and the true negative rate was 94.1% in the control group. The sensitivity and specificity of this analysis system were 83.7% and 5.9%, respectively. The true positive rates for cerebral stenosis/occlusion, cerebral aneurysm, and arteriovenous malformation/fistula were 85.7%, 73.7%, and 100%, respectively. The future goal is clinical application as a mass-screening test for brain disease. This system shows potential for this purpose, and further development will continue.
