Synopsis
In the inversion-recovery Look-Locker T1-mapping, the use of slice-selective inversion recovery pulse is explored to map the long T1-values of the spleen with as many slices as possible. The optimal slice gap in combination with interleaving the slices was determined. Artifact-free T1-maps of the spleen were obtained after parameter optimization with double the number of slices than using the standard approach in a single breath-hold. This new approach is an important step towards achieving complete coverage of abdominal organs within a single breath-hold.
