Is the nuclear magnetic radiation high?

The radiation from nuclear magnetic resonance is relatively high, because this method uses the nuclear magnetic resonance method for examination. You need to remove any metal from your body, and make sure you are on an empty stomach and drink plenty of water before the examination, which will help make the boundaries between the liver and spleen clearer. Regarding the radiation from MRI, we should pay attention to skin care after surgery to avoid strong exposure to sunlight. This method can also be used to examine tumors.

Nuclear Magnetic Resonance

Finding the lesion

Magnetic resonance imaging is the latest medical imaging technology that uses the principle of nuclear magnetic resonance. It has excellent diagnostic capabilities for solid organs such as the brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal glands, uterus, ovaries, prostate, as well as the heart and large blood vessels. Compared with other auxiliary examination methods, MRI has the advantages of multiple imaging parameters, fast scanning speed, high tissue resolution and clearer images. It can help doctors "see" early lesions that are difficult to detect. It has become a powerful tool for early screening of tumors, heart disease and cerebrovascular disease.

It is understood that since metal will interfere with the external magnetic field, patients must remove all metal objects on their bodies before undergoing an MRI examination. Do not wear magnetic items such as watches, metal necklaces, dentures, metal buttons, metal contraceptive rings, etc. during MRI examination. In addition, people who wear pacemakers or have paramagnetic metal implants in their bodies, such as metal clips, stents, plates, and screws, cannot undergo MRI examinations. You must fast when performing MRI examination of the upper abdomen (such as liver, pancreas, kidney, adrenal gland, etc.), but you can drink plenty of water before the examination to help make the boundaries between the stomach, liver, and spleen clearer.

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 "high blood pressure, high blood lipids, and high blood sugar", MRI examinations of the head and heart 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 the doctor's advice for examination and not to think that the more expensive the imaging examination, the better. Only the examination that suits you is the best.
