The multi-echo SWV with the proposed complex signal modeling method can provide high-SNR and multi-contrast phase masks and SWV images. The multiplication number of the phase mask for SWV was increased up to 16 without image degradation even at the long TE of 49.8 ms. More detailed vein structures were visualized with higher- and multiple contrasts than the conventional single-echo GRE SWV.
