The goal of this protocol is to obtain high-quality diffusion weighted magnetic resonance imaging (DWI) of the rat spinal cord for noninvasive characterization of tissue microstructure. This protocol describes optimizations of the MRI sequence, radiofrequency coil, and analysis methods to enable DWI images free from artifacts.

Source: Gouder, et. al. Three-dimensional Quantification of Dendritic Spines from Pyramidal Neurons Derived from Human Induced Pluripotent Stem Cells. J. Vis. Exp. (2015).This video demonstrates the imaging and analysis of dendritic spines in transduced, immunolabeled pyramidal neurons using confocal microscopy. Background noise is reduced, and dendrites are traced by estimating their diameter and length. Automated spine segmentation involves setting parameters for dendrite and spine dimensions...
FAQs
These structures divide mechanical demands across the neck. Intervertebral discs and facet joints help guide motion between adjacent vertebrae, while ligaments and muscles limit excessive movement and maintain alignment. Their coordinated action allows flexion, extension, rotation, and lateral bending without sacrificing the stability needed to support the head or protect the spinal cord.
Controlled movement balances mobility with protection. The cervical spine must permit several directions of neck motion while keeping vertebral relationships stable and preserving the space that contains the spinal cord. When this balance is disrupted by trauma or degenerative change, clinical assessment can help determine whether movement, stability, nerve function, or spinal cord function has been affected.
Cervical radiculopathy and myelopathy represent different clinical concerns. Radiculopathy involves compression or irritation affecting a nerve root, whereas myelopathy reflects dysfunction of the spinal cord. Distinguishing them requires integrating the patient’s symptoms with neurological examination, imaging, and functional evaluation, because the involved neural structure influences diagnostic interpretation and subsequent treatment planning.
Clinical significance depends on which structures are affected and how their function changes. Trauma may compromise stability, degenerative changes may alter joints or discs, and compression may involve a nerve root or the spinal cord. Evaluators therefore consider structural findings together with neurological status and functional performance rather than relying on a single observation.
Assessment combines imaging, neurological examination, and functional evaluation. Imaging helps examine structural changes, while the neurological examination addresses possible nerve-root compression or spinal cord dysfunction. Functional evaluation considers how the neck performs during movement and activity. Together, these approaches support diagnosis and help clinicians select an appropriate treatment or rehabilitation strategy.
After trauma, evaluation focuses on whether injury has affected stability, movement, neural structures, or the spinal cord. Clinicians use imaging alongside neurological and functional assessment to characterize the problem. This combined approach supports safer clinical decisions by identifying findings that may influence treatment, rehabilitation, injury prevention, or the safety of subsequent procedures.
They are used together when clinicians need to connect structural findings with neurological or functional consequences. Imaging can identify relevant anatomical changes, while examination assesses nerve-root compression or spinal cord dysfunction. This combined evidence is useful for conditions such as cervical radiculopathy, myelopathy, trauma, and degenerative change, and it helps guide treatment planning.
Knowledge of the relationships among vertebrae, discs, facet joints, ligaments, muscles, spinal cord, and nerves helps clinicians interpret findings and plan care. It supports safer procedures by clarifying important structures, guides rehabilitation by relating symptoms to movement and stability, and informs injury prevention by emphasizing controlled motion and protection of neural tissues.
