Rupture of intracranial aneurysm without any warning is very likely in asymptotic patients and high rate in rupture risk brings the necessity of development and utilization of high-resolution imaging modalities. Here, the assessment of scanning acoustic microscopy (SAM) in identifying cerebral aneurysm, is done. The aneurysm’s dome samples, obtained from 6 male and 6 female patients with and without subarachnoid hemorrhage, are analyzed and the acoustic impedance values of samples from female patients are found statistically higher than those of samples from male patients. Besides, acoustic impedance of a sample from a male patient without subarachnoid hemorrhage has higher value than those of samples from other male patients who all have subarachnoid hemorrhage, while, in female patients, this discrepancy is not observed. Consequently, monitoring capacity of SAM, by measuring acoustic impedance values in humans with and without subarachnoid hemorrhage, indicates its potential in the diagnosis of cerebral aneurysm instability.

渐进患者极有可能在没有任何警告的情况下破裂颅内动脉瘤，高破裂风险会带来开发和利用高分辨率成像方式的必要性。在这里，完成了扫描声波显微镜（SAM）识别脑动脉瘤的评估。分析了从有和没有蛛网膜下腔出血的6例男性和6例女性患者获得的动脉瘤穹顶样本，发现女性患者样本的声阻抗值在统计学上高于男性患者。此外，没有蛛网膜下腔出血的男性患者的样品的声阻抗值比所有都患有蛛网膜下腔出血的其他男性患者的样品的声阻抗值更高，而在女性患者中没有观察到这种差异。所以，
