摘要 目的:探讨磁共振弥散加权成像技术在预测宫颈癌放射敏感性中的应用价值。方法:选取2009年4月至2015年1月初诊为宫颈癌患者90例,进行单纯放疗,分别测定患者在放疗前、放疗20 GY时与放疗结束时的磁共振弥散加权成像图像,进而测定患者宫颈癌原发灶的表观弥散系数(apparent diffusion coefficient,ADC)值。结果:在放疗前,患者的ADC值为(0.93±0.14)×10-3mm2/s、在放疗20 GY时,患者的ADC值为(1.25±0.17)×10-3mm2/s、在放疗结束时,患者的ADC值为(1.55±0.13)×10-3mm2/s,三者之间比较差异有统计学意义(P<0.05)。结论:放疗后宫颈癌原发灶的ADC值将会明显升高,通过磁共振弥散加权成像技术可对宫颈癌放射敏感性做出较好的预测。
