CT exams account for what percentage of the effective dose in diagnostic radiologic procedures?

The correct answer indicates that CT exams account for approximately 67% of the effective dose in diagnostic radiologic procedures. This statistic underscores the significant contribution that computed tomography makes to the overall radiation exposure of patients undergoing diagnostic imaging.

CT examinations use ionizing radiation to produce detailed images of the body's internal structures, and the amount of radiation typically administered during these scans is higher compared to conventional X-rays. As a result, when considering the collective radiation dose from various diagnostic procedures, CT scans represent a substantial proportion of the total effective dose.

Understanding this statistic is crucial for healthcare professionals as it highlights the importance of ensuring that CT scans are used judiciously and only when necessary, taking into account the benefits versus the risks of increased radiation exposure. This awareness informs practices around patient safety, appropriate use of imaging, and informed consent processes.
