Is head MRI harmful to the human body?

With the development of science and technology, more and more people have undergone head MRI, which is an advanced medical technology that uses the principle of magnetic field to help doctors find difficult-to-detect affected areas on the patient's body and detect the diseased area in time. It is very helpful in preventing the worsening of cancer. Let's take a look at whether head MRI is harmful to the human body?

Found a tumor

Magnetic resonance imaging is currently the most effective imaging diagnostic method for diseases of the brain, spinal cord, etc. It can not only detect tumors, cerebral infarction, cerebral hemorrhage, brain abscess, cerebral cysticercosis and congenital cerebrovascular malformations at an early stage, but also determine the type and cause of hydrocephalus. As for breast cancer, the number one gynecological disease that threatens the life and health of Chinese women, precise screening through MRI can help detect early lesions of breast cancer. And for people with "three highs" such as high blood pressure, high blood lipids and high blood sugar, MRI examinations of the head and heart and other parts can be used to detect high-risk diseases such as heart disease and cerebral infarction at an early stage before their health sends out red warning signs. In addition, MRI can also be used for examinations of the abdomen and pelvis, such as the liver, gallbladder, pancreas, uterus, etc. Imaging of the large abdominal blood vessels and limb blood vessels can clearly diagnose true and false aneurysms, dissecting aneurysms and various lesions of the blood vessels in the limbs. Magnetic resonance imaging is very accurate in diagnosing various types of joint tissue lesions and is very sensitive to aseptic necrosis of bone marrow and bone.

Harmless to humans

Since MRI is magnetic field imaging and has no radioactivity, it is harmless to the human body and is very safe. As far as we know, there are currently no reports in the world about the harm caused by the use of MRI examinations, nor has there been any increase in the incidence of gene mutations or chromosomal aberrations in patients due to MRI examinations. Although MRI is unique in screening early lesions, any examination has its limitations. For example, some patients are not suitable for MRI, so do not over-examine them. He called on all patients to follow their doctor's advice for examination and not to think that the more expensive the imaging test, the better. Only the test that suits them is the best.

From the above information, it can be seen that there is no harm in doing an MRI. At the same time, the more expensive the MRI is, the better it is. You have to choose the one that suits you. Since MRI is extended from the magnetic field, you need to take off all magnetic items on your body during the examination to avoid interference and errors.
