All you need to know about MRI: Operation, Use and Side Effects

In the medical field, MRI (Magnetic Resonance Imaging) represents a major technological advance in the diagnosis and study of the internal structures of the human body. Understanding how it works, its applications and possible side-effects is essential for patients and healthcare professionals alike. In this article, we'll explore in detail everything you need to know about MRI.

What is an MRI scan?

MRI uses the magnetic field to produce precise, detailed images of the body's internal tissues. By exploiting the behavior of hydrogen atoms present in the body's water molecules, MRI generates signals which are then converted into images by a dedicated device. This technology is particularly useful for studying the brain, spinal cord, muscles and tendons.

Why have an MRI scan?

MRI is often recommended for diagnosing and evaluating a variety of medical conditions, including brain lesions, tumors, spinal cord injuries, musculoskeletal disorders and neurological diseases. Thanks to its ability to provide detailed images of soft tissues, it offers unrivalled accuracy in diagnosis and treatment planning.

MRI side effects:

Although MRI is generally considered safe, some side effects may occur. People with tattoos may experience burning of the tattooed skin due to the presence of metallic pigments. It is therefore important to inform the medical staff of any tattoos prior to the examination. In addition, contrast agents may be used during MRI, although their nature differs from those used in other medical imaging examinations. These products can sometimes provoke allergic reactions in certain individuals.

MRI is a powerful and versatile medical imaging technique used to diagnose and evaluate a wide range of medical conditions. By understanding how it works, its applications and possible side effects, patients can make informed decisions about their health. It is also crucial to communicate with medical staff to discuss any concerns or questions prior to the examination.
