Computed tomography provides

• A. Real-time video of motion
• B. Provides cross-sectional views of the body
• C. Colorized whole-body map
• D. Only 2D projected images

Answer: (B)

Computed tomography provides cross-sectional views of the body. A CT scan uses a rotating X-ray beam and detectors to measure how tissues attenuate X-rays as the patient or the gantry moves, and these data are reconstructed into thin slices that show a single plane of anatomy at a time. You can view these slices in the axial (horizontal) orientation and reform them into coronal or sagittal planes, or create 3D renderings. This cross-sectional perspective lets you see detailed relationships between structures and differentiate tissues by density in grayscale, which is why CT is so effective for evaluating complex anatomy, injuries, and pathology. Real-time motion video (fluoroscopy), colorized whole-body maps, or flat 2D projections are not how CT images are produced.
