The basic principles of MRI is on the basis that nuclei of some elements. when placed in strong magnetic field. placed by magnetic force in one direction. MRI excels in some places and has weakness in some other directions compared to other tools in medical physics. In this research have been investigated weak points of this method. Based on studies on 120 cases that have done MRI, it shows that. inevitable motions such as breathing, heart rate and Prystalsysm and... that come from fear of closed environment or prolongation of MRI examination and as a result fatigue. often causes distortion of the image and create the artifacts that this amount is equal to 77.5% of all patients.
