New methods and strategies in neuroimaging were briefly documented in this article. Magnetic resonance spectroscopy can depict various metabolites and their concentrations in brain parenchyma and even images for some metabolites can be obtained. Functional MRI as well as functional PET is well known as a tool for exploring cerebral functional anatomy. Many amazing results were revealed in the past literature using these novel functional tools. Diffusion weighted images are used for detection of cerebral infarction and tractgraphy. PET can also depict neuro-transmitter imaging in vivo, which is useful for Parkinson's syndrome, dementia and psychiatric diseases. These new modalities will become increasingly significant in neurology, neurosurgery, psychiatry and radiology during this century.
