Brain Tumor Clinical Trial
Official title:
Brain Diseases on 7.0T Magnetic Resonance Imaging
This clinical trial studies the use of 7-Tesla (7T)and 3T magnetic resonance imaging (MRI) in detecting brain diseases. 7T MRI has increased detection sensitivity, including more accurate lesion delineation, higher inter-rater agreement. Diagnostic procedures such as 7T MRI may help ultimately improved diagnostic and therapies confidence to inform decision making than standard 3T MRI.

Primary | the correspondence between brain tumor cells found in the biopsies and region of interest(ROI) signal intension on the 7T MRI scan and 3T MRI scan | Pathological assessment of biopsy material compared with the lesion's contrast-enhancement signal intension to normal brain white mater on 7T MRI and 3T MRI | within a month after biopsy | |
Primary | The visibility of white matter tracts on 7T MRI | Visualization of white matter tracts will be done with the use of diffusion tensor imaging (DTI) on 7T MRI and measuring the mean diffusivity (MD) value on Post-processing workstation ,and analysis the correlation between these values and pathological. | within a month after biopsy | |
Secondary | The correlation between the ROI's signal intension on 7T MRI scan and the KPS in 1 month after operation | The correlation analysis between the T1 contrast-enchanced signal intension, Regional cerebral blood flow on 7T MRI (clinical sequence and perfusion) scan and the KPS in 1 month after operation | within a month after biopsy | |
Secondary | The visibility of white matter tracts on 7T MRI and 3T MRI | Visualization of white matter tracts will be done with the use of diffusion tensor imaging (DTI) on 7T MRI and 3T MRI. and analysis the difference of the mean diffusivity (MD) value between 7.0T MRI and 3.0T MRI | Six months after the biopsy |
