The effect of DSG prep on blood and vessel wall signal. The two red lines indicate the DIR blood signal at 24 mm (used in 3D mode) and 7.5 mm (used in 2D mode) inversion slab thicknesses. Blood signal (blue) decreases with higher b-value and is comparable to DIR blood signal (red) at 7.5 mm inversion slab thickness when b > 2 s/mm2. Vessel wall signal (black) experiences the expected attenuation due to T2 decay at low b-values, and greater attenuation when b > 10 s/mm2. Arrow on the b-Value axis indicates the optimal sensitization.
