Which modality is faster for claustrophobic patients and generally cheaper?

• A. X-ray
• B. CT
• C. Ultrasound
• D. MRI

Answer: (B)

The key idea is how quickly a test can be completed and how much it costs in typical practice. CT scans are designed for rapid image acquisition; a whole study can often be done in just a few minutes with fast patient throughput. This makes CT faster than MRI, which requires longer, more time-consuming sequences and a more confined environment that can be challenging for claustrophobic patients. On the cost side, CT generally costs less than MRI because of shorter scan times, simpler hardware, and higher overall throughput. While ultrasound and X-ray can be quick and inexpensive in many situations, they don’t offer the same breadth of cross-sectional information as CT in a single session, which is why CT is the preferred choice for fast, cost-effective imaging in this context.
