ABSTRACT
Objective:
To discuss the effect of the choice of brain functional MRI parameter on image quality.Methods:
To select nine young volunteers for scanning brain functional MRI from February to December, 2012, and analyze the effect caused by parameters to the image quality.Results:
The lower of the b value, the more level 1 image, the less level 3 image;the more of the number of diffusion sensitive gradient direction, the more level 1 image, the less level 3 image. The largest impact on image quality is the interlayer spacing, the number of diffusion sensitive gradient direction and the b value.Conclusion:
The factors influencing the quality of brain functional MRI images including the interlayer spacing, the number of diffusion sensitive gradient direction and b value. In the parameter selection process, one should start from diagnostic purposes and weigh the pros and cons with overall consideration.
