Answer

D. It is more helpful in determining whether surgery is necessary. Explanation 1. Identify the key differences between CT and MRI CT scans use X-ray radiation, while MRIs use magnetic fields. CT is faster and better for imaging bones and detecting acute conditions. 2. Evaluate each option A. CT uses iodine-based contrast, which is not necessarily safer than MRI's gadolinium-based contrast. B. Incorrect; CT uses radiation. C. Incorrect; MRI produces better images of soft tissue. D. Correct; CT is often used to quickly assess trauma and determine surgical needs.
