reported T2*quantification for calcium phosphate cement
(CPC), a widely used bone material, remained unsatisfactory with a
mono-exponential (ME) fit. A recently proposed Gaussian augmentation of the mono-exponential
(GAME) model was reported to have robust fit for gradient echo (GRE) signals.
To accurately evaluate GRE-signal decay of CPC, GAME and ME fits were applied
in this study for multi-echo time GRE signals acquired at 11.7T. Compared to
ME, GAME showed optimal fitting with significantly smaller sum of squared errors and larger R-squared values. Therefore, GAME model is
demonstrated to be suitable for GRE signal modeling in CPC at ultra-high field.
