What is the imaging technique that rotates around the patient to create pictures of organs and surrounding tissues?

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

Answer: (C)

Computed tomography is the imaging method described. In CT, an X-ray tube and detectors sit on a gantry that rotates around the patient. As it turns, X-ray beams pass through from many angles, and the returning signals are fed into a computer to reconstruct cross-sectional pictures of organs and surrounding tissues. This rotation and reconstruction produce detailed slices and even 3D views, helping visualize both soft tissue and bone quickly and clearly. X-ray radiography provides a single image from one angle, so it lacks the multi-angle detail CT offers. Ultrasound uses sound waves, not radiation, to create live images. MRI uses magnetic fields and radiofrequency rather than rotating X-ray beams and does not rely on the same angular acquisition as CT.
