A technique to eliminate artifacts in 3D Fast Spin Echo Imaging

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.
