What is the difference between an MRI and a myelogram?

Compared to an MRI, a myelogram, and the post myelogram CT scan, is able to show the bony details in a better way, but is less capable of showing the soft tissue details in your spine.

What abnormality is demonstrated using myelography?

tumors involving the bony spine, meninges, nerve roots or spinal cord. infection involving the bony spine, intervertebral discs, meninges and surrounding soft tissues.

What is the difference between a myelogram and a lumbar puncture?

A myelogram is performed first in a separate procedure. This is similar to a lumbar puncture, or spinal tap, where the fluid space around the spinal cord (within the spinal canal) is accessed with local anesthesia and contrast (usually 12cc non-ionic iodinated contrast) is administered.

What is cervical myelography?

Cervical myelography is obtained after injection of contrast medium into the lumbar subarachnoid space through a lumbar puncture. The patient is prone with a large radiolucent block under the pelvis so that the site of lumbar puncture is at a higher level than that of the cervical spine lordosis.

How long does it take to recover from a myelogram?

The recovery period is about 2 hours. Plan to be in the Department of Radiology for 4-6 hours. Arrange to have someone stay with you for 24 hours following the procedure.

How long does it take to recover from myelogram?

What are side effects of a myelogram?

What happens after a myelogram?

• Numbness and tingling of the legs.

Do you get sedated during a myelogram?

A myelogram is an outpatient procedure that takes about an hour. You will be asked to remove clothing and jewelry that may interfere with the test. You will lie down on a padded table and will receive sedation (medication to make you drowsy and relaxed).

What are the radiographic features of arachnoid cysts?

Radiographic features. Arachnoid cysts can occur anywhere within the central nervous system, most frequently (50-60%) located in the middle cranial fossa, where they invaginate into and widen the sylvian fissure.

Which imaging modalities are used in the workup of arachnoiditis?

All modalities will demonstrate similar findings although MRI is by far the most sensitive modality. Although arachnoiditis can be present throughout the subarachnoid space, it is most easily seen in the lumbar region where the cauda equina usually floats in ample CSF.

What is arachnoid granulation?

Arachnoid granulation. Dr Daniel J Bell ◉ and A.Prof Frank Gaillard ◉ ◈ et al. Arachnoid granulations, also known as Pacchionian granulations, are projections of the arachnoid membrane (villi) into the dural sinuses that allow CSF entrance from the subarachnoid space into the venous system.

What is the pathophysiology of arachnoiditis?

Although arachnoiditis can be present throughout the subarachnoid space, it is most easily seen in the lumbar region where the cauda equina usually floats in ample CSF. As a result of inflammation, the nerve roots become adherent to each other and to the theca.
