TOMOSYNTHESIS

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。这项研究的目的是评估体内断层合成或采样不足的CT对大鼠肺灌注的影响。成像研究将评估断层合成或欠采样CT使用IsoVue 300等常规造影剂多次注射在肺部进行3D成像和灌注评估的方式。当用于大鼠肺部疾病模型时，图像可以用来量化正常和功能障碍的病例。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The goal of this research is to asses in vivo tomosynthesis or undersampled CT for lung perfusion in rats. The imaging studies will assess the way tomosynthesis or undersampled CT can perform 3D imaging and perfusion assesment in the lung using multiple injections of a conventional contrast agent such as Isovue 300 . Images can be used to quantify the normal and dysfunctional cases when used with lung disease models in rats.
