| Purpose: Neonatal cranial sonongraphy performed through the mastoid fontanelle
is more useful to evaluate the peripheral structures at the convexity of the cerebral
hemispheres and brainstem rather than that performed through the anterior fontanelle.
The purpose of this study is to demonstrate the anatomy of the extracerebral CSF
space and brainstem and to suggest appropriate scan planes for performing neonatal
cranial sonography through the mastoid fontanelle using MRI and multiplanar reconstruction
programs.
Materials and Methods: A neonate with normal features on ultrasonography and
good image quality on MRI, including the 3D-SPGR axial scans, was selected. We
made the reconstructed MR images corresponding to the sonongraphic planes and
the anatomic models of the neonatal cranial sonographic images by using axial MRI
as the standard reference on the same screen. We demonstrated the sonographic
images at the levels of the body of the caudate nucleus and lentiform nucleus, the
head of the caudate nucleus and thalamus, the third ventricle and midbrain, and the
midbrain and cerebellar vermis on the oblique axial scans. Four oblique coronal
images at the levels of the periventricular white matter, basal ganglia, thalamus and
tentorium were also obtained.
Results: We illustrated the anatomic atlas with including four oblique axial scans
and four oblique coronal scans that corresponded to the neonatal cranial sonographic
images through the mastoid fontanelle.
Conclusion: We objectively analyzed the anatomy of the extracerebral CSF space
and brainstem by using MRI and multiplanar reconstruction programs and we provided
the standardized sonographic scan planes through the mastoid fontanelle. This
study will be very helpful for evaluating the abnormalities of the peripheral structures at
the convexity of the cerebral hemispheres and brainstem. |
