摘要目的 探讨不同类型的铅围脖在乳腺癌保乳术后放疗中对甲状腺的保护作用。 方法 40例乳腺癌保乳术后放疗患者随机分为4组，每组10例，分别使用0 mm Pb（对照组），0.5 mm Pb（普通材料组），2 mm Pb（普通材料组），2 mm Pb（新型防辐射材料组）铅围脖对甲状腺进行防护，监测铅围脖内外剂量，并进行统计学分析；通过问卷调查，获取对围脖接受程度等的结果，并进行分析。结果 除佩戴0 mm Pb（对照组）患者的铅围脖内外散射量差异无统计学意义外，0.5 mm Pb（普通材料组）、2 mm Pb（普通材料组）、2 mm Pb（新型防辐射材料组）差异均有统计学意义（P < 0.05），其中2 mm Pb（新型防辐射材料组）的散射量衰减均值33.64%明显优于其他各组（P < 0.05）。4组患者放疗结束后佩戴铅围脖处的皮肤颜色及外观均无明显改变，第一次复查甲状腺B超均正常，在接受程度方面，2 mm Pb新型防辐射材料铅围脖的可接受程度最高。结论 新型防辐射材料制成的铅围脖对甲状腺具有较好的保护作用，易被患者接受，建议推广使用。
