Although
DW-EPI offers high acquisition speed, it generally suffers from low spatial
resolution and geometric distortion. SSFP is a possible alternative to
perform diffusion imaging with higher resolution and with no distortion
artifacts that is inherent in EPI. In this study, we modified the balanced
SSFP sequence by adding a pair of bipolar diffusion sensitizing gradients.
The diffusion effect in bSSFP sequence with a pair of bipolar diffusion
gradients was formulated and DW-bSSFP experiment was performed on in vivo rat
brain at 7T.
