DWI was the trace imaging of three orthogonal directions with b values of 100, 500 and 800s/mm~2, and DTI was in 6 direction with b values of 100 and 800s/mm~2. ADCs, FA and RA values were measured from ADC map and DTI map.

 
  • DTI为6个方向,b值取800s/mm~2,工作站自动合成ADC图及DTI图,手工测量相应ADC值及FA、RA值。 利于扩散加权纤维成像(Diffusion Tensor Tractography,DTT)技术绘制
