Which imaging method uses X-rays to view bones and detect fractures?

• A. MRI
• B. Ultrasound
• C. X-ray
• D. Computed Tomography

Answer: (C)

The main idea here is identifying the imaging method that uses X-rays to visualize bone and reveal fractures. Plain X-ray imaging (a radiograph) sends X-rays through the body and captures how they are absorbed by tissues. Bone is dense and blocks more X-rays, so it shows up white and clearly outlines bone cortex and any fracture lines or misalignment. This makes X-ray the quickest, most accessible, and typically first-line tool for diagnosing suspected fractures.

Other imaging options work differently. MRI uses magnetic fields and radio waves, not X-rays, and is excellent for soft tissues and bone marrow injuries or occult fractures when X-ray results aren’t conclusive. Ultrasound relies on sound waves and isn’t a primary method for assessing bone fractures, though it can help evaluate surrounding soft tissue injuries in some cases. CT also uses X-rays, but it provides more detailed cross-sectional images and 3D reconstructions, which are especially helpful for complex fractures or surgical planning, and it generally comes after plain X-ray if more detail is needed.
