  2. Syringobulbia - Wikipedia

    en.wikipedia.org/wiki/Syringobulbia

    The central canal of the spinal cord may be widened. [1] A fluid-filled lesion forms, known as a syrinx. [1] This can vary in size significantly between patients. [1] Nerve fibres may be compressed where they cross the midline, or in other parts of the spinal cord. [1] Cranial nerves may be affected. [3]

  3. Central canal - Wikipedia

    en.wikipedia.org/wiki/Central_canal

    The central canal (also known as spinal foramen or ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. [1] The central canal lies below and is connected to the ventricular system of the brain , from which it receives cerebrospinal fluid, and shares the same ependymal lining.

    Magnetic resonance imaging alias Nuclear magnetic resonance : high strength (0.15 to 1.5 teslas) [4] are used to excite protons that produce the record results (like CT scan). It can show particular tissues more clearly than CT.; [4] video link: Linear accelerator: used in radiotherapy for cancer: Functional magnetic resonance imaging (fMRI ...

  5. Syrinx (medicine) - Wikipedia

    en.wikipedia.org/wiki/Syrinx_(medicine)

    Cerebrospinal fluid fills the syrinx. Pressure differences along the spine cause the fluid to move within the cyst. Physicians believe that it is this continual movement of fluid that results in cyst growth and further damage to the spinal cord. In the case of syringomyelia, the syrinx can expand and elongate over time, destroying the spinal ...

  6. Syringomyelia - Wikipedia

    en.wikipedia.org/wiki/Syringomyelia

    Excess cerebrospinal fluid in the central canal of the spinal cord is called hydromyelia. This term refers to increased cerebrospinal fluid that is contained within the ependyma of the central canal. When fluid dissects into the surrounding white matter forming a cystic cavity or syrinx, the term syringomyelia is applied. As these conditions ...

  7. Cerebrospinal fluid - Wikipedia

    en.wikipedia.org/wiki/Cerebrospinal_fluid

    From the fourth ventricle, the fluid passes into the subarachnoid space through four openings – the central canal of the spinal cord, the median aperture, and the two lateral apertures. [1] CSF is present within the subarachnoid space, which covers the brain and spinal cord, and stretches below the end of the spinal cord to the sacrum.

    en.wikipedia.org/wiki/Spinal_canal

    Spinal stenosis is a narrowing of the canal which can occur in any region of the spine and can be caused by a number of factors. It may result in cervical myelopathy [4] if the narrowed canal impinges on the spinal cord itself. Spinal canal endoscopy can be used to investigate the epidural space, and is an important spinal diagnostic technique ...

  9. Tomography - Wikipedia

    en.wikipedia.org/wiki/Tomography

    A device used in tomography is called a tomograph, while the image produced is a tomogram. In many cases, the production of these images is based on the mathematical procedure tomographic reconstruction , such as X-ray computed tomography technically being produced from multiple projectional radiographs .
