Magnetic resonance imaging (MRI) uses a constant magnetic field and radio waves, a non-invasive method for examining tissues, organs and the skeletal system. The advantages and disadvantages of MRI is not fully understood. In the computerized tumor (CT) scan, as an invasive method, the x-rays of the body is used for tomography; which different x-ray attenuation coefficient in tissues as well as the reconstruction of images could affect on the scanning of the patient and the received amount of radiation by the patient. However, compared to other radiographical diagnostic methods, CT scan could lead to the exposure of the patients against substantial radiation dosage, which may have several radiobiological effects such as delayed effects of radiation (possible effect) with the result of a variety of cancers, chromosomal failures and potential genetic abnormalities in the future generations. It is recommended that these tests would prescribe for the patients with greater accuracy and caution; with application of magnetic dosimeter for monitoring exposure of people who working with MRI (as its application for X-ray and CT scan).
