There exists a variety of inconsistent definitions of TE for short echo time sequences throughout the literature. We investigate via theoretical analysis, Bloch simulations, and phantom experiments an appropriate definition of TE for short echo time FID sequences. Erroneous definitions of TE will underestimate the amount of T2 decay and off-resonance phase evolutions, which may result in errors in assessing T2 and/or resonance frequency of tissues.
