Does MRI have any side effects? MRI is one of the more familiar tests, but the most common concern is whether it will have side effects on the body. If you have these concerns, why don’t you read on to find out more about MRI side effects? What is MRI MRI not only provides more information than many other imaging techniques in medical imaging, but also differs from existing imaging techniques, so it is potentially superior for the diagnosis of diseases. MRI is very effective in detecting intracerebral hematomas, extracerebral hematomas, brain tumors, intracranial aneurysms, arteriovenous malformations, cerebral ischemia, intravertebral tumors, spinal cord cavitation and spinal fluid, and other common cranio-cerebral diseases. It is also effective in the diagnosis of posterior lumbar disc protrusion, primary liver cancer and other diseases. At the same time, does MRI have any side effects? The basic principle is that the hydrogen atoms contained in the human body will resonate when given a specific high wave in a strong magnetic field, producing a high wave number of electromagnetic waves. MRI takes advantage of this property and uses an electronic computer to collect, process and graph the changes in the magnetic field. MRI can show fat, whole body organs, muscles, fast flowing blood, bones and air. The internal structure of the organs can also be clearly displayed. Doctors can well identify lesions such as tumors, inflammation, necrotic lesions, abnormal material deposits, functional obstruction, and blood circulation obstruction in the patient’s body. It provides great help in the diagnosis of various diseases of the nervous system, chest, abdomen and extremities. Since MRI is magnetic field imaging, not X-rays, there is no radioactivity, so it is harmless to human body and is very safe. Through the above introduction, do you have a new understanding of MRI?
