Whether an MRI of the head is necessary or not depends on the patient’s condition and health.
There is no scientific evidence to prove that MRI of the head cannot be done easily. MRI of the head is basically harmless to the body, which is mainly based on the principle of magnetic resonance, and has no radioactive damage to the body, which is safer and applicable to a wide range.
However, it is important to note that MRI examinations usually take a long time, about 20-30 minutes, or even more than an hour, and the sound is loud. Some patients may experience mild tinnitus symptoms, but usually disappear after a few days, and there is no substantial harm. At the same time there are metal implants in the body can not accept the MRI examination, the magnetic field on the metal will produce adsorption, easy to cause harm to the body and affect the results of the examination.
It is recommended that patients who have the need for head MRI should actively cooperate with the examination according to the doctor’s instructions, so as not to delay the condition.
