Vascular imaging with contrast agent in hard and soft tissues using microcomputed-tomography.

Area of Science:

• Biomedical Engineering
• Medical Imaging

Background:

• Vascularization is critical for tissue survival and regeneration, making its study essential for tissue engineering.
• Various imaging techniques exist for visualizing vasculature, but high-resolution 3D imaging remains a challenge.

Purpose of the Study:

• To evaluate the performance of the new Skyscan 1272 micro-computed tomography (micro-CT) system for vascular imaging.
• To compare the imaging capabilities of the Skyscan 1272 with the Skyscan 1076 for visualizing vascular networks in hard and soft tissues.

Main Methods:

• Perfusing hard and soft tissues with a barium sulfate contrast agent to highlight the vascular tree.
• Analyzing perfused tissue samples using both the Skyscan 1272 and Skyscan 1076 micro-CT systems.
• Comparing the resolution and clarity of vascular structures visualized by both micro-CT systems.

Main Results:

• The Skyscan 1272 micro-CT system provided significantly clearer and more detailed images of the vasculature compared to the Skyscan 1076.
• The new system successfully visualized a higher number of small vessels that were not discernible with the previous model.
• Improved detection and characterization of the 3D vascular tree were achieved.

Conclusions:

• The Skyscan 1272 represents a significant advancement in micro-CT technology for vascular imaging.
• This enhanced capability offers broader possibilities for assessing vascular tissue engineering strategies by providing detailed 3D vascular network analysis.
• The improved resolution facilitates the detection of fine vascular structures crucial for evaluating tissue development and function.
