Which statement about MRI characteristics is true?

• A. MRI is inexpensive
• B. MRI is moderate to expensive
• C. MRI is inexpensive
• D. MRI is extremely cheap

Answer: (B)

Cost considerations drive how imaging modalities are used in practice. MRI carries higher costs due to the powerful superconducting magnet, specialized shielding and infrastructure, ongoing maintenance and cryogenic systems, and the need for highly trained personnel to operate the scanner and interpret results. The hardware and facility requirements, plus longer scan times, mean imaging capacity per day is lower and the per-study cost is higher. Because of these factors, MRI is best described as moderate to expensive rather than inexpensive or extremely cheap.
