Magnetic resonance imaging (MRI) is a medical procedure that utilizes a magnetic field and radio waves to create detailed images of the body’s internal organs and tissues. It’s a valuable tool that allows medical professionals to diagnose and monitor a variety of conditions, such as injuries, infections, and tumors. However, there’s often confusion about whether or not patients can eat before the scan. In this article, we’ll explore the importance of MRIs, debunk common myths about fasting before the procedure, and provide tips for patients to prepare for an optimal scan.

Prepping for an MRI: Debunking Common Myths About Eating Before the Scan

It’s common for medical professionals to ask patients to refrain from eating before an MRI scan. The reason for this is to ensure that there’s no food in the stomach that could potentially interfere with the scan. While this may seem like a minor inconvenience, it’s actually an important step in achieving an accurate result.

Some common misconceptions about eating before an MRI scan include the belief that it will help reduce anxiety or that it doesn’t matter what you eat or drink. However, MRI scans are sensitive to motion and different types of tissue, and anything that is in the stomach can create artifacts that look like abnormal tissue. For this reason, it’s crucial that patients follow the no-food rule.

Medical professionals also recommend that patients refrain from smoking, chewing gum, or consuming anything else that could accidentally be swallowed during the procedure. Any foreign object inside the body can alter the MRI results and create artifacts that could mimic abnormalities.

Take Note: Why Eating Before an MRI Could Impact the Results

Consuming specific foods or liquids before an MRI can affect the quality of the scan and lead to inaccurate results. For example, caffeine can increase heart rate and cause patients to feel jittery and anxious, which can make it difficult to remain still during the scan. Sugary foods or beverages can alter blood sugar levels, while high-fat foods can cause the gallbladder to contract and produce artifacts in the images.

Medical professionals advise patients to avoid consuming any food or drinks for at least four hours before the MRI scan. This includes water. The only exception is if the patient needs to take medication that they require with a small sip of water. It’s important to follow the specific instructions given by the doctor or technician regarding prepping for the MRI, including medication use. Consuming food or liquids too close to the appointment time could result in it being cancelled or rescheduled.

Feeding Your Mind and Body: What to Eat Before and After Your MRI

Patients undergoing an MRI need to prioritize their health leading up to the scan. Eating a nutritious diet can help improve the overall well-being of the body and ease anxiety levels. It’s recommended that patients consume a well-balanced meal consisting of lean protein, fiber-rich carbohydrates, and healthy fats a few hours before the MRI if possible.

After the scan, it’s important to replenish the body with nutrients to help recover. Patients should aim to consume a balance of protein and carbohydrates to provide the body with energy, manage blood sugar levels, and help maintain muscle mass. Additionally, hydration is essential to help flush out any remaining contrast from the body and prevent dehydration. Drinking water and electrolyte-rich beverages is recommended.

The Hunger Games: Surviving an MRI Scan Without Eating

Refraining from eating before an MRI scan can be challenging for some patients, especially if they are undergoing a lengthy procedure. However, there are ways to curb hunger cravings without breaking the no-food rule. Distractions such as listening to music, meditating, or reading can help take the mind off of hunger. Deep breathing exercises can also help relax the body and take the focus away from hunger pangs. Visualizing a favorite food can help trick the body into thinking it’s eaten something and help satiate hunger temporarily.

Patients should also bring items to keep them occupied during the scan, such as a book or magazine. Some MRI facilities offer headphones or music to help patients relax during the procedure. Comfortable clothing that’s easy to change out of is recommended.

Navigating the MRI Protocol: What Your Doctor Won’t Tell You

Understanding what to expect before, during, and after an MRI scan can help alleviate anxiety and ensure the best possible results. Prior to the appointment, patients should receive specific instructions regarding prep protocol based on their individual needs. This may include avoiding certain medications, specific food and drink restrictions, and any necessary clothing recommendations.

During the procedure, patients lie completely still on a table that slides into a cylindrical tube. The machine will make loud noises, which may sound like banging, thumping, or knocking. Earplugs or headphones may be offered to reduce the noise level.

In some cases, a contrast agent, typically a liquid containing gadolinium, may be injected into the veins during the scan. This enhances the images and makes it easier for medical professionals to spot abnormalities. The contrast is safe for most people but should be avoided in pregnant women or those with severe kidney problems.


An MRI scan is an essential medical procedure that helps diagnose and monitor a variety of conditions. Preparing for the scan properly can help ensure an accurate and effective result. Following the no-food rule before the scan is crucial, as consuming food or liquids can create artifacts in the images that can lead to inaccurate results. Patients should prioritize their health by eating a well-balanced meal before and after the scan, hydrating, and focusing on relaxation techniques during the procedure. With a bit of preparation, patients can navigate the MRI protocol with ease.
