3D black blood T2w MRI altases of congenital aortic arch anomalies and normal fetal heart

Fetal heart T2w MRI atlases were cretated from MRI datasets acquired at St. Thomas’s Hospital (iFIND project) and clinical fetal CMR service (Lloyd, Lancet 2019), (Lloyd, Circ Cardiovasc Imaging 2021) at Evelina London Children’s Hospital.

• the T2w 3D isotropic images used for generation of the atlases were reconstructed using automated DSVR method (Uus, TMI 2020), (Uus, MedIA 2022) in SVRTK toobox
• the cohorts include 29 fetuses without reported anomalies (“normal”) and 58 cases with postnatally confirmed anomaly: 20 coartaction of the aorta(CoA), 21 right aortic arch (RAA) and 17 double aortic arch (DAA)
• the normal, CoA, DAA and RAA heart atlases were constructed using MIRTK toolbox based on (Schuh, STIA MICCAI 2014) (17 - 29 DSVR images per atlas)
• the correct anatomy was confirmed by a clinician with more than 4 years experience in fetal CMR
• each of the atlases also contain multi-label parcellations of the major cardiovascular structures

3D T2w MRI altas of fetal body

The fetal body atlas was created from 3D DSVR-reconstructed images of 17 normal fetuses (3T, TE=180ms). The parcellation map includes 10 organ ROIs relevant to volumetric studies.

3D T2w MRI altas of fetal head

The fetal body atlas was created from 3D SVR-reconstructed images of 12 normal fetuses (1.5T, TE=80ms). The parcellation label includes the major craniofacial features. Publication is coming soon!
