Facing a medical procedure can often feel daunting, and if you've been advised to undergo an MRI (Magnetic Resonance Imaging), you might be wondering what’s involved.

Knowing what to expect can make a world of difference in reducing any anxiety or uncertainty. From identifying muscle injuries to diagnosing neurological conditions, MRIs play an essential role in helping doctors get a clear picture of what’s going on inside your body.

However, the unfamiliarity of the process can leave many wondering about everything from preparation to what actually happens during the scan.

From before the scan to what you can expect during the procedure and the aftercare, Mykare Health ensures you feel well-prepared, informed, and ready for a smooth experience.

What is an MRI?

Before diving into the specifics of preparation, it’s important to understand what an MRI is and how it works.

MRI uses a strong magnetic field and radiofrequency waves to create detailed images of the inside of the body. This makes it ideal for examining soft tissues, including the brain, spinal cord, muscles, and organs such as the heart, liver, and kidneys.

MRIs are often used to diagnose conditions such as tumors, injuries, inflammation, or diseases affecting the nervous system, among others.

Preparing for an MRI: What to Expect Before the Scan

Preparation is key to ensuring that your MRI scan goes as smoothly as possible. Here are the important steps you need to take before the procedure.

A. Consultation and Medical History

Before scheduling your MRI, you will typically have a consultation with your doctor. This allows your healthcare provider to determine whether an MRI is necessary and to decide on the best type of scan based on your medical needs.

You will be asked to provide a detailed medical history, including any past surgeries, current health conditions, allergies, or medications you are taking.

It’s essential to provide accurate information to help your healthcare provider assess whether there are any contraindications for the MRI, such as the presence of metal implants.

B. Screening for Metal Objects

MRI machines generate very strong magnetic fields, so any metal objects in or on your body can be a significant safety concern. Before your MRI scan, you will be asked to remove all metal objects, including: Jewelry (earrings, necklaces, rings), Watches, Hairpins,Belt buckles,Glasses or contact lenses, Hearing aids, Any clothing or accessories with metal components

In some cases, people with certain types of metal implants or devices (e.g., pacemakers, artificial joints, stents, or shrapnel) may not be eligible for an MRI. It’s crucial that you inform your doctor or MRI technician if you have any such implants, as they may require alternative imaging techniques or special precautions during the scan.

C. What to Wear

MRI scans typically require you to change into a hospital gown to ensure that you are not wearing any metal or clothing that might interfere with the images.

Some imaging centers provide the gown, while others may ask you to wear loose-fitting clothing without zippers, buttons, or any metallic elements. If you need to wear the gown, make sure to dress comfortably and bring an extra layer of clothing for warmth, as the MRI room can sometimes be chilly.

D. Eating and Drinking Before the MRI

For most MRIs, there are no specific dietary restrictions. However, if your scan is related to a specific part of the body, such as the abdomen or pelvis, your doctor may advise you to fast for a few hours beforehand.

Fasting may also be required if you are undergoing a contrast-enhanced MRI, which uses a special dye (contrast agent) to highlight certain areas in your body. Contrast agents may be injected into a vein before or during the procedure. Always follow the instructions given by your doctor or the MRI facility.

E. Taking Medications

In general, you should continue to take your medications as prescribed unless advised otherwise by your healthcare provider. If you are anxious about the procedure, your doctor may offer sedatives or anti-anxiety medication to help you relax.

Make sure to inform the MRI technician or radiologist about any medications you are taking, as certain drugs can interfere with the imaging process.

F. Discussing Claustrophobia

A common concern for many MRI patients is claustrophobia, or the fear of being in tight or enclosed spaces. MRI machines are narrow, and some people may feel uncomfortable or anxious during the procedure.

If you have a history of claustrophobia, it is important to let the MRI technician know before the scan. In many cases, the technician may offer calming techniques or even administer a mild sedative to help you stay relaxed.

What Happens During the MRI: What to Expect

The actual process of undergoing an MRI can vary depending on the area being scanned and the type of MRI used. However, the general experience tends to be similar across different types of scans.

A. Positioning for the Scan

When you arrive at the MRI center, a technician (radiologic technologist) will guide you to the MRI machine and explain what will happen during the procedure. You may be asked to lie down on a table that will slide into the MRI machine, which resembles a large, tunnel-like cylinder.

Depending on the area being imaged, you may need to lie on your back, stomach, or side. In some cases, padding or straps may be used to help keep you still during the scan.

B. The MRI Machine Sounds

One of the most common aspects of the MRI experience that surprises patients is the noise. MRI machines make loud, repetitive sounds, such as knocking, thumping, and buzzing, during the scan. These sounds are caused by the magnetic field and radio waves used to create the images.

While the noise can be startling, the technician will typically provide earplugs or headphones to help reduce the sound. If you’re feeling particularly anxious, you may be allowed to listen to music during the scan as well.

C. Remaining Still

It is crucial that you remain as still as possible during the MRI to ensure that the images are clear and accurate. Even slight movements can blur the images and require the scan to be repeated.

The MRI technician will instruct you to hold your breath or remain still for brief periods, especially if the scan involves the chest or abdomen. If you have trouble staying still, a sedative may be offered.

D. Duration of the Scan

MRI scans typically last between 30 to 60 minutes, but the exact duration can vary based on the type of scan and the area being imaged. In some cases, longer scans may be necessary.

You will be able to communicate with the technician throughout the procedure via an intercom, so if you feel uncomfortable or need assistance, don’t hesitate to speak up.

What to Expect After the MRI: Post-Scan Care

After the MRI scan is complete, you can generally resume your normal activities right away. However, there are a few things you should know about the post-scan process

Once the MRI is completed, the images are sent to a radiologist, a medical professional who specializes in interpreting medical images. The radiologist will review the images and prepare a report for your doctor, who will then discuss the results with you.

Depending on the complexity of the images, it may take a few days for your doctor to receive the report and schedule a follow-up appointment.

Depending on the results of the MRI, your doctor may recommend further tests, treatments, or lifestyle changes based on the findings. In some cases, an MRI may be part of a broader diagnostic process, and additional imaging or medical tests may be needed to confirm a diagnosis or plan treatment.
