TOMOSYNTHESIS

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 本研究的目的是评估大鼠肺灌注的体内断层合成或欠采样CT。成像研究将评估断层合成或欠采样CT使用多次注射传统造影剂（如Isovue 300）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，图像可用于量化正常和功能障碍病例。

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.
