Putting the haste back into T2 HASTE- optimising fetal MRI scanning

Motivation: Comprehensive T2W-HASTE exams can be lengthy for fetal participants. We aimed to reduce this time without compromising image-quality. Goal(s): To reduce scan time in fetal MRI by reducing SAR in T2W-HASTE Approach: All fetal brain images were obtained by interleaving the original-HASTE and stretched RF pulse-HASTE, with either TSE or GRE reference lines, and assessed for image quality Results: There was no significant difference in image quality between the original and the stretched pulse HASTE images either TSE or GRE, assessed in Slice-to-Volume Reconstructions and native images. Impact: Reducing TR in T2 HASTE sequences used in fetal MRI by 33%, can increase the number of scans performed clinically or reduce the time in research taken up by acquiring anatomical images.
