Fig. 3.

Simulation of the lactate methyl signal S(τ₁, τ₂, φ) acquired with the DQF sequence (see Fig. 2) as given in Eq. [1] against τ₁, τ₂ with the muscle fiber orientation φ relative to B₀ as parameter. Note that the peak signal amplitude decreases and the peak moves towards longer echo times (τ₁, τ₂) as the angle φ between muscle fiber orientation and the orientation of the main magnetic field B₀ increases. Contours are plotted for signal levels (a.u.) in steps of 10. Also note the different scale of each graph. For more details see text.
