What aspects of the disease can MRI be effective for? The experts tell you!

It has excellent diagnostic function for solid organs such as brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal glands, uterus, ovaries, prostate, as well as heart and large blood vessels. Compared with other auxiliary examination methods, MRI has the advantages of more imaging parameters, fast scanning speed, high tissue resolution and clearer images, which can help doctors see early lesions that are not easy to detect, and has become a powerful tool for early screening of tumors, heart diseases and cerebrovascular diseases.
Including cerebral atherosclerosis, thrombosis, stenosis, occlusion, cerebral arteritis, cerebral artery injury, cerebral aneurysm, intracranial vascular malformation, cerebral arteriovenous fistula, etc.
Cranial tumors: tumors of the nervous system that occur in the cranial cavity, including tumors originating from neuroepithelium, peripheral nerves, meninges, and germ cells, tumors of lymphoid and hematopoietic tissues, craniopharyngiomas and granulosa cell tumors in the sellar region, and metastatic tumors.

The MRI used in medicine is mainly used to check for some, such as diseases of the central nervous system and digestive system, which will have a good diagnostic effect on this disease, of course, there are some contraindications to MRI, such as patients with severe phobia of the right arm, and there are metal implants in the body that cannot be examined by MRI.
-
Lumbar disc herniation, cardiovascular disease, brain tumor, breast disease, central nervous system, and other diseases all have certain advantages.
-
The main stream at the bone and joint, the main stream at the digestive tract, the secondary tumor, the detection of the ligament level, the disease of the breast, and the disease of ** are all very advantageous.

Magnetic resonance imaging is a new medical imaging technology that uses the principle of magnetic resonance, which has excellent diagnostic functions for the brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal glands, uterus, ovaries, prostate and other solid organs, as well as the heart and large blood vessels.
Magnetic resonance imaging (MRI) is currently the most effective imaging diagnosis method for cranial and spinal cord diseases, which can not only detect tumors, cerebral infarction, cerebral hemorrhage, brain abscess, neurocysticercosis and congenital cerebrovascular malformations, but also determine the types and causes of hydrocephalus.
Since MRI is magnetic field imaging and is not radioactive, it is harmless to the human body and is very safe.

MRI can examine neurological lesions, including tumors, infarctions, hemorrhages, degeneration, congenital malformations, infections, etc., almost.
The right becomes a means of diagnosis. In particular, lesions of the spinal cord and spine such as tumors, atrophy, degeneration, traumatic disc lesions, etc. are the preferred examination methods.
MRI can also check for lesions in the heart's large blood vessels; Lesions of the mediastinal diaphragm in the lungs. examination of the abdomen and pelvic organs; Biliary system, urinary system and other diseases, the diagnosis of diseases is significantly better than CT. soft tissue lesions on joints; It is very sensitive to aseptic necrosis of bone marrow and bone, and lesions are detected earlier than x-rays and CT.
Magnetic resonance imaging has a wide range of applications, and it is the most effective imaging diagnosis method for cranial and spinal cord diseases. It can detect tumors, cerebral infarctions, cerebral hemorrhages, brain abscesses, neurocysticercosis and congenital cerebrovascular malformations at an early stage, and can also determine the types and causes of hydrocephalus. Magnetic resonance imaging is unique in showing congenital abnormalities of the spinal cord, syringomyelia and sclerosis, and tube scarring.
Magnetic resonance imaging is also very clear in showing disc herniation, degenerative lesions, etc., and disc herniation can also be clearly displayed in compression of nerve roots. MRI can provide well-defined images of the heart's atrium, ventricular septum, heart valves, and myocardium. Therefore, congenital heart disease and various cardiomyopathies are adaptations of magnetic resonance examination.
Magnetic resonance imaging can also be used to examine tumors of the uterus, ovaries, bladder and prostate, and can stage cancers, and tumors of the liver and pancreas can also be clearly displayed.

Nuclear magnetic resonance is related to the spin of the nucleus and is described through quantum mechanics. The basic principle is that a nucleus with an appropriate spin angular momentum can produce NMR, whereas Planck's constant is defined as spin angular momentum.

The first scientist to record resonance --- Mozi.
1. As early as the early Warring States period, people at that time invented all kinds of resonators to detect the enemy. "Mozi Beixue" records several of them: >>>More
Heart disease itself doesn't necessarily require an MRI, and it doesn't necessarily have much of an advantage. In general, the value of MRI in judging arrhythmia itself is not as great as that of electrocardiogram and electrophysiological examination, and the exploration of the gross structure of the heart is generally sufficient. MRI is only advantageous in cases where some ultrasound is not sufficient, such as aortic dissection. >>>More
