We compared single-echo and a novel multiple-echo image
combination using source or susceptibility weighted
images (SWI) for improvements in image quality assessed
quantitatively through intramyocardial hemorrhage
contrast and signal-difference-to-noise measurements.
SWI with echo-combination was an effective means of
generating high quality images of left ventricular
myocardium for tissue characterization. Echo-combination
of source or SWI images increases SNR at the cost of
hemorrhage contrast. SWI with six phase mask
multiplications and 10 echo averages provides optimal
image SDNR and contrast. Image quality of echo-combined
SWI is superior to source, SWI and echo-combined source
images.
