How do motion artifacts influence radiation exposure during imaging?

Motion artifacts can significantly impact the quality of imaging results, often leading to images that are not interpretable. When images are compromised due to motion, healthcare providers may need to repeat the imaging procedure to obtain clear and accurate results. Each time an imaging study is repeated, there is an associated increase in radiation exposure to the patient. Therefore, the presence of motion artifacts generally correlates with a higher likelihood of requiring additional imaging, which ultimately raises the total amount of radiation received by the patient.

In contrast, the other options do not accurately reflect the relationship between motion artifacts and radiation exposure. Reducing the need for additional imaging or minimizing radiation dose contradicts the reality that motion artifacts lead to the necessity of repeat scans. Additionally, indicating that motion artifacts have no effect on radiation exposure overlooks the direct impact that repeat imaging has on patient safety and exposure levels.
