PURPOSE: We wanted to objectively evaluate the anatomy of the neonatal brain on ultrasound images, and so we reconstructed several oblique magnetic resonance images that corresponded with the oblique ultrasound images by using MRI and a multiplanar reconstruction program. MATERIALS AND METHODS: MRI 3D-SPGR axial scans of the brain were performed for two neonates and then we obtained the reconstructed MR images that were parallel with the direction of the sonographic oblique scanning plane. We made the anatomic models of the neonatal cranial ultrasound images by using axial MRI as the standard reference on the same screen. RESULTS: We created an anatomic atlas, with the representative six oblique coronal scans and six oblique sagittal scans that corresponded to the neonatal brain ultrasound images. CONCLUSION: This objective anatomic research with using MRI and a multiplanar reconstruction program for creating the ultrasound oblique brain images of a neonate will be very helpful for evaluating the ultrasonographic anatomy and to apply it to clinical practice.
