Which statement about MRI benefits is NOT supported by the material?

Which statement about MRI benefits is NOT supported by the material?

• A. Visualizes soft tissue structures that are not well seen on modalities using ionizing radiation.
• B. MRI uses no ionizing radiation in image development.
• C. STIR sequences readily visualize edema and pathology.
• D. Iodine-based contrast agents are commonly used in MRI.

Answer: (D)

MRI benefits come from its excellent soft-tissue contrast without exposing you to ionizing radiation, and from specialized sequences like STIR that highlight edema and pathology. The idea that iodine-based contrast agents are commonly used in MRI isn’t supported because MRI uses gadolinium-based contrast agents, not iodine-based ones. Iodine contrasts are typically used with CT and other X-ray imaging.
