The Spatially Varying Static Field - Video Lesson

Welcome back everybody to our series on MRI safety. This video is on the spatially varying static field in MRI. It will cover the transient biological effects of the spatially varying static field, the hazards of projectiles in the MRI environment, ways to mitigate these hazards, the impact of the static field on implanted devices, and the importance of screening patients for intraorbital foreign bodies. First, let's talk about the transient biological effects of the spatially varying static field. The spatially varying static field in MRI refers to the magnetic field strength that changes in intensity at different locations within the MRI scanner. As the patient moves through the MRI bore, they experience these variations, which can induce electrical currents in the body and cause transient biological effects, such as dizziness or a metallic taste. While these effects are usually temporary and not harmful, they can cause fear and
