Dentures and hearing aids should be removed prior to the procedure. Medical staff will provide you with a secure place to store your belongings. The same does not apply to oral GBCAs, which may require you to stop eating and drinking four or more hours in advance. The radiology staff will advise you if any dietary or medication restrictions apply to your procedure. Many insurance companies will cover at least a portion of the cost but require prior authorization to ensure that it is medically necessary.
The extent of coverage can vary by the insurance plan, so check on copay or coinsurance costs in advance of the procedure and confirm that the radiology unit and radiologist are both in-network providers. If you plan to wear any small jewelry there, you may want to bring a pouch for safekeeping. Let the radiology staff know in advance if you have:. While many of these are MRI-safe, they can potentially interfere with the reading.
Tell the staff if you're pregnant. If you have claustrophobia , let the staff know well in advance. In some cases, you might be abel to take a light sedative. If one is used, you'll need to arrange for someone to drive you home after the procedure. For an MRI with contrast, you'll be working with a technician certified in the administration of intravenous, oral, and intra-articular GBCAs.
Qualified technicians are also allowed to administer sedation, although a nurse may also be on hand to do so. After filling out the necessary paperwork and signing a consent form, you will be led to a changing room to change into a hospital gown if needed.
Prior to the MRI, the technician or nurse will check your weight, height, heart rate, temperature, and blood pressure. The technician will then prepare you for the scan in one of several ways. You may feel a sharp poke and a momentary cold sensation as the GBCA is delivered, but you should otherwise feel little pain. If it hurts, let the technician know. A sedative can also be administered through a portal in the catheter if needed. If the GBCA is oral, you'll be given one or several doses of the agent to drink.
Some are berry-flavored, while others have a sweet, syrupy taste. Some people develop a metallic taste in their mouth or feel the need to go to the bathroom after drinking the solution. This is normal. However, if you feel nauseated or have stomach pain, let the technician know immediately. If the GBCA is delivered intra-articularly, the radiologist may use a topical numbing agent prior to delivering the injection.
In some cases, excess joint fluid may need to be removed via arthrocentesis. During the injection, you may feel pressure or pain along the injection route along with a momentary cold sensation. The injection usually takes around 30 seconds to a minute. For MRIs of the head, a cage-like head brace may be used. Depending on the level of sedation used, breathing, heart rate, blood oxygen, and blood pressure may be tracked during the procedure, especially in children.
You may also be given a pair of noise-reducing headphones through which you can communicate with the technician. The MRI itself can take anywhere from 15 minutes to an hour. To ensure the best quality images, follow the technician's instructions and keep absolutely still until you're told to relax. You may also need to hold your breath during some parts of the scan.
It is not uncommon to feel a little warmth during the scan. You will also need to be prepared to experience a loud noise, which some describe as locomotive-like, as each image is taken.
Newer machines are far quieter, however. If you are unable to hold a position, are cramping, or suddenly feel nauseated, let the technician know. It is not a problem to stop and rest until you are ready to proceed.
Once the technician has completed the requested scans, the images will be reviewed to ensure that all are clear and correctly positioned. In some cases, a part of the scan may need to be repeated. If a sedative was not used, you can usually dress and leave immediately.
The technician or nurse may want to check that you have no ill effects before you are allowed to go. If a sedative was used, you will be taken to a recovery room and monitored until you are able to sit up steadily. Once you are able to stand, someone will need to drive you home. Ideally, that person will stay with you for 24 hours in the event of an unexpected side effect. In most cases, there will be no immediate or lasting effects from an MRI with contrast.
Still, it is important to call your healthcare provider immediately if you have any unusual or severe symptoms, including:. If you're breastfeeding, some healthcare providers will tell you to wait 24 to 48 hours before nursing your baby. MRI with contrast scans are interpreted by a radiologist who will review the findings in context with previous scans and your available medical history.
They'll then issue a radiology report within a few days, which your healthcare provider will review with you. A typical radiology report includes a copy of each individual scan along with notations of any abnormalities seen. Typically, each image will be broadly classified as either:. Specific details will be listed in the impressions section of the report, which your healthcare provider can explain to you. Gadolinium is also generally not given to pregnant women unless truly essential, although the exact risk to the fetus is not clear.
Finally, there has been some recent research that gadolinium can be retained in the brain for several months after an MRI; however, there does not appear to be any negative effect on health.

Gadolinium itself is a metal. Women getting mammograms are only one of many groups of patients who may undergo MRI with contrast on a regular basis. For example, for men with prostate cancer who choose active surveillance, receive an MRI with contrast as an annual check, those with multiple sclerosis, some other cancers and more.
In a July 28, article on MedScape , Emanuel Kanal, MD, a neuroradiologist and director of magnetic resonance services at the University of Pittsburgh, is interviewed.
Despite the reassuring messaging that Calechman found in the brochure, she balked at taking the MRI with contrast. She learned that gadolinium can linger in the brain, skin and bone for years, and that Chuck Norris and his wife, Gena, are suing a slew of drug companies , asserting that Gena developed severe health problems due to gadolinium exposure.
And she discovered that radiologists and other scientists are debating, discussing and researching the safety of an agent once believed to be virtually harmless.
Calechman shared her concerns with me and I went looking for answers. Since then, the heavy metal-based contrast agent has been used to assess more than million patients worldwide , according to the American College of Radiology ACR. The side effects patients are reporting now include joint pain, muscle fatigue and cognitive impairment that can last for years.
The gadolinium used in the dye is anchored to a molecule to create a nontoxic compound. Scientists believed that most of the gadolinium left the body along with the nontoxic compound. But then in , a radiologist in Japan reported finding differences in the brain scans of people who had multiple MRIs.
Tissue and autopsy reports have also confirmed that gadolinium can accumulate in the brain and other organs. The U. Food and Drug Administration added warning labels to the dye about gadolinium retention in No studies have linked gadolinium accumulation to the new side effects patients are reporting. Neuroradiologist Emanuel Kanal at the University of Pittsburgh Medical Center says radiologists still need to better understand how gadolinium accumulation may affect patients.
