A myelogram is a specialized spinal imaging procedure that combines a contrast dye injection with CT scanning to give doctors a detailed look at the spinal canal and nerve roots. Most CT myelogram appointments take 60 to 90 minutes, but patients should plan accordingly when accounting for check-in and a brief recovery period.
In this guide, you’ll learn what a myelogram is, what to expect during the procedure and how long recovery takes. Knowing what to expect can help you feel more prepared, and American Health Imaging can help you get clear answers about your spinal health.
What Is a Myelogram?
Myelography is a diagnostic imaging technique that uses contrast dye injected into the cerebrospinal fluid surrounding the spinal cord. Once the dye is in place, it flows through the spinal canal and highlights structures that may not show up clearly on a standard X-ray.
When doctors refer to a myelogram today, they’re almost always talking about a CT myelogram. A CT myelogram pairs the contrast injection with computed tomography (CT) scanning to produce detailed, cross-sectional images of the spine. This combination gives your doctor a precise view of the spinal cord, nerve roots and surrounding soft tissues, making it one of the most thorough tools available for evaluating complex spinal conditions.
How Long Does a CT Myelogram Take?
From start to finish, a CT myelogram typically takes 60 to 90 minutes. Be sure to plan accordingly to allow time for check-in, preparation and a brief post-procedure observation period.
Here is a general breakdown of how long each part of the myelography procedure may take:
- Check-in and preparation: 10 to 15 minutes
- Contrast injection with real-time X-ray guidance: 15 to 20 minutes
- CT imaging: 10 to 20 minutes
- Post-procedure observation: 15 to 30 minutes
The team at American Health Imaging works efficiently to keep the process as comfortable and streamlined as possible. Many of our locations allow patients to listen to music during their imaging, and our technologists will communicate with you throughout the entire process, giving you the ability to talk back to them every step of the way.
What Happens During a Myelogram?
Before your myelogram, the care team cleans the injection area and uses numbing medication to help you stay comfortable. A contrast dye is injected into the spinal fluid space around your spinal cord. You may feel mild pressure during the injection, along with a brief warm sensation or metallic taste, both of which usually pass quickly.
Your imaging team may gently tilt the table to help the contrast dye move through the spinal canal. You’ll then move to the CT scanner, which takes detailed images of your spine. Your imaging team will stay with you throughout the process, explain each step and monitor you closely.
How Long Does It Take To Recover From a CT Myelogram?
Right after the myelogram procedure, your care team will observe you for 15 to 30 minutes before they clear you to go home. If you’re given a sedative, you’ll need a friend or family member to drive you.
Most patients recover from a myelogram within 24 to 48 hours. For the first 24 hours, plan to rest with your head elevated, drink plenty of fluids and avoid heavy lifting or strenuous activity.
Having a mild headache is the most common side effect and typically resolves within a day or two. Contact your doctor if you develop a fever, stiff neck, persistent headache or numbness in the legs, as these may need prompt attention.
What Conditions Can Be Diagnosed With a Myelogram?
A myelogram gives your doctor detailed information about the spinal canal and nerve roots that other imaging tests may not fully capture. It is commonly used to evaluate and diagnose:
- Herniated or bulging spinal discs
- Spinal stenosis (narrowing of the spinal canal)
- Nerve root compression or impingement
- Bone spurs affecting nerves
- Spinal tumors, cysts or infections
- Complications following spine surgery
- Cerebrospinal fluid leaks
Getting the answers you need about what is causing your symptoms is the first step toward the right treatment plan.
When Does a CT Myelogram Provide More Detail Than an MRI?
Both an MRI and a myelogram are advanced tools for spinal imaging, but they help doctors see the spine in different ways. MRI provides detailed views of soft tissues, while a myelogram is uniquely positioned to show the spinal canal, nerve roots and areas where pressure may be affecting nearby nerves.
A myelogram also produces sharper images for patients with metal implants or spinal hardware that can distort MRI results. When you and your doctor need a more detailed look at your spinal canal and nerve roots, a myelogram helps provide the clarity needed to plan the next step in your care.
