Nerve fiber bundle magnetic resonance technique, an advanced imaging technique, applied in the diagnosis of neuropathy when the doctor suspects an axonal injury or needs to find a relationship between the lesion and the axon. to avoid axonal damage when interfering with the lesion.
1. What is nerve fiber magnetic resonance?
Magnetic resonance imaging of nerve fiber bundles, also known as tension-diffusion magnetic resonance imaging. This is a modern imaging technique in magnetic resonance imaging, applied to detect neurological diseases in which nerve axons are damaged.
Magnetic resonance imaging of nerve fiber bundles is a 3D reconstruction technique that helps to investigate water movement in tissues, providing information on cell density, structural integrity, tumor differentiation, necrosis, normal areas. Usually, differentiate between brain abscess and brain tumor, assess tumor histology, and evaluate nerves using data collected by tension imaging.

2. Purpose of Nerve Fiber Bundle Magnetic Resonance Imaging
The purpose of nerve fiber bundle magnetic resonance imaging to evaluate axonal lesions of the brain, spinal cord or find the relationship between the lesion and nerve fiber bundles, thereby avoiding damage to the nerve fiber bundles when treating injuries.
Resonance imaging method helps doctors detect, diagnose early and correctly diagnose many diseases that were difficult or impossible to diagnose before.
3. When is magnetic resonance imaging of nerve fiber bundles indicated?
Indication of nerve fiber magnetic resonance imaging when the specialist suspects that the patient has a compression injury, invading the nerve fiber bundles or the doctor wants to evaluate the relationship of the affected area. damage to fiber bundles from which to have an appropriate treatment plan, avoiding damage to motor or sensory fiber bundles.
Patients are indicated for nerve fiber magnetic resonance imaging when:
Patients have invasive brain tumors or are located next to axon bundles Multifocal sclerosis, white matter lesions in cerebral infarction, bleeding blood,... Cerebral vascular malformations, need to find the relationship between the malformed area and the axon bundle. Congenital malformations: ectopic gray matter, cleft encephalopathy,... Epilepsy Cerebral palsy In some cases, the patient cannot perform magnetic resonance imaging of nerve fiber bundles if:
The patient has in pacemaker robot, cochlear electrode, automatic medicine pumps in the body In person with magnetic metal (in some cases the doctor still allows it, depending on the patient's health condition) People who are afraid of light morning, fear of lying alone Inability to lie still (however the doctor may prescribe a sedative).

4. Advantages and disadvantages of nerve fiber magnetic resonance technique
Advantages of Nerve Fiber Bundle Magnetic Resonance: Force-driven diffusion imaging is an imaging technique that evolved from simple diffuse magnetic resonance imaging. Therefore, the nerve fiber bundle magnetic resonance imaging technique allows determining the direction as well as the magnitude of the diffusion.
The ability to detect the path of nerve fiber bundles in the brain using force-diffusion imaging is known as neurofibrillation. Nerve fiber bundle image helps create two or three-dimensional images of the brain's nerve fiber system, from which more multi-dimensional images help doctors easily evaluate and detect abnormalities, location of lesions. love.
In brain tumours, nerve fiber magnetic resonance imaging technique allows to determine the invasion or compression of nerve fiber bundles, associated brain tumor and nerve fibers, very important information in planning brain tumor treatment.
Nerve fiber bundle magnetic resonance imaging helps to provide important additional information about many pathological processes in the brain that are not possible or very difficult to be evaluated by conventional magnetic resonance imaging such as tumor, inflammation, and tangle pathology. leukoencephalopathy,...
Disadvantages of Nerve Fiber Bundle Magnetic Resonance Technique There are currently no reports on the harmful effects of magnetic fields on the body. However, the high magnetic field of the nerve fiber magnetic resonance imaging machine can harm metal implants inside the body.
All metal objects need to be removed before the scan, so before taking the scan, the patient needs to inform the medical staff of the magnetic resonance imaging room about information such as: having a hearing aid, a heart valve. artificial, implanted electronic device, metal, denture... in human or not.
Unless absolutely necessary, it should not be used in first-trimester pregnant patients.
Thanks to the development of modern medicine, now the lesions and pathologies related to the nerves and nerve fibers can be detected and diagnosed quickly thanks to the technique of magnetic resonance imaging of nerve fiber bundles. terrible. However, in order to have the best images as well as find the right treatment regimen, patients should choose addresses with quality modern magnetic resonance imaging machines for examination.
