Summary
Radiation exposure for medical staff during femorocerebral angiograms is safe. However, patient radiation doses are significant, necessitating methods to reduce exposure to sensitive areas.
Area of Science:
- Medical Physics
- Radiology
- Radiation Protection
Background:
- Femorocerebral angiograms utilize X-rays, posing potential radiation risks.
- Accurate radiation dosimetry is crucial for evaluating exposure levels in medical procedures.
Purpose of the Study:
- To measure radiation exposure on medical personnel and patients during femorocerebral angiograms.
- To assess the significance of patient radiation doses to radiosensitive areas.
- To propose methods for reducing patient radiation exposure.
Main Methods:
- Utilized Lithium Fluoride (LiF) thermoluminescent dosimeters for X-ray exposure measurement.
- Conducted dosimetry on angiographers, X-ray technicians, and patients during 18 procedures.
- Placed dosimeters on various body areas to capture localized exposure data.
Main Results:
- Radiation exposure for medical personnel was within permissible dose limits.
- Significant radiation exposure levels were detected in radiosensitive patient areas.
- The study quantified X-ray exposure during this specific angiographic procedure.
Conclusions:
- While medical staff exposure is controlled, patient radiation safety requires attention.
- Current femorocerebral arteriogram protocols may lead to significant patient radiation doses.
- Further investigation and implementation of dose reduction strategies are recommended for patients.
