## Abstract ## Purpose: To extend susceptibility weighted imaging (SWI) to multiple echoes with an adapted homodyne filtering of phase images for the computation of venograms with improved signal to noise ratio (SNR) and contrast to noise ratio (CNR) and to produce high resolution maps of R~2~\* r

In 2D Fourier imaging the normal Cam-Purcell multiple-echo sequence generally leads to center line and mirror artifacts caused by imperfect rotations by the rf pulses. We describe a method to avoid these distortions using aphase alternating-phase shift (PHAPS) sequence which also allows multiple-sli
