ABSTRACT
Purpose To explore the significance of three-dimensional reconstruction of fetus based on MRI scan data. Materials and Methods Three woman (more than 39 weeks' gestation) with a strong wish to have natural childbirth and voluntary to take the examination in Nanfang Hospital of Southern Medical University were recruited in the study. Mimics 10.01 software was used to do three-dimensional reconstruction. Results The fetal surface tissue showed low signal on the two-dimensional images, and amniotic fluid and lung, bladder, cerebrospinal fluid showed high signal. The placenta and uterine wall showed moderate to low signal. Those contributed to the clear boundary between fetal surface and other tissue surround. The three-dimensional fetus models were reconstructed successfully, which clearly demonstrated the main surface features and spatial position of the fetus. The fetal morphology and fetal position could be viewed in various directions. Conclusion Fetus surface can be reconstructed into three-dimensional model based on MRI data set, which has advantage of large visual field and can be observed at arbitrary angle. It provides a new method for morphological analysis and prenatal evaluation for fetal development and growth.
