Article Synopsis
- The study aims to analyze the development of costal element ossification centers in the fetal spine using postmortem MRI.
- The research included 71 fetuses, examined using specific imaging techniques and validated through CT and histological analysis of two specimens.
- The findings indicate that S1, S2, and S3 ossification centers appear at different gestational ages, with S1 and S2 being more consistently detectable in later stages, and their volumes increasing significantly with gestational age.
Purpose: To describe the temporal pattern of the appearance of the S1-Co1 centrum ossification centers (COCs) and provide reference data for the S1-S5 COCs and sacral length at various gestational ages (GAs).
Methods: Postmortem magnetic resonance imaging (MRI) was performed on 71 fetuses (GA, 17-42 weeks) using the 3D dual-echo steady-state with water excitation T2 sequence in the sagittal plane. To confirm the reliability of this sequence, the MRI data were compared with the CT and histologic data obtained from two fetuses (GAs, 21 and 30 weeks).
