What is the purpose of using a radiopaque dye?
The radiopaque dye enhances the contrast in micro CT imaging, allowing for better visualization of the coronary vessels.
How is the perfusion process initiated?
The process begins by opening the abdominal cavity and cannulating the abdominal aorta to allow for fluid introduction.
What is micro CT imaging?
Micro CT imaging is a high-resolution imaging technique used to visualize internal structures in small animals.
Why is vessel ligation necessary?
Ligation helps direct the perfusion and prevents potential leakage during the filling process.
What are the benefits of this method?
This method provides a reliable way to visualize coronary anatomy, which is crucial for cardiovascular research.
Can this technique be applied to other vascular studies?
Yes, the technique can potentially be adapted for other vascular studies in different models.
