Both T2 mapping and field mapping can provide rich
clinically-relevant information. During thermal
therapies for example, field maps provide temperature
information through the proton resonance frequency
effect while T2 can reveal tissue damage and edema. In
brain imaging, field maps reveal iron deposits and
bleeding through susceptibility effects while T2 enables
tumor detection and segmentation. Typically, pulse
sequences based on spin echoes are needed for T2 mapping
while gradient echoes are needed for field mapping,
making it difficult to simultaneously acquire both types
of information. A dual-pathway multi-echo pulse sequence
is employed here to generate both T2 and field maps from
the same acquired data.
