A CAT Scan provides what type of image?

• A. EEG
• B. MRI
• C. PET Scan
• D. CAT Scan

Answer: (D)

The main idea here is recognizing what each imaging method actually shows. A CAT Scan uses X-ray beams with detectors to create cross-sectional, or tomographic, images of the body. It builds up detailed slices that can be stacked to form a 3D view of structures inside. This is different from EEG, which measures brain electrical activity rather than producing images; MRI, which uses magnetic fields and radio waves to image soft tissues; and PET, which maps metabolic activity with radioactive tracers. So the image produced is a cross-sectional, computed-tomography image.
