A quantitative study on the growth patterns of vertebrae in utero fetuses in second-third trimester：a prospective study based “black-bone” MRI

Imaging the anatomy of the spine and its relevant pathology is clinically important for the early identification of spinal malformations and anomalous osseous development. our study applied MRI-based “black-bone” sequence to elucidate the growth dynamics of vertebrae ossification center in utero fetuses in second-third trimester. We found that the fetal vertebrae were correlated with gestational age and follow a certain formula, providing the existing literature with completely novel quantitative data.
