How to do a head MRI?

CT is a widely used medical examination device. Following the CT machine, a magnetic resonance imaging technology emerged. This technology is safer and more convenient than CT. It is a major advancement in medical imaging. Therefore, it is best to use magnetic resonance imaging technology for head examinations. Let me first introduce you to MRI examination.

Magnetic resonance imaging is another major advancement in medical imaging after CT. Since its application in the 1980s, it has developed at a very rapid pace. The basic principle is to place the human body in a special magnetic field and use radio frequency pulses to excite the hydrogen nuclei in the human body, causing the hydrogen nuclei to resonate and absorb energy.

After the radio frequency pulse is stopped, the hydrogen nuclei emit radio signals at a specific frequency and release the absorbed energy, which is received by receivers outside the body and processed by a computer to obtain an image. This is called magnetic resonance imaging. Nuclear magnetic resonance imaging has completely gotten rid of the damage of ionizing radiation to the human body. It has many parameters, a large amount of information, multi-directional imaging, and high resolution of soft tissue. Since its advent, it has attracted the attention of scholars from all walks of life. Whether it is the improvement of equipment, the update and upgrade of software, or the research on the diagnostic function of organs in various parts of the body, it has developed very rapidly. It is now mature and is widely used in the diagnosis of clinical diseases. It has become an indispensable examination method for some lesions.

Nuclear magnetic resonance is a physical phenomenon. As an analytical method, it is widely used in physics, chemistry, biology and other fields. It was not until 1973 that it was used in medical clinical testing. To avoid confusion with radiological imaging in nuclear medicine, it is referred to as magnetic resonance imaging (MR).

The above is some information that the editor has found related to MRI technology. Regarding MRI technology, MRI is relatively safe, and it has excellent results for brain examinations. It has also been suggested before that you should use MRI examinations to get insurance when performing brain examinations.
