肝脏介入操作所致患者辐射剂量的初步研究

Radiation Exposure to Patients During Hepatic Interventional Procedure

目的测量在肝脏介入操作过程中患者所受到的X射线的辐射剂量。方法应用热释光测量法、非均匀组织等效拟人体模型实验数据结合实际操作条件等方法,对85例行肝脏介入操作的患者进行辐射剂量测量。结果肝脏介入操作所致患者最高皮肤剂量范围为179.95～1759.00mGy,有效剂量为29.22mSv(男)和29.27mSv(女)。结论肝脏介入治疗患者所受到的X线辐射剂量很大,应该采取有效的防护措施来降低患者所受到的X线辐射剂量。

Objective To investigate the X-ray radiation dose patients dealt with the hepatic intervention.Methods Thermoluminescence and tissue-equivalent anthropomorphic phantom were used to measure the X-ray radiation dose in patients dealt with the hepatic intervention in 85 patients. [WTHZ]Results The peak skin dose in the patients who accepted hepatic intervention was from 179.95 to 1759.00 mGy,effective dose approached 29.22 mSv(male)、29.27 mSv(female). Conclusion Hepatic intervention is now regarded as an important therapeutic method for liver cancer.However,the patients were exposed to too much X-ray radiation during interventional procedures.Some more effective protection should be taken to decrease the X-ray radiation dose accepted by patients.
