SPECT/CT Imaging for Mouse Disease Tracking
Description
SPECT/CT imaging combines nuclear imaging and X-ray imaging to study mice. It uses a radionuclide, which is a radioactive tracer, that is injected into the animal. After the tracer spreads through the body, the mouse is scanned and the images are reconstructed into a 3D dataset.

结合SPECT-CT扫描可同时提供有关特定目标器官的解剖学和功能信息。
单光子发射计算机断层扫描(SPECT)成像通过伽马相机直接检测经静脉注射的放射性物质所发出的辐射,从而实现对生物活性的无创成像,而不仅仅是器官的静态图像。
当与计算机断层扫描(CT)结合时,SPECT-CT成像可提供代谢数据和解剖学信息,这些信息在多种应用中具有重要价值。
本视频将阐述单光子发射计算机断层扫描-计算机断层扫描(SPECT-CT)成像的基本原理,并简要介绍 SPECT-CT 图像的采集、重建和分析方法。
SPECT-CT 成像利用两种独立的成像方式——SPECT 和 CT,将功能评估与解剖学信息相结合,从而提高整体诊断能力。
在CT中...
