SpIC3D imaging for spinal in situ contrast 3D visualization.

ABSTRACT: High-definition visualization techniques are critical for understanding the neuroanatomy of the spinal cord, an essential structure for sensorimotor and autonomic functions, in both healthy and pathological conditions. Magnetic resonance imaging (MRI) is a common method for visualizing neural structures in 3D. However, techniques for spinal cord MRI have historically achieved limited visualization of rootlets and nerves, especially at lower spinal levels, due to their highly complex and compact organization. Here, we developed a spinal in situ contrast 3D imaging (SpIC3D) method that allows visualization of spinal compartments in fixed animal and human specimens with high resolution (50 μm) at various spinal levels. Using SpIC3D, we achieved quantification of neuronal cell density in dorsa
