Physicians now use magnetic resonance imaging (MRI) to diagnose syringomyelia. The MRI radiographer takes images of body anatomy, such as the brain and spinal cord, in vivid detail. This test will show the syrinx in the spine or any other conditions, such as the presence of a tumor. MRI is safe, painless, and informative and has greatly ...
A syrinx is suggested by an unexplained central cord syndrome or other characteristic neurologic deficits, particularly pain and temperature sensory deficits in a capelike distribution. MRI of the entire spinal cord and brain is done. Administration of intravenous Gadolinium during the MRI examination is useful for detecting any associated tumor.
Diagnosis is made through a combination of patient history, neurological examination, and medical imaging. [23] [24] Magnetic resonance imaging (MRI) is considered the preferred imaging modality for Chiari malformation. [25] The MRI visualizes neural tissue such as the cerebellar tonsils and spinal cord as well as bone and other soft tissues.
MRI imaging appears to be the gold standard for diagnosing a tethered cord. [16] [17] A tethered cord is often diagnosed as a "low conus". The conus medullaris (or lower termination of the spinal cord) normally terminates at or above the L1-2 disk space (where L1 is the first, or topmost lumbar vertebra). After about 3 months of age, a conus ...
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] Syringobulbia may be associated with syringomyelia, a syrinx limited to the spinal cord. [4]
Chiari-like malformation (CM) the most common cause of foramen magnum obstruction and syringomyelia in dogs. Syringomyelia (SM) is a disease of the spinal cord typified by fluid filled cavities, or syrinxes, within the spinal cord substance but it can cause pain by disrupting the cerebrospinal fluid (CSF), in the brain [1] CM is a condition characterized by the mismatch of size between the ...

Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15] MRI can be made sensitive to the motion of molecules.
