An MRI scanner is a type of medical scanning equipment. It is an equipment that can capture pictures of brain activity, and then use some software to restore the images seen by the subject.
MRI Applications
v Found Lesions
Magnetic resonance imaging is the latest medical imaging technology using the principle of nuclear magnetic resonance. It has excellent effects on brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal gland, uterus, ovary, prostate and other solid organs as well as the heart and great vessels. diagnostic function. 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 not easy to detect. A sharp tool for early screening of vascular diseases.
It is understood that metals will interfere with the external magnetic field, patients must remove all metal objects on their bodies before undergoing MRI examinations. Magnetic items such as watches, metal necklaces, dentures, metal buttons, and metal contraceptive rings cannot be worn for MRI examinations. In addition, people who wear a pacemaker and have paramagnetic metal implants in the body, such as metal clips, stents, steel plates, and screws, cannot undergo MRI examinations. An MRI examination of the upper abdomen (such as liver, pancreas, kidney, adrenal gland, etc.) must be performed on an empty stomach, but sufficient water can be drunk before the examination, which will help the boundary between the stomach, liver, and spleen become clearer.
v Found Tumor
MRI is the most effective diagnostic imaging method for brain, spinal cord and other diseases. It can not only detect early tumors, cerebral infarction, cerebral hemorrhage, brain abscess, cerebral cysticercosis and congenital cerebrovascular malformations, but also determine the types of hydrocephalus and reason etc. As for breast cancer, which is the largest gynecological disease that endangers the life and health of Chinese women, accurate screening by MRI can help to find early lesions of breast cancer; MRI examinations of the head and heart can be used to detect high-risk diseases such as heart disease and cerebral infarction early, before a red light is issued for health. In addition, MRI can also perform abdominal and pelvic examinations, such as liver, gallbladder, pancreas, uterus, etc. Abdominal great vessels and extremity angiography can clearly diagnose true and false aneurysms, dissecting aneurysms and extremity blood vessels of various lesions. MRI is very precise in diagnosing various joint tissue lesions, and is very sensitive to aseptic necrosis of bone marrow and bone.
v Harmless
Since MRI is magnetic field imaging and has no radiation, it is harmless to the human body and safe. As far as we know, there are neither any reports on the harm caused by the use of nuclear magnetic resonance examinations in the world, nor have we found any increase in the incidence of gene mutations or chromosomal aberrations in patients who have undergone nuclear magnetic resonance examinations. Although MRI is unique in screening early lesions, any inspection has its limits. For example, some patients are not suitable for MRI, so do not over-check. He appealed that any patient should follow the doctor’s advice for examination. Don’t think the more expensive the imaging examination, the better. Only the examination that suits you is the best.
