What is the image produced on photosensitive film after exposure to radiation and processing called?

• A. Radiograph
• B. CT Scan
• C. Biopsy
• D. EMG

Answer: (A)

The image produced on photosensitive film after exposure to radiation and processing is a radiograph. This X-ray image is created when the film is exposed to X-rays that pass through the body and are then developed chemically to reveal the picture. Bones tend to appear white because they absorb more X-rays, while soft tissues show up in varying shades of gray. CT scans also involve X-rays but produce cross-sectional, computer-generated slices rather than a single radiographic image; a biopsy is a tissue sample taken for microscopic examination; EMG measures electrical activity of muscles.
