Which imaging technique uses X-rays to create detailed images of internal structures?

Computed Tomography (CT) is the correct answer because it specifically utilizes X-rays to generate cross-sectional images of the body. During a CT scan, an X-ray beam rotates around the patient, and multiple images are taken from different angles. These images are then processed by a computer to create detailed, three-dimensional representations of internal structures, allowing for the visualization of organs, blood vessels, and other tissues with high precision.

This imaging technique is particularly valuable in medical diagnostics because it provides more detailed information than traditional X-ray imaging. It is used widely in various medical fields, from diagnosing injuries and tumors to planning surgical procedures.

In contrast, ultrasound employs high-frequency sound waves to create images and does not involve X-rays. Magnetic Resonance Imaging (MRI) relies on strong magnetic fields and radio waves instead of X-rays to produce images of the body. Fluoroscopy also uses X-rays but primarily provides real-time imaging, which is useful for observing dynamic processes within the body, rather than generating detailed cross-sectional images. Thus, the unique use of X-rays in a CT scan distinguishes it from these other imaging modalities.
