ABSTRACT
PURPOSE: Neonatal cranial sonongraphy through the posterior fontanelle is more useful than through the anterior approach for the evaluation of posterior brain structures. The aims of this study were to determine the appropriate neonatal cranial sonography scan planes through the posterior fontanelle, and to objectively evaluate the anatomy of neonatal cranial sonographic images. MATERIALS AND METHODS: Neonates who underwent cranial sonography and MRI including 3D-SPGR axial scans and showed normal features on both modalities were enrolled. We reconstructed MR images corresponding to sonongraphic planes, then constructed anatomic models of the neonatal cranial sonographic images using axial MRI as the standard reference on the same screen. RESULTS: We successfully created anatomic atlas that represents 8 oblique coronal and 4 oblique sagittal scans and planes that corresponded to the neonatal cranial sonographic images through the posterior fontanelle. CONCLUSION: The objective manner of this anatomic research provided standardized sonographic scan planes and created anatomic model through the posterior fontanelle. Cranial sonographic models through the posterior fontanelle using MRI and multi-planar reconstruction program will be helpful in the evaluation of sonographic anatomy and detection of abnormalities in the basal ganglia, thalamus and posterior part of the brain.
