MRI Shading Artifact - Video Lesson

Hey everybody. Welcome back to today's lesson on artifacts in MRI. This lesson focuses on shading artifact, a common MRI image quality issue encountered in routine scanning. Understanding shading artifact is essential because it often reflects a correctable problem involving coil sensitivity, field uniformity or sequence design. Recognizing it quickly protects image quality, patient safety and diagnostic accuracy. Let's get started. Shading artifact appears as a difference in signal intensity across the image where the image shows uneven brightness or uneven signal across the anatomy. Instead of the tissue signal appearing consistent from one side of the image to the other, the brightness varies in a gradual pattern. This can show up on the image in multiple ways as smooth areas of uneven signal, as gradual transitions from bright to dark, as a region that appears washed out or shadowed, or as non uniformity that may affect only part of the anatomy or the entire field of view.
