Rapid R2 mapping is of significant interests to MRI
scientists and can be applied in many research areas.
The recent introduced SE-SS-PARSE (single-shot parameter
assessment by retrieval from signal encoding) is an
ultrafast and direct R2 mapping technique. By modeling
signal changes during the sampling, SE-SS-PARSE promises
a more accurate and robust data measurement. This study
evaluates the accuracy of R2 mapping in SE-SS-PARSE by
comparing it with fast SE, a commonly used rapid R2
mapping method. Conventional SE provided references. We
found that SE-SS-PARSE provided accurate R2 mapping with
a much shorter acquisition time compared to fast SE.
