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).
