CRL2025: 193 Fetal MRI T2 Reconstructions (20-38 Weeks Gestation)

193 fetal MRI T2 reconstructions covering gestational ages 20 to 38 weeks, developed by researchers at Boston Children’s Hospital and Harvard Medical School. The data, updated in March 2026, consists of intensity-corrected images registered to atlas space derived from multiple T2-weighted stacks.

Use Cases

• Developing automated segmentation tools for fetal anatomy using T2-weighted reconstructions
• Studying longitudinal fetal development across the 20-38 week gestational age range
• Benchmarking registration algorithms against the provided atlas-space coordinates

Strengths

• 193 individual fetal MRI reconstructions
• Covers a continuous gestational age span from 20 to 38 weeks
• Pre-processed with intensity correction and atlas registration

Limitations

• Small sample size of 193 subjects
• Limited to T2-weighted modality
• Lack of detailed clinical diagnostic labels beyond gestational age
