1.5T and 7.0T MRI for central neurocytoma. T2-weighted axial and post-contrast T1-weighted coronal images from 1.5T brain MRI (A, B) and T2-weighted axial and post-contrast T1-weighted coronal images from 7.0T brain MRI (C, D) in a patient with a central neurocytoma (Patient Number 7 in Table 2). A T2-weighted image from 1.5T brain MRI (A) shows the vascularity of the brain tumor & draining veins on the surface of the tumor located in the central portion of the lateral ventricles. Post-contrast coronal images from 1.5T brain MRI (B) demonstrate an intraventricular enhancing mass lesion mainly located in the left lateral ventricle extending into the right lateral ventricle. In contrast to the 1.5T MRI, T2 axial images from 7.0T brain MRI (C) show a clearer image of the tumor margin between the tumor and its surrounding structures and the interface with the thalamo-caudate nucleus. A post-contrast T1-weighted coronal image from 7.0T brain MRI (D) shows better contrast between the white and gray matter in the cortical brain surface in contrast to the 1.5T brain MRI. However, the flow from the deep draining veins of the internal cerebral veins and both transverse sinuses results in linear artifacts crossing over the midline in the post-contrast T1-weighted coronal images from 7.0T brain MRI. In addition, chemical shift artifacts caused by the interface between the cerebellar hemisphere and petrous bone hampers the signal-to-noise ratio of the post-contrast T1-weighted coronal image from 7T brain MRI.
