1. Indications

Medical physics dose evaluation is indicated in specific scenarios where there is a concern regarding excessive radiation exposure. The following conditions warrant the use of this evaluation:

• Exceeding Institutional Review Threshold This evaluation is performed when a patient's radiation exposure surpasses the established limits set by the healthcare institution, necessitating a thorough assessment.
• Interventional Radiology Procedures The service is particularly relevant following interventional radiology procedures, where multiple imaging projections or sequences may lead to increased radiation exposure.
• Peak Dosage Calculation Request A peak dosage calculation is requested to ensure that the radiation dose administered is within safe and acceptable levels for the patient.

2. Procedure

The procedure for medical physics dose evaluation involves several critical steps to ensure accurate assessment and reporting of radiation exposure. Each step is essential for determining the safety and appropriateness of the radiation dose received by the patient.

• Step 1: Review of Patient History The radiation physicist begins by reviewing the patient's medical history and the specific interventional radiology procedures performed. This includes understanding the context of the procedures and any previous radiation exposure the patient may have had.
• Step 2: Assessment of Radiation Exposure The physicist then assesses the radiation exposure by analyzing the imaging data collected during the procedures. This involves calculating the total dose received by the patient and comparing it against the institutional review threshold.
• Step 3: Peak Dosage Calculation A peak dosage calculation is performed to determine the maximum radiation dose the patient was exposed to during the imaging sequences. This calculation is crucial for identifying any potential risks associated with the exposure.
• Step 4: Documentation and Reporting Finally, the findings from the evaluation are documented in a detailed report. This report includes the results of the assessment, the peak dosage calculation, and any recommendations for future imaging or monitoring of the patient’s radiation exposure.

3. Post-Procedure

After the medical physics dose evaluation is completed, the radiation physicist provides the report to the referring physician. This report serves as a critical tool for ongoing patient management and safety. The physician may use the findings to make informed decisions regarding future imaging procedures and to discuss any necessary precautions with the patient. Additionally, the evaluation may prompt further monitoring of the patient's radiation exposure in subsequent procedures to ensure that it remains within safe limits. It is essential for healthcare providers to maintain open communication with patients regarding their radiation exposure and any implications for their health.
