The Advanced Imaging Research Center (AIRC) focuses its research on magnetic resonance imaging (MRI), which is one of the most important clinical imaging modalities. MRI can non-invasively provide exquisite high-resolution images of the brain and soft tissues throughout the body. It also delivers quantitative information about many different tissue properties. NMR spectroscopy of tissue samples and body liquids complements in vivo human and preclinical MRI. Researchers of AIRC also combine MRI with complementary imaging technologies including positron emission tomography (PET), near infrared spectroscopy (NIRS), fluoroscopy, optical imaging, and electrophysiology.
