We characterized the multi-component transverse
relaxation (T2) decay in egg yolk with high-SNR,
high-quality Carr-Purcell-Meiboom-Gill (CPMG) sequences.
Three T2 components are identified; two fast-decaying
(12 and 23ms) of roughly equal proportion, associated
with water and lipids. The third is a small (2%) slow
component (293ms). The egg yolk is a widely available
phantom material that may prove useful in validating
methods to extract information from short T2 species
like brain myelin-associated water (MAW).
