Whole animal imaging.

Area of Science:

• Biomedical Imaging
• Translational Research
• Animal Models

Background:

• Translational research is crucial for understanding human disease pathophysiology and developing diagnostics/therapeutics.
• Animal disease models are essential for evaluating pathophysiologic changes and therapeutic interventions.
• Current evaluation methods include immunohistologic and imaging techniques.

Purpose of the Study:

• To provide a comprehensive overview of whole animal imaging techniques for translational research.
• To describe the basic principles, contrast mechanisms, applications, challenges, and future prospects of various imaging modalities.
• To serve as a resource for researchers and students in animal research.

Main Methods:

• Review of various whole animal imaging techniques.
• Discussion of noninvasive imaging for longitudinal and dynamic studies.
• Comparison of strengths and weaknesses of different imaging modalities.

Main Results:

• Noninvasive imaging techniques allow for whole-animal evaluation, minimizing experimental variability and animal usage.
• Various techniques like X-ray CT, MRI, PET, SPECT, ultrasound, fluorescence, and bioluminescence imaging offer distinct information.
• Each imaging technique has unique advantages and limitations for specific applications.

Conclusions:

• Whole animal imaging is a powerful noninvasive approach in translational research.
• The choice of imaging technique depends on the specific research question and required information.
• Advancements in imaging technology continue to enhance their utility in preclinical studies.
