| Abstract: | In-vivo proton magnetic resonance imaging and relaxation time measurements were carried out on raw and cooked eggs. The relaxation time measurements revealed several interesting results. While there was very little change in the T1 values between the raw and cooked egg white, the T2 values followed the decreasing trend expected of water becoming bound. However, both the CH2 and CH3 moieties of the yolk lipids registered a statistically significant increase in their relaxation times. The T2 of the CH2 group, in particular, increased by 113% in the cooked egg. No striking changes, however, were observed between the proton images of the raw and cooked eggs. |
