Magnetic Resonance Imaging (MRI) Scans during Pregnancy in First Level, First Trimester or with Contrast
This carebox describes MRI scanning in pregnancy, the benefits, risks and alternatives and what to expect when you arrive at hospital.
If you have any other questions, please ask a doctor or nurse looking after you.
What is an MRI scan?
Magnetic resonance imaging (MRI) is a scan that employs strong magnetic fields and radio waves to create detailed images of the interior of the body. An MRI scanner is a short, tube-like device that is open at both ends and holds very powerful magnets. An MRI scan can be employed to scan nearly any area of the body. The findings of an MRI scan can be utilized to assist in diagnosis, treatment planning and evaluating the effectiveness of past treatment.
Is MRI scanning safe during pregnancy?
A great deal of research has been conducted into whether the magnetic fields and radio waves used in MRI scans might be a risk to you or your baby. There is no evidence to indicate there is a risk, which is why MRI scans are among the safest medical interventions used at any point in your pregnancy.
You may not be advised to have an MRI scan in some situations. For instance, if you have a metal implant placed, for instance, a pacemaker or artificial joint, you might not be able to have an MRI scan.
An MRI scan is safe and painless. You might find it uncomfortable if you are claustrophobic but most people can cope with it with the help of the radiographer. Entering the scanner feet first might be more comfortable, although this is not always possible.
We will have you in a special mode, referred to as Normal Operating Mode, on the MRI scanner. This ensures that you and the baby do not become overheated and that the sounds are not too intense for the baby.
Risk Of MRI Scan In Pregnancy
There are times when we cannot utilize the Normal Operating Mode as the quality of the images is not sufficient for your doctor to be able to diagnose your condition or to plan your treatment. Under these circumstances we may have to utilize the ‘First Level Controlled’ mode. This mode is primarily safe and utilized routinely for non-pregnant patients. There is minimal chance of you or your baby getting warm during scanning in this mode and your doctor or the radiographer will therefore talk to you and get your permission first before scanning in this mode.
If you are pregnant in your first trimester there is a theoretical risk of your baby getting warmer during the MRI scan compared to other trimesters. Your doctor or radiographer will therefore talk with you and take consent prior to scanning during the first trimester.
At times you may require an injection of gadolinium based contrast agent (otherwise referred to by brand names Dotarem® and Primovist®), a dye that is used within MRI procedures. If you wish to know more about gadolinium please request a generic information sheet copy. It is not recommended that gadolinium is injected during pregnancy as there is some risk of your baby being harmed. Gadolinium will be used only if your doctor believes that the advantages outweigh the potential for damage. Your doctor will discuss with you and obtain your permission prior to scanning.
Preparation For An MRI Scan
Kindly visit the department wearing comfortable clothing that is free from any metallic zips or buttons if possible. Any jewellery or watches must be removed prior to the scan.
When you get to the department you will be asked to fill out an MRI safety questionnaire. This will request information regarding any surgery or implants in your body and is to check that it is okay for you to enter the MRI scanner. A radiographer will explain this questionnaire to you.
What Does An MRI Scan Involve?
When you have an MRI scan, you will be required to lie on the scanner table that will be pushed up and into the scanner. Depending on what area of your body is being scanned, you’ll be placed into the scanner feet first or head first. Various equipment will be draped over the body part that is being scanned, which will be used to create the pictures. It is extremely essential to be as still as possible when having an MRI scan.
The MRI scanner is extremely loud and you will be provided with ear protection in the form of earplugs or headphones. You will also be provided with a buzzer to hold in which you can use to talk to the radiographer if necessary during the scan. The 15 to 90-minute scan time will be dependent on the size of the area scanned and the number of images.
What Happens After Having An MRI Scan?
After the scan has been completed you can leave the department and go back home. You can eat and drink as usual and resume your daily activities. The scan will be thoroughly examined and reported by the radiologist and sent to the referring doctor who referred you for the scan. It could take up to two weeks to receive the report.
