What is the purpose of performing a CT scan following myelography?

A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography (CT) to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.

What is the difference between a CT and a CT myelogram?

A computed tomography (CT) scan is frequently performed immediately following the conclusion of the myelography while contrast material is still present within the spinal canal. This combination of imaging studies is known as CT myelography. A myelography examination is usually completed within 30 to 60 minutes.

What are the side effects of a CT myelogram?

What happens after a myelogram?

  • Numbness and tingling of the legs.
  • Blood or other drainage from the injection site.
  • Pain at or near the injection site.
  • Nausea or vomiting.
  • Inability to urinate.
  • Fever.
  • Stiff neck.
  • Leg numbness.

What is CT Cisternography?

Computed tomography (CT) cisternography is an imaging technique used to diagnose CSF rhinorrhea or CSF otorrhea (CSF leaks), as CT allows the assessment of the bones of the base of the skull.

What is a CT scan and what does it do?

A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan images provide more-detailed information than plain X-rays do.

How painful is a myelogram?

How does it feel? You will feel a quick sting from a small needle that has medicine to numb the skin on your back. You will also feel some pressure as the long, thin spinal needle is put into your spinal canal. You may feel a quick, sharp pain down your buttock or leg when the needle is moved in your spine.

How painful is a CT myelogram?

Some patients report discomfort during the injection of the dye; others do not. The CT scan is not painful.

How long does it take to recover from a CT 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.

Is a CT Cisternogram painful?

What will I feel, will it hurt? You may feel a slight stinging sensation when the doctor numbs the skin where the spinal needle will be placed. You will feel some pressure as the spinal needle is placed into the spinal canal.

Can a CT scan detect a CSF leak?

CT myelography is used in the detection of spinal CSF leak. Slow CSF leaks may be detected by postmyelogram CT scan in which there is a time delay between the contrast medium intrathecal injection in the fluoroscopic room and subsequent transfer to the CT scan room.

What are the disadvantages of myelography in dogs?

Disadvantages 1. According to Penderis, et al.(1999), sub dural injection is most common complication observed during cisternal injection of contrast medium. 2. Post-procedural seizures 3. Slight risk of needle puncture into medulla oblongataor cervical spinal cord (Kishimoto, et al., 2003).

How are CT scans used to diagnose dogs?

X-rays are taken from multiple angles as the dog’s body passes through the machine. A full-body CT scan may be performed, or one body part might be focused on alone. Once all of the images are gathered, the dog can wake up, and a radiologist can use the computer to manipulate the images and use them to make a diagnosis.

When to use me-dia and myelography in dogs?

Myelography is indicated when focal spinal cord lesion is suspected and no inflammatory re- sponse is seen on CSF analysis. The contrast me- dia mixes with CSF that surrounds the spinal cord and demonstrates focal spinal cord compression or expansion.

How is radiography used to diagnose spinal injury in dogs?

Prompt and accurate diagnosis is the foremost requirement for treating spinal trauma in dogs. Radiography is one of the most important diagnostic aids for localization of spinal injuries. Plain radiography, though, reveals fractures and luxations in spine, yet, usually fail to suggest any compression (Horlein, 1978) and other soft tissue disorders.

What are the disadvantages of lumbar myelography in dogs?

Disadvantages 1. Technically it is more difficult than cisternal myelography (McCartney, 1997). 2. Kishimoto, et al.(2003) reported various side effects of lumbar myelography as spinal cord edema, cystic necrosis, myelomalacia, axonal necrosis and hydromelia. C) Lumbosacral Myelography: Advantages 1.

X-rays are taken from multiple angles as the dog’s body passes through the machine. A full-body CT scan may be performed, or one body part might be focused on alone. Once all of the images are gathered, the dog can wake up, and a radiologist can use the computer to manipulate the images and use them to make a diagnosis.

How much contrast to use for myelography in dogs?

3. Contrast filling of spinal column is observed to be dose dependent. 4. Concentration of these dyes at 300-350 mg I2/ml is commonly chosen. Recommended volumes of contrast media for myelography in dogs are generally accepted to be 0.3-0.4 ml/kg.

Myelography is indicated when focal spinal cord lesion is suspected and no inflammatory re- sponse is seen on CSF analysis. The contrast me- dia mixes with CSF that surrounds the spinal cord and demonstrates focal spinal cord compression or expansion.
