Which imaging technique uses a series of X-ray photographs taken from different angles and processed into a slice of the body?

• A. CT Scan
• B. MRI
• C. PET
• D. Ultrasound

Answer: (A)

CT imaging works by taking many X-ray pictures around the body as the scanner rotates, and then using a computer to reconstruct those projections into cross-sectional slices. This series of slices can be viewed in different planes, giving precise, detailed images of both bone and soft tissue and enabling accurate localization of structures or injuries. MRI uses magnetic fields and radio waves to image soft tissues without ionizing radiation, PET relies on a radioactive tracer to show metabolic activity, and ultrasound uses sound waves to create real-time images. The description with rotating X-ray photographs processed into slices points to CT.
