PET STUDY OF RETINAL PROSTHESIS FUNCTIONALITY

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。 这项研究的目的是观察视网膜植入者的大脑是否发生变化。 受试者将在6个不同日期接受6次放射性示踪剂正电子发射断层扫描（PET）。 PET是一种特殊的照相机，可以拍摄放射性示踪剂在体内运动的照片。 这项研究的放射性示踪剂是18 FDG，这是一种放射性糖，以非常少量的方式注入血液，并将作为脑回路变化的指标。 葡萄糖是大脑用作燃料的糖。

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 purpose of this study is to see if there are brain changes in people who have a retinal implant. Subjects will receive six Positron Emission Tomography (PET) scans with a radiotracer on six different days. PET is a special camera that takes pictures of the movement of a radiotracer in the body. The radiotracer for this study is 18FDG, which is a radioactive sugar that is injected into the bloodstream in very small amounts and will serve as an indicator of brain circuit changes. Glucose is the sugar the brain uses for fuel.
