Microvascularization of the human central and peripheral nervous system: A new microcomputed tomography method

Area of Science:

• Medical Imaging
• Anatomy
• Radiology

Background:

• Microcomputed X-ray tomography (microCT) is a miniaturized imaging technique derived from medical tomography.
• It offers distinct vascular imaging capabilities compared to microradiography, particularly in visualizing microvascularization in three dimensions.
• Understanding microvascular networks is crucial in various anatomical and medical research fields.

Purpose of the Study:

• To demonstrate the application of microCT for detailed imaging of microvascularization.
• To highlight the advantages of advanced software in reconstructing and visualizing complex vascular structures.
• To present examples of microCT imaging in different anatomical regions.

Main Methods:

• Anatomical specimens were fixed with formalin and injected with a barium-gelatin mixture.
• Samples were analyzed using microCT, with acquisition times varying based on sample size.
• Projection images were reconstructed into 2D sections and combined for 3D model generation using volume rendering software.

Main Results:

• MicroCT successfully visualized microvascular networks in various anatomical locations, including the inferior alveolar nerve, cerebral cortex, brain stem, and basal ganglia.
• High-end reconstruction software (VGStudio max) effectively highlighted small capillaries, preserving crucial details.
• Conventional or freeware resulted in significant loss of information regarding small vessel visualization.

Conclusions:

• MicroCT provides advanced 3D visualization of microvascularization, surpassing traditional methods in spatial detail.
• The choice of reconstruction software is critical for accurate representation of fine vascular structures.
• VGStudio max facilitates detailed 3D exploration and educational video production for microvascular anatomy.
