Which statement best describes the goal of dose reduction in radiography?

• A. Maximize image quality at any dose
• B. Deliver only the doses required for patient care
• C. Eliminate radiology
• D. Shield every body part on every patient

Answer: (B)

The goal of dose reduction in radiography is to keep the patient’s radiation exposure as low as reasonably achievable while still obtaining a diagnostic image. This means exposing only the amount necessary to answer the clinical question and support patient care, balancing image quality with safety. The best statement reflects this balance by saying we deliver only the doses required for patient care, which aligns with the ALARA principle. In practice, this involves optimizing technique, using proper collimation to limit the irradiated area, applying shielding when appropriate without compromising the exam, and avoiding repeat exposures. The other ideas miss the balance: trying to maximize image quality at any dose can lead to unnecessary radiation; eliminating radiology isn’t practical or patient-centered; shielding every body part on every patient is neither feasible nor always appropriate and can interfere with the needed exam.
