Molecular Imaging: Advantages and Challenges in Biomedical Research and Clinical Practice

Molecular imaging technology has played an important role in biomedical research and clinical practice due to its visualization advantages. Classic non-invasive imaging methods, such as positron emission tomography (PET), single photon emission computed tomography (SPECT), and magnetic resonance imaging (MRI), often have potential hazards of in vivo radiation, high cost, and difficulty in real-time imaging.
