Abstract :
The objective of this study was to assess the effect of extending pre-scan written information to patients undergoing head magnetic resonance imaging (MRI) examinations on motion artifacts. A controlled study was conducted in King Fahad hospital at the department of Radiology. A total of 100 patients were involved; 50-patients received only routine oral hospital instructions (control group), and another 50-patients received pre-scan extended written beside routine oral hospital instructions (study group). The head MRI images were assessed with regard to motion artifacts. Informed consent was obtained from all the patients included in the study. The incidence percentage of motion artifacts were significantly fewer in the study (intervention group than in the control group,10%, 58% respectively,). The P value = 0.001. The motion artifacts decrease significantly in the study group than in the intervention group. Extending written information before MRI scan could significantly reduce motion artifacts and improve image quality.
