Myelogram Test Prep
What is a Myelogram? Who Performs the Exam? A myelogram is a radiological examination of the spinal cord and the space surrounding it. A contrast medium (commonly called "dye") will be injected into your spinal canal. The contrast medium highlights the area of interest. A radiologist performs the examination. A radiologist is a medical doctor who specializes in the use of x-rays for diagnosis of medical conditions. The radiologist is assisted by a radiological technologist, who is trained in the use of x-ray equipment and by a registered nurse.
Where is the Exam Performed? How Long Does the Exam Take? Myelograms are performed in the Radiology Department of the ground level of our Hospital. Your exam probably will be completed in approximately 2 hours, but may take longer. The recovery period is about 2 hours. Arrange to have someone stay with you for 24 hours following the procedure. Inpatients will return to their rooms to recover. 
What Happens During the Exam? There are various techniques used for administering the contrast medium. The radiologist will identify the best location to insert the needle. First, the area will be cleaned with antiseptic solution, which may feel a little cold. Second, you will feel a pin prick in the skin, and a brief burning sensation as a local anesthetic is injected. The radiologist will insert a needle and inject the contrast medium. The x-ray table will be tilted slowly to allow the contrast medium to travel to different levels of the spinal column. The radiologist will watch the flow of the contrast medium on a TV monitor. Then the technologist will take a series of x-rays while the table is tilted in various positions. The nurse will monitor your vital signs and assess your need for analgesics. You will then be taken to another room where a CT scan of the spine will be performed.

Before Your Exam:

• If you are a smoker, your doctor may ask you to stop smoking the day before your test and on the day of your test. Smoking before the procedure may contribute to headaches or nausea after the procedure.
• It is important to stay well hydrated until the time of your exam. For this reason, we recommend that you drink fluids every 2 hours while you are awake. This regimen may start at noon the day before your test and continue until 6 hours before your exam. You may drink clear liquids up to 2 hours prior to the procedure. Clear liquids are water, tea apple juice, and broth. Orange juice is not a clear liquid.
• If you are taking any of the following drugs, you should stop taking them 2 days before your myelogram and resume taking them 2 days after your myelogram.
• Blood thinners, like Coumadin, need to be stopped prior to your procedure. You must ask your physician for instructions regarding the length of time.
• If you are diabetic and are taking Glucophage, Glucovance or Avandamet you must not take the medication for two days after the procedure. Ask your physician for instructions.
• Allergies: If you are allergic to contrast (X-ray dye) or iodine, let your doctor know as soon as possible. Let the interventional radiologist know about your allergy a few days before your scheduled myelogram.

After The Procedure

• If you are already a patient in the hospital or if you have been scheduled to be admitted to the hospital immediately after your procedure: you will stay in the hospital after your study is completed. You will return from the radiology department to your hospital room, and the nursing staff will observe you to make sure you are all right.
• If you are having your myelogram done as an outpatient: you will stay in the hospital for two hours after the procedure is completed. Hospital staff will watch over you to make sure that you are all right. You will go home after the observation period.
• Please make arrangements for someone to drive you home. You may not drive yourself home. The radiologist will send a report to your doctor after he has studied your x-rays. It is best to ask your doctor for the exam results.

When you go home:

• After the exam, there is usually no need to remove the contrast material from your spinal canal. Myelographic contrast material is absorbed by your body and eliminated naturally through your kidneys by urination within 1-2 days.
• Drink extra fluid - 1 cup every other hour until bedtime - unless otherwise instructed by your doctor.
• Fluids will help eliminate the contrast medium from your body and help prevent headaches.
• Avoid strenuous physical activity that involves bending down.
• To the extent possible, avoid coughing, sneezing, straining and quick movements for 24 - 48 hours.
• You may immediately resume medication and diet as before the examination.
• You will remain in the Radiology Recovery Room for about 2 hours.
• Please have someone accompany you who is able to drive you home. You can not drive yourself home.

You should call your doctor if any of the following conditions should develop

• excessive nausea and/or vomiting
• severe headache
• fever
• stiff neck
