Is MRI harmful to the body, and if so, how harmful?

MRI is not harmful to the body.

1. Since NMR is magnetic field imaging, not X-ray, it is not radioactive, so it is harmless to the human body and is very safe. So far, there have been no reports of harm caused by the use of MRI machines in hospitals, and no increased incidence of genetic mutations or chromosomal aberrations has been found in patients.

2. Magnetic resonance imaging is an examination method that uses an electronic computer to analyze and diagnose the image of the human body, which does not use X-rays, but magnetic fields, and its basic principle is that the hydrogen atoms contained in the human body will resonate after giving a specific high wave under a strong magnetic field, producing a high wavenumber of electromagnetic waves. Nuclear magnetic resonance (NMR) takes advantage of this property by using an electronic computer to collect, process, and graphize changes in the magnetic field.

3. MRI can show fat, organs, muscles, fast-flowing blood, bones and air. The internal structure of the organ can also be clearly displayed. Doctors can well identify tumors, inflammation, necrotic lesions, abnormal material deposition, functional obstruction, blood circulation obstruction and other lesions in the patient's body.

It is of great help in the diagnosis of various diseases of the nervous system, chest, abdomen and limbs.

There is no harm, CT and radiation are harmful.

Frequent nuclear resonance will disrupt the endocrine, and will also cause some chronic diseases and affect the growth of white blood cells, especially leukemia. It will affect the stomach and intestines, and the body will become very weak.

Doing "nuclear magnetic resonance" often has some radiation effect on the human body, don't do it often, it is easy to hurt people's **, hurt **surface, and harmful to **.

There are harms, nuclear radiation is more serious, so it will hurt **, affect attention, memory, cranial nerves, and in severe cases, it will lead to cancer.

Difference Between MRI and CT.

Computed tomography (CT) can accurately detect small differences in density between different tissues in a cross-sectional anatomical plane, and is an ideal examination method for observing bone, joint and soft tissue lesions. In the diagnosis of arthritis, it is mainly used to examine the spine, especially the sacroiliac joint. CT is superior to conventional x-rays because of its high resolution and its ability to do axial imaging.

Due to the high density resolution of CT, soft tissues, bones, and joints can be clearly defined. In addition, CT can be used for axial scanning, and some joints that are difficult to distinguish on traditional X-ray images can be "exposed" on the ding image. If the articular surface of the sacroiliac joint is naturally inclined and curved, and there is overlap of other tissues, although x-rays of the sacroiliac joints may be sufficient in most cases, sometimes it is difficult to detect sacroiliitis on x-rays, and CT can be done for the patient in question.

Magnetic resonance imaging (MRI) is obtained based on the interaction of radiated waves and protons in a strong magnetic field. As soon as magnetic resonance was introduced, it quickly became a useful imaging tool in the diagnosis of many diseases, including the musculoskeletal system. The musculoskeletal system is best suited for magnetic resonance imaging because of its wide range of tissue density contrasts.

In the diagnosis of bone, joint and soft tissue lesions, magnetic resonance imaging has several times more imaging parameters than CT and a high degree of soft tissue resolution, which makes the contrast of soft tissue significantly higher than that of CT. Through its multi-directional plane imaging function, magnetic resonance imaging can significantly improve the imaging quality of each joint by using high-resolution poison surface coils, so that nerves, tendons, ligaments, blood vessels, cartilage and other subtle results that cannot be distinguished by other imaging examinations can be displayed. The disadvantage of magnetic resonance imaging in the osteoarticular system is that it is non-specific for the qualitative diagnosis of bone and soft tissue lesions, and the imaging speed is slow during the examination.

The patient's voluntary or involuntary movement can cause motion artifacts that can affect the diagnosis.

MRI is not harmful to the body.

Because it is magnetic imaging and is not radioactive, it is harmless to the human body and is very safe.

MRI is the most effective imaging diagnosis method for diseases of the brain and spinal cord. It can not only detect tumors, cerebral infarctions, cerebral hemorrhages, brain abscesses, neurocysticercosis, and congenital cerebrovascular malformations, but also determine the type and ** of hydrocephalus.

Breast cancer is the biggest disease that endangers the life and health of women in China, and accurate MRI screening can help to detect the early lesions of breast cancer; For the three groups of people, such as hypertension, hyperlipidemia, and hyperglycemia, MRI examination of the head and heart can detect early heart disease and brain tissue, and send a red light alarm for high-risk diseases such as cerebral infarction.
