Which statement about ALARA is true?

Which statement about ALARA is true?

• A. ALARA seeks to maximize image quality regardless of exposure.
• B. ALARA aims to keep exposure as low as reasonably achievable while achieving clinical goals.
• C. ALARA is only about reducing exposure to ultrasound-generated energy.
• D. ALARA applies only to pediatric patients.

Answer: (B)

ALARA means keeping radiation exposure as low as reasonably achievable while still obtaining the necessary clinical information. This idea centers on a careful balance: you want enough image quality to diagnose or guide treatment, but you don’t expose the patient to more radiation than needed to achieve that goal. In practice, this means using the lowest dose settings that still yield acceptable images, employing shielding and precise collimation, avoiding repeats, and considering alternative, lower-dose or non-radiation-based methods when appropriate. It isn’t about maximizing image quality at all costs, nor is it limited to ultrasound or to pediatric patients; it applies across imaging scenarios where exposure to ionizing energy is involved, with extra caution for sensitive populations when relevant.
