open and unobstructed
This means that the openings in the canal and foramina are normal in size, thus there is no restrictions that would cause any nerve problems.
The auditory canal is your inner ear - the part inside your cranium. Patent means open. A widely patent auditory canal would be one that is especially wide/open/large.
It means the canal and foramina are normal in size and allows for nerves to pass through freely without restriction.
It's good news -- no spinal stenosis.
The term "patent neural foramina thecal sac" refers to the openings (neural foramina) in the spine that allow spinal nerves to exit from the spinal canal and the surrounding protective sac (thecal sac) that encases the spinal cord and nerve roots. "Patent" indicates that these openings are unobstructed and open, allowing for normal nerve function. In a clinical context, this phrase is often used in imaging reports to indicate that there are no blockages or abnormalities affecting the passage of nerves in that area.
Vertebral foramen are the spaces between adjacent vertebrae where the spinal nerves exit the spinal canal.
The Neural Foramen are grooves in the vertebra, just behind the vertebral body that the nerves that branch off the spinal cord exit the spinal canal from. If they are grossly patent they are open, and free from obstruction, so there is no compression of the nerves that course through these channels.
The Sacral Canal runs throughout the greater part of the Sacral bone, The four Posterior Sacral Foramina are lateral to the articular processes of the Sacrum and are smaller in size and less regular in form than the anterior.
When the spinal canal is described as "patent," it means that the canal is open and unobstructed, allowing for the normal passage of spinal nerves and cerebrospinal fluid. This indicates that there are no significant blockages or narrowing (stenosis) that could compress the spinal cord or nerves. A patent spinal canal is essential for maintaining proper neurological function and overall spinal health.
The lateral recess is an anatomical space within the spinal canal, located laterally to the spinal cord, where nerve roots exit the spinal column. The neural exit foramina, or intervertebral foramina, are openings between adjacent vertebrae that allow spinal nerves to exit the spinal canal and innervate various parts of the body. These structures are crucial for the proper functioning of the nervous system, as they facilitate the passage of nerve roots to their target tissues. Compression or narrowing of these areas can lead to neurological symptoms or pain.
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.
The central canal of the spinal cord or bone is open and unobstructed, allowing for the passage of cerebrospinal fluid or blood vessels. This ensures proper communication and transport of essential substances in the central nervous system.
