CT stands for what?

• A. cardiac tomography
• B. cranial tomography
• C. computed tomography
• D. chest tomography

Answer: (C)

CT stands for computed tomography. This imaging method uses X-ray data taken from multiple angles and a computer to reconstruct cross‑sectional images, or slices, of the body. The term "computed" reflects the computer algorithm that builds the images, while "tomography" refers to imaging a specific plane or layer. The other phrases describe applying CT to particular regions (heart, skull, chest), but the general modality is the computed tomography technique itself. A common alternative name is CAT scan, short for computed axial tomography, but CT is the broader, current term.
