Which imaging modality is described as a computed tomography scan?

• A. TTP
• B. CT Scan
• C. Endoscopy
• D. Idiopathic

Answer: (B)

Computed tomography is an imaging modality that uses X-rays with computer processing to create cross-sectional images of the body. The phrase “computed tomography scan” directly refers to this method, so the option named CT Scan is the match. The other terms don’t describe an imaging technique: endoscopy uses a scope to visualize internal surfaces, TTP isn’t an imaging modality, and idiopathic means of unknown cause.
