Summary
Small animal magnetic resonance microscopy (MRM) offers advanced noninvasive imaging for biomedical research. This technique provides detailed anatomical and functional insights into living animals, aiding in disease and therapy studies.
Area of Science:
- Biomedical Imaging
- Preclinical Research
- Advanced Microscopy
Background:
- Small animal magnetic resonance microscopy (MRM) has transitioned from physics research to a vital tool in biomedical investigations.
- MRM provides functional insights into living animals, imaging organs like the heart, lung, and brain.
- Unlike clinical MRI focused on diagnosis, MRM reveals fundamental biology and subtle organ changes.
Purpose of the Study:
- To review the state-of-the-art in small animal MRM for researchers.
- To cover MR concepts, animal handling, and MRM applications.
- To highlight MRM's potential in tracking biological changes over time.
Main Methods:
- High-resolution anatomical imaging routinely achieves 100 µm in all dimensions in living animals.
- Sub-10 µm resolution is feasible in fixed specimens, approaching conventional histology.
- Interactive viewing in any plane is possible, enhancing data interpretation.
Main Results:
- MRM routinely provides high-resolution anatomical and functional data in living small animals.
- Detailed architectural aberrations in genetically altered models are discernible.
- Tracking of anatomical and functional changes over time is achievable.
Conclusions:
- Small animal MRM is a powerful, noninvasive platform for biomedical research.
- Its ability to provide detailed, dynamic insights makes it suitable for studying disease progression and therapeutic responses.
- MRM is a promising tool with broad applications in preclinical studies, including MR histology.
