CT or CAT stands for which imaging modality?

• A. Computerized tomography
• B. Computed tomography
• C. Catheterization and therapy
• D. Cardiac tomography

Answer: (A)

CT/CAT imaging uses X-ray beams and computer reconstruction to create cross‑sectional pictures of the body. The acronym CAT comes from Computerized Axial Tomography, so “Computerized tomography” is the expansion that best matches the origin of CAT. While the same imaging technique is commonly referred to today as computed tomography, the term computerized tomography aligns with the CAT lineage. The other options describe unrelated procedures or focuses and do not represent the imaging modality name.
