The unit of Bq would be used in what imaging modality?

• A. Radiography
• B. CT
• C. MRI
• D. Nuclear medicine

Answer: (D)

Becquerel is the unit for radioactivity, used to quantify how much radioactive material is present or how active a radiopharmaceutical is. In nuclear medicine, patients are given radioactive tracers that emit radiation detectable by the camera, and the activity of those tracers is described in Becquerels (or curies). That makes this modality the one where Bq is relevant. In contrast, radiography, CT, and MRI rely on X-ray exposure or magnetic fields and dose measurements or field strengths (like mGy, CTDI, or tesla), not radioactivity levels, so the Becquerel wouldn’t be used there.
