Test
The spinal canal is usually more than 0.5 in (12 mm) in diameter. A smaller diameter indicates stenosis. The diameter of the cervical spine ranges is 0.6-1 in (15-12 mm). Any opening under 0.5 in (13 mm)in diameter is considered evidence of stenosis.
Central canal stenosis with an anterior-posterior (AP) diameter of 9mm indicates a narrowing of the central spinal canal, which is the space within the spine that houses the spinal cord and nerve roots. An AP diameter of 9mm is generally considered to be below the normal range, potentially leading to compression of the spinal cord or nerves. This condition can result in symptoms such as pain, numbness, or weakness in the extremities, depending on the severity and location of the stenosis. Evaluation by a healthcare professional is recommended for appropriate management.
11-16mm
A normal myelogram would show a spinal canal of normal width, with no areas of constriction or obstruction
A normal myelogram typically shows a smooth and uniform distribution of contrast dye within the spinal canal. There should be no blockages, leaks, or abnormalities in the flow of the dye, indicating a healthy spine and spinal cord. The radiologist will also look for any signs of compression on the nerves or spinal cord.
The central canal of the spinal cord. The central canal, also known as ependymal canal, is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord.
in the spinal canal between the vertebrae.
what is narrowing of the right subarticular zone of the spinal canal
It is thought that syringomyelia occurs when one or more factors interfere with the normal development of the spinal canal during formation of the embryo or when factors such as trauma to the spinal cord.
