On examination the patient is placed on a narrow platform on the back of the scanner.To secure the body in position using pillows and belts.Then the platform is moved to the annular portion scanner, where it remains during diagnosis.

During the MRI apparatus using the open-loop radiating part of the equipment is located directly above the platform, and the sick - in open space.This allows the procedure to those who suffer from claustrophobia.In addition, such equipment has no restrictions on the patient's weight.

scan result is a series of thin sections from which the computer builds a volumetric three-dimensional model of the surveyed area.During the procedure, the patient should be in a stationary state so as not to affect the shar

pness of images.The study duration is approximately 30 minutes.

How to prepare?

Special training for MRI teeth is required.The only thing it should be recalled - it is necessary to inform a specialist on the availability of dental implants, pins or braces (these things can affect image quality).The doctor did not cancel the MRI procedure, but will make some adjustments in the survey, in particular, change the settings of the scanner.

It is worth to take a place and an X-ray picture, which establishes the pins or implants - it is much easier procedure.

Since the work is accompanied by a rather intense scanner noise, sometimes sampled person offer ear plugs or special headphones.
