How is patient dose from diagnostic X-rays most commonly reported, given its ease of measurement?

The most commonly reported patient dose from diagnostic X-rays is entrance skin exposure. This measurement is particularly valued because it is straightforward to assess and provides a clear indication of the radiation dose received by the skin at the entry point of the X-ray beam. Entrance skin exposure represents the amount of radiation absorbed by the skin, which is significant for evaluating the immediate risk of radiation effects, like skin burns or other radiation-related injuries, particularly in the context of repeated imaging.

This method of reporting is preferred in many clinical settings due to its practical application and the direct correlation it has with the radiation dose that patients receive during X-ray procedures. Monitoring entrance skin exposure helps healthcare providers make informed decisions about the safety and appropriateness of diagnostic imaging, ensuring that patient exposure is minimized while still obtaining necessary diagnostic information. Other metrics, while important in specific contexts, do not lend themselves as readily to routine measurement or assessment in the same way.
