Pixel-wise T2* mapping is an emerging clinical technique
for detection of myocardial iron overload and provides
the benefit of having spatial context between tissues
when compared to ROI-based T2* mapping. However,
pixel-wise mapping is less precise than ROI-based
mapping due to its use of low SNR data. We propose and
validate a tool to estimate error (standard deviation)
maps for evaluating the precision of pixel-wise T2*
mapping techniques. This tool will be useful to
researchers prototyping and developing more precise
pixel-wise mapping techniques.
