What is microCT?
MicroCT is a high-resolution imaging technique used to visualize internal structures in small animals.
How does the contrast agent work?
The contrast agent enhances the visibility of blood vessels during imaging by making them opaque to X-rays.
What are the benefits of using this technique?
It is rapid, cost-effective, and allows for high-throughput analysis of vascular networks in live subjects.
Can this method be used for other types of studies?
Yes, it can be adapted for various studies involving vascular analysis and tumor research.
What precautions are taken during imaging?
Animals are anesthetized and securely positioned to minimize motion artifacts during scans.
What types of data can be obtained?
The technique provides detailed images of vascular networks, allowing for analysis of blood flow and tumor support.
