A multi-slice double inversion recovery (DIR) pulse sequence with read out
of a signal for imaging successive slices implemented on a magnetic
resonance image scanner. In the method, when the DIR pulse sequence is
applied before imaging each slice, a slab-selective inversion re-inverts
the entire slab that includes all of the slices. All slices are imaged
within a predefined repetition time (TR). The number, N, of slices
acquired per TR controls the inversion time to execute the read out of
the signal for imaging each slice at a zero-crossing point of blood. In a
test, multi-slice DIR images of carotid arteries were obtained with N
ranging from 2-8, for four subjects. The results were compared with those
for both standard single-slice DIR, and inflow saturation techniques.
Multi-slice DIR with N=2-6 provided blood flow suppression in carotid
arteries similar to that of single-slice DIR, and significantly better
than inflow saturation.
