Magnetic **** vibration is a common way to test the body today. It changes the magnetic field lines in the body to observe whether the organs in the body appear abnormal situation and whether some diseases are produced.
Because different locations produce different degrees of white and black, each organ is distinguished, thus facilitating the detection of the body. The basic principle of nuclear magnetic **** vibration involves physical knowledge. The human body contains the most atomic nuclei is H1, so the imaging choice is also this, which provides the basis for the success of the examination, the substance is the body's highest magnetic.
During the examination, particles are ordered throughout the magnetic field. There are two general types, low energy levels that are parallel and in the same direction as the larger magnetic field, and high energy levels that are parallel and inverse to the larger magnetic field. When the magnetic field is restored, these particles return to their original state. Different tissues have inconsistent rates of particle recovery because of the different types. Because different tissues can be derived.
Doing nuclear magnetic **** vibration is to detect whether the body parts are not the appearance of mutations, so as to determine whether the emergence of tumors as well as dispersion and development of the direction and speed. This examination can detect the symptoms of the disease early and make timely response to deal with the disease. It can also be used to monitor recovery during treatment. It is also a good test for women who are pregnant.
Because it requires a change in the magnetic field to see how the particles are recovering, the entire procedure takes about 30 minutes. The process requires the help of a medical professional, during which one just has to follow the directions of the medical staff. After it is done, which usually takes a couple of hours, a doctor will give you the results. From the chart, the doctor will be able to figure out if there is any abnormality that is present and summarize it well, and all you need to do during this process is to be quiet and wait. Regular hospitals should be advising the tester to go home and wait for one to three days. There are also hospitals where you can get the results in half a day. If a condition is detected, it is important to seek medical attention for early recovery.

Magnetic **** vibration of the precautions
1, there are magnets in the body of the person, such as the installation of pacemakers, artificial valves, important organs next to a metal foreign body residue, etc., can not do this test, but the body implant confirmed by the surgeon as a non-magnetic object feasible magnetic *** vibration examination.
2, to the technical staff to explain the following: there is no history of surgery; there is no metal or magnetic substances implanted in the body, including metal birth control rings, etc.; there are no dentures, electronic ears, prosthetic eyes, etc.; there is no drug allergies; there is no metal foreign body spilled into the body.
3, do not wear underwear with metal substances, check the head and neck patients should wash their hair the day before the examination, do not rub any hair care products.
4, before the examination need to take off all the clothes outside the underwear, change the magnetic **** vibration chamber of the examination of special clothes. Remove all metal items such as necklaces, earrings, watches and rings. Remove cosmetics, dentures, prosthetic eyes, eyeglasses, and other items from your face.
5, before the examination to provide the doctor with a full medical history, examination information and all the X-ray film, CT film, previous magnetic *** vibration film.
6, abdominal (liver, spleen, kidneys, pancreas, biliary tract, ureter, etc.) examiners to fast for 4 hours before the examination, and an injection of 654-2 before the examination.
7, magnetic *** vibration urography (MRU) before the examination of oral tachycardia 20mg.
8, do magnetic *** vibration examination should be prepared, do not be anxious, afraid, to listen to the physician's guidance, patience and cooperation.
