Fast spin echo (FSE) imaging plays a central role in
clinical MRI. When combined with flip angle modulation,
very long echo train can be used without excessive
blurring, which makes 3D FSE imaging feasible in
clinical setting. FSE requires CPMG condition. However,
this condition can be violated in a number of
applications due to system imperfection and result in
image artifacts. We recently proposed a non-CPMG FSE
acquisition based on a phase cycling method. However,
this approach doubles scan time. Here we discussed the
methods to reduce the scan time of this approach.
