3D Fast Spin Echo (3DFSE) with flip angle modulation is
used for high resolution T2 weighted imaging due to high
T2 contrast and the ability to reformat the data in any
desirable plane. Unavoidable violations of the CPMG
condition due to system imperfections generate
artifacts. In this work we present a technique to
overcome this problem using a post processing method
applied in conjunction with a two excitations approach.
The drawback of the method is that two excitations are
required. However, in many applications this method is
necessary in order to acquire reliable high quality
images.
