Multimodal imaging is an emerging field in medical imaging that involves the combination of multiple imaging modalities to provide a more comprehensive and detailed view of biological tissues or structures. This approach allows for the complementary strengths of different imaging techniques to be combined, providing a more accurate and complete picture of a patient's condition. By combining techniques such as magnetic resonance imaging (MRI), computed tomography (CT), positron emission tomography (PET), and ultrasound, multimodal imaging can provide valuable insight into the structure, function, and metabolic activity of tissues, as well as help in diagnosis, treatment planning, and monitoring of various diseases.
