Xenon increases the attenuation coefficients of tissues in which it dissolves and, therefore, enhances lipid-rich material. The authors evaluated xenon enhancement for computed tomography. Patients and normal subjects were given xenon in subanesthetic concentrations and were scanned in a large aperture CT scanner. Patients tolerated 30-50% inhaled xenon well. Cerebral tissues and lung were enhanced by this concentration of xenon. Xenon inhalation in subanesthetic concentrations will be a useful technique for characterizing abnormal lipid tissues and for estimating cerebral blood flow.
氙气会增加其溶解的组织的衰减系数，因此，会增强富含脂质的物质。作者评估了氙气增强在计算机断层扫描中的作用。对患者和正常受试者给予亚麻醉浓度的氙气，并在大孔径CT扫描仪中进行扫描。患者对30%-50%的吸入氙气耐受性良好。这种浓度的氙气可增强脑组织和肺部。吸入亚麻醉浓度的氙气将是一种用于表征异常脂质组织和估计脑血流量的有用技术。
