In arbitrary units (arbitrary).
The contrast of these images is mainly determined by spatial variations in
the spin density (1H) of the imaged specimen.
In spin-echo sequences this contrast is achieved at short repetition and long
echo times.
In a gradient-echo acquisition, PD weighting dominates the contrast at long
repetition and short echo times, and at small flip angles.
This contrast is achieved at short echo times and long repetition times;
for gradient echo, this weighting is also possible with a short TR (TR<<T1) and a small flip angle.
