The micro -CT imaging has become popular due to the involvement of different types of radiopaque contrast agents and recently nanoparticles based ExiTron nano available for micro - CT imaging of soft tissues.
Micro CT scan is used to scan X-rays imaging 3D and it is used on much smaller scale with less resolution.
The accumulation of phagocytosis cells like kupffer cells in liver and macrophages in the spleen increase reduction of the signalsof soft tissues. That is why it is essential to find the toxicity of this nanomaterialin CT imaging prior to its application in pharmacology studies.
