Molecular Imaging is a medical imaging technique that allows doctors to visualize biological processes at the molecular and cellular levels. It uses advanced imaging technologies, such as PET (Positron Emission Tomography) and MRI (Magnetic Resonance Imaging), to detect specific molecules or cells in the body. This helps in diagnosing diseases, monitoring treatment responses, and understanding disease mechanisms. By providing detailed images of molecular activity, Molecular Imaging enhances the ability to identify conditions like cancer, heart disease, and neurological disorders. It plays a crucial role in personalized medicine, enabling tailored treatment plans based on individual patient needs and biological characteristics.
