Core Concepts Of MRI Artifacts

This module introduces the essential principles of MRI artifact recognition and explains how motion susceptibility chemical shift aliasing and hardware limitations influence image appearance. It describes how technologists identify artifact patterns evaluate their causes and apply corrective strategies. The content highlights the importance of understanding how pulse sequences gradients field strength and coil selection contribute to artifact formation. It also explains how patient communication immobilization and breath hold coaching reduce motion related issues. The module emphasizes the importance of recognizing artifacts that mimic pathology and ensuring accurate interpretation. By understanding how MRI artifacts arise technologists can improve image quality reduce repeat exams and support confident diagnosis.
