এনেস্থেশিয়া
There is usually no anesthesia with this procedure. Your doctor may give you a mild sedative. You may have local anesthetic to reduce the pain of the needle.
পদ্ধতির বর্ণনা
You will lie on your side or face down. Or, you may sit on the edge of a table, leaning forward. You may be given a local anesthetic injection in your back.
Your doctor will insert a needle into the space between your vertebrae. A small amount of fluid will be removed from the spinal canal. Next, the contrast will be injected through the needle. Your doctor will use an imaging procedure called fluoroscopy. This combines an x-ray unit with a camera and a screen.
To take the images, you will be positioned stomach-down on the table. A brace will be against your shoulders. The table will be tipped forward. Next, the doctor will take images of your back. You will hold your breath while the images are taken. You may be asked to turn slightly to one side and then the other.
Often, your doctor will perform a CT scan after myelography. This is to see the spread of the contrast dye.
অবিলম্বে প্রক্রিয়া পরে
You may be asked to stay in the exam room while the doctor looks at the images. You will be able to go home after about an hour.
কতক্ষণ এটা লাগবে?
