How Radiofrequency Power Emissions Affect MRI Safety

MRI radiofrequency (RF) power emissions determine the specific absorption rate (SAR), which quantifies tissue heating. Understanding RF power limits is essential for preventing patient burns and ensuring safe scan protocols.

• Educational Q&A from MRI Questions (Elster) covering RF power basics, SAR, and safety limits.
• Relevant for radiology residents and technologists preparing for board exams or seeking to understand MRI physics.
