Which technique is used to minimize radiation exposure during diagnostic imaging?

The choice of only performing necessary imaging is the correct technique to minimize radiation exposure during diagnostic imaging. This principle is rooted in the concept of justifying the use of radiation by ensuring that any imaging performed is clinically warranted. When healthcare providers evaluate the need for imaging, they can avoid unnecessary procedures that would expose patients to radiation without significant benefit to their diagnosis or treatment.

Emphasizing this approach aligns with the "As Low As Reasonably Achievable" (ALARA) principle, which advocates for optimizing radiation doses while maintaining high-quality imaging results. By limiting imaging to only what is necessary, healthcare professionals can significantly reduce the cumulative radiation dose to patients. This is particularly important considering the cumulative effects of radiation exposure over a person’s lifetime.

In contrast, the other options involve actions that would either increase radiation exposure or do not prioritize patient safety and health. For instance, using the highest possible dose would clearly lead to higher radiation exposure without any clinical justification. Ignoring patient feedback would disregard important information that may influence the necessity and frequency of imaging. Regular equipment malfunctions would not only compromise the quality of imaging but could also lead to unnecessary repeat exams, increasing radiation exposure.

Therefore, the focus on only performing necessary imaging is a cornerstone of radiation safety practices designed to
