Optimal conditions for the measurements of
OGSE-EPI diffusion coefficients were assessed with a repeatability study in
healthy mice. Best results were obtained using a 4-channel surface coil and
respiratory gating when measuring ADC at 100 Hz
Table 1 : Repeatability study results. In bold,
the optimal repeatability coefficient.
Figure 1: Examples of resulting ADC maps,
superimposed on magnitude images at b-value = 0 s/mm2. A) using
volume coil, B) using 4-channel parallel coil, C) without respiratory gating,
D) with respiratory gating. Volume coil images have larger sensitivity area
while surface coil images has higher signal magnitudes. Respiratory gating visually
reduces signal artifacts.
