More specifically, therapeutic strategies including photodynamics, chemotherapy, gene therapy, hyperthermia, and radiation are integrated with one or more diagnostic imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), position emission tomography (PET), single photon emission computed tomography (SPECT), near-infrared (NIR) fluorescence imaging, and ultrasonography to develop molecular diagnostic tests and targeted therapeutics in clinics, resulting in the advance of personalized medicine.
