Is MRI harmful to the body?

MRI scans generally pose no harm to the body and are considered a safe imaging method. MRI uses strong magnetic fields and radiofrequency waves to generate detailed images of internal body structures. Unlike X-rays or CT scans, the process does not involve ionizing radiation and therefore does not cause radiation-related damage. Most people can complete the examination without difficulty, although a few individuals may feel uncomfortable due to the confined space of the scanning environment or may be restricted due to implanted metallic objects. Additionally, some patients may be sensitive to contrast agents used during the scan, so it is important to inform the doctor in advance about any relevant medical history.

To ensure the examination proceeds smoothly, it is recommended to understand the scanning process beforehand and provide your doctor with detailed information regarding your health status, particularly whether you have any metallic implants, are possibly pregnant, or have a history of allergies. Prior to the scan, remove all metal objects, such as jewelry, watches, etc., to avoid interference with the magnetic field. If you feel anxious about the confined space, discuss this with your doctor and seek methods to alleviate anxiety. After the examination, pay attention to any bodily reactions, and seek prompt medical consultation if you experience abnormal symptoms such as dizziness, nausea, or localized discomfort.
