一个患有渐进双侧视力损失的儿童的洞穴鼻膜膜瘤最终归因于未被怀疑的视神经外膜膜膜瘤

Begin with a patient with meningioma, or a brain tumor, positioned in an MRI scanner for non-invasive brain imaging.Adjust the scanner to obtain structural images of individual slices of the brain.Enhance the contrast to improve tissue differentiation.Use interslice magnetization transfer ratio imaging on brain slices using radiofrequency pulses slightly offset from the MRI signal.The pulses deliver energy to the proton pool in macromolecules and bound water molecules.This energy transfers to...

Point-of-care ultrasound (POCUS) of the optic nerve sheath diameter (ONSD) has been shown to be useful in identifying patients with increased intracranial pressure (ICP). However, the non-standardized technique for this POCUS has hampered its use. We present a standardized image acquisition protocol for use in the acute care...

This study describes a simplified surgical procedure and technique for performing cavernous nerve stimulation with the isolation of the nerve-electrode complex using silicone glue and intracavernous pressure...

This video demonstrates the isolation and stimulation of the cavernous nerve in an anesthetized rat to study blood pressure changes in the cavernous...

This protocol describes a unique technique using a transconjunctival approach to access the rat optic nerve for injections.

Optic Nerve transection is a widely used model of adult CNS injury. Ninety percent of retinal ganglion cells (RGCs) whose axons are completely transected (axotomy) die within 14 days after axotomy. This model is easily amenable to experimental manipulations and highly...
