"The Vitrea Lung Density Analysis software provides CT values for the pulmonary tissue from CT thoracic datasets. Three-dimensional (3D) segmentation of the left lung and right lung, volumetric analysis, density evaluations and reporting tools are integrated in a specific workflow to offer the physic...
第3名医师独立测定肺动脉直径/主动脉直径比值,并采用Lung Density Analysis(Vital VitreaFx工作站,Vital公司)测定CT定量参数,包括CTLowW:两肺CT值<-920 Hu的体积;CTMediumW:两肺CT值为-920~-720 Hu的体积;CThighW:两肺CT值>...

技術發展源自美國密西根大學放射科系的分子影像中心。他們研發的這套稱作肺密度分析(Lung Density Analysis, LDA)的軟體,藉由分析患者肺部的電腦斷層(Computed Tomography, CT)影像,可以計算出肺部阻塞的細微狀況。最近,這套軟體通過了FDA的510(K),醫師可以用LDA系統來分析COPD患者的肺部影像,進而了解COPD對患者吐氣和吸...
(FVC),forced expiratory volume in one second (FEV1%)and ratio of forced expiratory volume in one second to maximum vital capacity (FEV1/FVC)were recorded.FACT-Digital lungTM data analysis software was used to obtain the CT quantitative parameters of lung volume (LV),mean lung density (MLD)...
These data provide no indication of other factors such as small and large airways disease, and loss of elastic recoil, which may contribute to airflow limitation, or disruption of the pulmonary vascular bed which may also affect CT lung density. 展开 ...
Lung function examination showed that FEV1/FVC = 0.8. d Thin-slice chest CT image of COPD in an 82-year-old female subject. She is 152 cm tall, non-smoker, and has a Radscore of 3.17. e Lung density analysis diagram showed that both lungs are mostly ...
Lung tissue, blood, and air determine the physical density of the lung and hence the attenuation measured on CT scans. These components are not homogeneously distributed throughout the lungs, and their relative proportion changes continuously during respiration. The objective of this study was to mea...
