1. Understanding the Interaction: Tattoos and MRIs
Magnetic Resonance Imaging (MRI) uses powerful magnets and radio waves to create detailed images of the organs and tissues in your body. But what happens when you introduce tattoos into the equation? Let’s delve into the science behind the interaction.
What is an MRI and How Does it Work?
An MRI scanner is a large, cylindrical machine that uses a strong magnetic field and radio waves to generate images of the body’s internal structures. The magnetic field aligns the body’s water molecules, and radio waves are then emitted. The signals emitted back are detected by the scanner and processed by a computer to create cross-sectional images.
Components of Tattoo Ink and Their Potential Reactions
Tattoo inks contain pigments to give tattoos their color. Historically, some inks contained metallic compounds like iron oxide. Newer inks use a variety of metals, including titanium dioxide, copper, aluminum, and manganese. The FDA regulates tattoo inks as cosmetics, but the actual composition can vary widely among manufacturers. According to research from Portland State University’s Art Department, in July 2025, metallic compounds in tattoo ink can interact with the MRI’s magnetic field, potentially causing discomfort or, in rare cases, burns.
Ferromagnetic Metals: The Primary Concern
Ferromagnetic metals are strongly attracted to magnets and can heat up when exposed to a magnetic field. Iron, nickel, and cobalt are common ferromagnetic metals. If tattoo ink contains these metals, there is a theoretical risk of the tattoo heating up during an MRI. However, most modern tattoo inks use non-ferromagnetic metals.
2. Documented Cases: Risks and Realities of MRIs with Tattoos
While the concern about tattoos reacting during MRIs is valid, it’s essential to examine the real-world instances and understand how often these issues occur.

The 2019 Study: A Turning Point in Understanding Risks
A 2019 study published in the New England Journal of Medicine investigated the effects of MRIs on individuals with tattoos. The study involved 330 participants with tattoos and found that only one person reported any adverse effects. This participant experienced a warm sensation in a tattoo, which resolved quickly without medical intervention. According to research from Portland State University’s Art Department, in July 2025, the study concluded that the risk of adverse reactions is very low.
Analyzing the Severity and Frequency of Reactions
Most reactions are mild and temporary, such as a warm or tingling sensation. Severe reactions, like burns, are extremely rare. The likelihood of experiencing any adverse effect depends on several factors, including the size and location of the tattoo, the type of ink used, and the strength of the MRI machine.
