Magnetic Resonance (MR) Method

Magnetic resonance (MR) is a technology used for medical imaging. MR uses magnetic fields and radio waves to visualize tissues inside the body in detail and to obtain cross-sectional images of the examined area. MR creates images based on the water content, density, and molecular structures of different tissues. In this way, the diagnosis and monitoring of many diseases and conditions become possible.

MR imaging consists of a series of steps. In the first step, the patient’s body is exposed to a strong magnetic field. This magnetic field affects the magnetic alignment of the hydrogen atoms in the body. Then, a radio wave is applied to excite the hydrogen atoms, and their energy emissions are detected. The detected data is processed by computers to create cross-sectional images.

MR imaging is used for many medical purposes. It is used in areas such as disease diagnosis, treatment planning, and monitoring health problems.

MR imaging is used in many situations. For example, it is used in the diagnosis of diseases, injury assessment, fetal imaging, and the evaluation of many medical conditions such as heart and vascular diseases.

Generally, no special preparation is required for an MR scan, but in some cases, it may be necessary to remove metal objects, follow fasting or fluid intake instructions, use contrast agents, or wear comfortable clothing. Your doctor or technician will provide you with specific instructions.

Silence, stillness, and comfort are important during an MR scan. Loud noises may occur, so protective headphones are provided, and movement can affect image quality.

MRI scanning is generally a safe procedure and does not involve radiation. However, in some cases, a contrast agent may be used, and there is a risk of an allergic reaction to this agent. Additionally, it should be remembered that certain metal objects or devices can react to the magnetic field. Therefore, you should share your full medical history with your doctor or MRI technician before having an MRI scan.

Contrast agent helps the MRI scan obtain more detailed images in certain areas. This agent can be injected intravenously and is carried to specific parts of the body. The contrast agent creates better contrast in certain areas such as blood vessels, organs, or lesions, allowing doctors to make a more accurate diagnosis.
