Application of MR-DTI to Study the Repeatability of Motor Fiber Bundles
Objective To study the quantitative reproducibility of the pyramidal tract using DTI.Methods Two MRI plain scans and DTI were performed on 28 volunteers,one for the first scan and the other two weeks later.Using DSI-studio software,Measure the MD,FA,AD,and RD of four groups of fiber tracts:corticospinal tract,reticular spinal tract,corpus callosum,and superior cerebellar peduncle.Conduct replicable studies on the relevant data of two groups of the same fiber bundle.Statistical methods(ICC)were applied for analysis.Results Four groups of motor related fiber bundles,the correlation coefficient(ICC)between FA,MD,AD,and RD groups is 0.942-0.994.Conclusion The repeatability of two measurements of the same group of fiber bundles is good,and the method is reliable.
