摘要: 目的 分析放射介入治疗肝癌患者接受的辐射剂量。方法 261例肝癌患者分为肝叶超选择介入组和肝段超-超选择介入组,分析随机记录的辐射参数。结果 介入治疗患者接受的透视时间为(9.67±6.44)min、造影次数(4.29±1.68)次、造影时间为(48.3±19.1)s、面积剂量乘积(dose area product,DAP)为(29531±10798)μGym2、有效剂量(effective dose,ED)为(4.43±1.62)mSv、累积剂量(cumulative dose,CD)为(1029.6±526.8)mGy、最高皮肤剂量(peak skin dose,PSD)为(864.9±442.5)mGy。肝段超-超选择组的透视时间、造影次数、造影时间、DAP、ED、CD和PSD均高于肝叶超选择组。117例(44.8%)患者的CD值>1 Gy。结论 接受放射介入治疗的肝癌患者接受了较高剂量的辐射,术者应优化数字减影血管造影参数减少辐射剂量。

Abstract: Objective To analyze the radiation dose received by patients with liver cancer undergoing radiation interventional therapy. Methods 261 cases of liver cancer were divided into hepatic lobe superselective intervention group and liver segment super-superselective interventional group. The recorded radiation parameters on the instrument were analyzed. Results The fluoroscopy time was (9.67±6.44) min, number of angiography was (4.29±1.68) times, angiography time was (48.3±19.1) s, dose area product (DAP) was (29531±10798) μGym2, effective dose (ED) was (4.43±1.62) mSv, cumulative dose (CD) was (1029.6±526.8) mGy, peak skin dose (PSD) was (864.9±442.5) mGy. The fluoroscopy time, number of angiography, angiography time, DAP, ED, CD and PSD in the liver segment super-superselective group were higher than those in the hepatic lobe superselective group. 117 patients(44.8%) had CD values greater than 1Gy. Conclusion Patients with liver cancer who undergone radiation interventional therapy received a higher dose of radiation. The surgeon should optimize the DSA parameters to reduce the radiation dose the patients received.
