Typical single refocused pulsed-gradient spin-echo (SRSE-DWI) sequence is interacted by susceptibility-induced background gradient fields around vessels, while twice-refocused spin-echo (TRSE-DWI) sequence is reduced the effect. The difference between SRSE-DWI and TRSE-DWI will indicate CBV weighted image. We evaluated the ADC reduced ratio in both sequence with computer simulations in a vascular model. We made TRSE-DWI sequence for animal MRI and evaluated on stroke model rats. The simulation results indicate possible criteria for brain stroke validation. The experimental results did not show adequate S/N images. |
