What are the Common Techniques Used in In Vivo Imaging?
Several techniques are employed in in vivo imaging, each offering unique advantages:
- Magnetic Resonance Imaging (MRI): MRI provides high-resolution images of soft tissues and is excellent for observing structural and functional changes in organs.
- Positron Emission Tomography (PET): PET is used to study metabolic processes by tracking the distribution of radioactive tracers, offering insights into biochemical changes induced by toxicants.
- Computed Tomography (CT): CT scans provide detailed cross-sectional images and are useful for detecting structural changes in tissues exposed to toxins.
- Optical Imaging: This technique involves the use of luminescent or fluorescent probes to visualize molecular and cellular events, offering high sensitivity and specificity.
- Ultrasound Imaging: Ultrasound is a real-time imaging technique that is non-invasive and cost-effective, used to monitor changes in tissue structure and blood flow.
