Susceptibility weighted imaging (SWI) allows for
visualization of veins using intrinsic tissue
properties. This technique has gained popularity in the
clinic in the past decade. SWI requires accurate phase
images in order to generate a reliable mask and
ultimately good contrast between veins and adjacent
structures. Multi-channel acquisition therefore requires
a channel combination technique that preserves the
quality of the phase image. We present the application
of the inter-echo variance channel combination technique
for SW imaging and demonstrate single-slice SWI for the
first time.
