Robust retrobulbar MRA using BORR pulse for fat suppression

MR angiography for retrobulbar ocular vessels has been limited due to the fact that the vessels are buried in the excessive fatty tissues around the optical nerves, which has short T1 and long T2 to show high signals in most MR images, and thus the vessel-tissue contrast are low. We proposed using a newly developed technique, namely Binomial Off-resonant Rectangular (BORR) pulse, to completely suppress the fat signal. Compared to other MRA techniques, the BORR method yielded the best angiography contrast, and has the potential to be used on very high fields due to the fast scanning speed and low SAR level.
