CAT stands for which imaging modality?

• A. Computed Axial Tomography
• B. Computed Axial Tomography Imaging
• C. Computerized Angiography Tomography
• D. Computerized Axial Tomography

Answer: (D)

Computerized Axial Tomography is what CAT stands for. The name reflects three ideas: computerized reconstruction, axial slices, and tomographic imaging. Computerized means a computer processes data from multiple X-ray projections to build cross-sectional images. Axial indicates the slices are taken in the axial plane, giving horizontal cross-sections through the body. Tomography means imaging by sections, which lets you focus on one specific layer rather than a single flat projection. This combination provides detailed cross-sectional images to evaluate internal structures and detect pathology quickly. The other options mix terms or add “Imaging” or “Angiography,” which aren’t the standard expansion of CAT. In modern practice the shorthand CT is more common, but the modality remains Computerized Axial Tomography.
