The statement 'ALARA aims to reduce exposure at the expense of diagnostic image quality' is true or false?

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (B)

ALARA means exposing patients to the smallest radiation dose that still yields clinically useful images. It’s about optimization, not sacrificing image quality. So the statement is false: you don’t reduce dose at the expense of diagnostic usefulness. If lowering the dose would make the image nondiagnostic, the approach would be to adjust technique or use alternative methods to maintain diagnostic quality while continuing to minimize exposure. In practice, this includes selecting appropriate exposure factors, using shielding and collimation, and applying dose-saving technologies to achieve the needed image quality with the lowest reasonable dose.
