Research and Application of Non-Invasive Examine Technique in Clinical Diagnosis

Non-invasion examine technique is a fast evolving diagnosis technique in the clinical application, especial diffusion tensor imaging (DTI), functional magnetic resonance imaging (fMRI), electroencephalogram (EEG), and mangnetoencephalography (MEG). This article devotes to review the clinical application of non-invasive examine technique in clinical diagnosis. Firstly the basic theoretical background to DTI is discussed, following the clinical applications of DTI parameters, diffusion tensor imaging fibers tracking (DTI-FT), and DTI combined with fMRI, EEG, MEG are reviewed. Finally, the important role of DTI in clinical diagnosis, and the limitations of DTI are also briefly discussed.
