In Vivo Imaging refers to techniques used to visualize biological processes within living organisms. This method allows researchers and medical professionals to observe the structure and function of tissues and organs in real-time, providing valuable insights into health and disease. Common imaging modalities include MRI, CT scans, and PET scans, each offering unique advantages for different applications. These imaging techniques are crucial for diagnosing conditions, monitoring treatment responses, and conducting research. By enabling non-invasive observation, In Vivo Imaging helps improve our understanding of complex biological systems and supports the development of new therapies and interventions.
