MRI Physics: High Slew Rate Questions Answered

High gradient slew rate enables faster MRI but increases peripheral nerve stimulation risk. This educational Q&A from MRI Questions explains the trade-offs for radiologists and trainees.

• The post explains how slew rate (rate of gradient change, dB/dt) determines minimum echo spacing and peak gradient performance, directly affecting scan speed.
• Elevated slew rates can induce peripheral nerve stimulation, a key safety constraint in clinical and research MRI systems.
• Intended for radiologists, technologists, and physics trainees preparing for board examinations or improving protocol understanding.
