MRI Equipment Faults - Video Lesson

Hey everybody and welcome back to our course on MRI artifacts. In this lesson, we will focus on gradient equipment faults and the image distortions that occur when the gradient system does not function properly. The gradient system is essentially the spatial localization in MRI and even small disruptions in gradient performance can lead to significant image degradation. Because gradient related distortions affect how anatomy is mapped within the image, they often produce non diagnostic results and require immediate equipment attention rather than protocol modification. Let's get started. To understand how gradient faults impact image quality, it is important to first review the role of the gradient system. Gradient coils are responsible for slice selection, phase encoding and frequency encoding which together allow the MRI system to assign signal to its correct spatial location. By rapidly switching on and off, gradients create controlled variations in the magnetic field that make spatial encoding possible. This process depends on precise timing
