In order for a doctor to prescribe an MRI procedure, he must have an idea of ​​the patient, know the clinical picture of his illness, all the diseases that he suffered during his life and who still suffer from it. A special role is played by the presence or absence of chronic diseases, since a certain number of them also prohibits the procedure of MRI.At the time of the tomography, the patient should not have any complaints of poor health.

If earlier there were some serious injuries that required a doctor, if some operations were carried out, the medical personnel should also be informed. The doctor should analyze all serious cases of treatment of the patient for medical assistance and only then decide on the appointment of an MRI procedure.
