Evaluation of Magnetic Resonance Imaging Artifact in Medical Imaging Centers in Khartoum State

Abstract

The aim of this study was to detect the MRI artifacts in medical imaging center in Khartoum and detecting their Causes and remedy made by the technologist to provide information that well serve as useful data base for MRI artifact . Using data sheet filling out by technologist observation to collecting the data along 3 month on Dar Alelaj Specialized Hospital . The result showed the motion artifact was the most dominant type of artifact which is 54% ,then software slice overlap and tissue heterogeneous were had the same percentage (16%) for each ,the MR hardware 8% and the lowest recurrent artifact observed was Fourier transform nyquist sampling by (6%). Through my observation for most common Artifacts in the magnetic resonance imaging centers in Khartoum state we found most common artifacts that is of patient movement (motion Artifacts) due to differentials reasons e.g.: unconscious patient ,lack cooperation and instruction , MR software slice overlap appear from not accurate planning , MR hardware & room shielding caused by some element of coil not working , and Fourier transform & nyquist sampling. The study conclude that the patient motion artifact is the most common .the study recommended that the patient should be instructed before exam and preventive maintenance for MR coils must be keep on .
