Neuroradiologic Investigation of the Visual System Using Magnetic Resonance Imaging

Fast and Quantitative High-Resolution Magnetic Resonance Imaging of the Optic Nerve at 3.0 Tesla

“…Quantified Diameters of ON and CSF Sheath During Straight Gaze (0°) and 30°A bduction mean values 1,2,4,[13][14][15]17,18,24,25. Diameters between 1.9 mm and 3.5 mm (ON) and between 2.9 mm and 4.4 mm (CSF sheath) can be found in literature, which are similar to the results given in…”

“…8,[15][16][17][18] Such techniques are highly sensitive to motion of the eyes that can considerably degrade the accuracy of measurement due to loss of spatial resolution or make it even impossible due to motion artifacts. Thus, these sequences may be sufficient for morphologic imaging, but for quantification a rapid MRI technique that can accurately quantify the ON and CSF sheath diameter within 1.5 seconds was developed.…”

Lateral geniculate atrophy in Parkinson's with visual hallucination: A trans‐synaptic degeneration?

“…The obex is the most caudal point in the fourth ventricle at the medullary level, where ventricle narrows to become the central canal of the spinal cord. The LGN is consistently found in the coronal cut of the brain passing through the PC and obex, oriented according to the PC/obex plane . The LGN borders were delineated on the coronal section, starting with the slice in the PC/obex reference plane and the planes anterior and posterior to the reference one.…”

An Investigation of Lateral Geniculate Nucleus Volume in Patients With Primary Open-Angle Glaucoma Using 7 Tesla Magnetic Resonance Imaging

“…1) 26,44,45 : It was located above the hippocampus and the ambient cistern, beneath and lateral to the thalamus, and medial to the optic radiations. All subjects' MRI data were submitted to a neurologist (YK) to rule other pathologies that are known to present as glaucoma.…”
