ABSTRACT
Objective To study the correlation between the main parameters and the effect of repression in MR fluid attenuated inversion recovery(FLAIR).Methods 0.5 unit was used in this experiment.The protein aqua of different material appearance and concentration was prepared.FLAIR was performed using the tube imitative experimented method and with different paramters.The best scan parameters were selected by comparison each other and their relativity was analysed.Results The best technical parametersTR=4000~5000 ms,TE=90~100 ms,TI=1800~2000 ms.Conclusion TI is the key parameter in determining the repression effect,TR and TE only determine the scans time and layer number.FLAIR's repress result is stable,and it can estimate the protein content in the protein aqua.
