What is the purpose of documenting entrance skin exposure (ESE) after radiographic examination?

• A. To determine film processing time
• B. To evaluate image contrast
• C. To assess patient radiation dose for risk assessment and follow-up
• D. To monitor patient motion during imaging

Answer: (C)

Documenting entrance skin exposure provides a record of the dose delivered to the patient’s skin during the radiographic exam. This dose information is essential for assessing the patient’s overall radiation burden, enabling risk assessment and guiding follow-up if cumulative exposure appears high or if a previous study showed elevated doses. It supports dose optimization efforts, helping clinicians adjust technique to minimize exposure while still obtaining diagnostic-quality images. This metric is not used for film processing timing, image contrast determination, or monitoring patient motion during the study.
