Imaging methods refer to a variety of techniques used to visualize and create images of objects, tissues, or structures within the body. These methods allow researchers to obtain detailed information about the internal anatomy and function of living organisms. Common imaging methods include X-ray, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and positron emission tomography (PET). Each imaging method has its own strengths and limitations, and researchers often use a combination of techniques to achieve the most comprehensive understanding of the biological or medical phenomena they are studying.
