Objective To explored the clinical value of contrast-enhanced ultrasound in assessment of the cura-tive effect in cervical carcinoma treated with 3-dimensional conformal radiation therapy (3DCRT). Methods Fifty pa-tients who were clinically diagnosed of cervical carcinoma in our hospital from 2013 to 2015 all underwent contrast-en-hanced ultrasound before and after 3DCRT. Then contrast-enhanced ultrasound parameters were recorded and compared. Results Compared with the parameters before 3DCRT, the sizes of cervical carcinoma [(47.4±5.1) mm vs (30.8±4.8) mm] and the peak intensities [(85.35±10.52) dB vs (56.51±9.83) dB] reduced significantly, and the beginning time of enhance-ment [(8.23±3.70) s vs (10.27±4.66) s], the time to peak intensities [(25.27±3.24) s vs (36.60±5.23) s], the beginning time of perfusion [(42.78 ± 8.15) s vs (52.47 ± 9.36) s], the time of complete perfusion [(95.81 ± 37.32) s vs (120.37 ± 24.55) s] were delayed. The differences were statistically significant (P<0.05). Conclusion Contrast-enhanced ultrasound has certain extent clinical value in the assessment of the curative effect of cervical carcinoma treated with 3DCRT.%目的：探讨超声造影技术对评价宫颈癌三维适形放疗疗效的临床价值。方法选取2013-2015年间在我院妇产科接受三维适形放疗50例宫颈癌患者，分别于治疗前后进行超声造影检查，记录超声造影参数并进行对比分析。结果与接受三维适形放疗前相比，放疗后宫颈癌病灶变小[(47.4±5.1) mm vs (30.8±4.8) mm]，超声造影峰值强度明显减低[(85.35±10.52) dB vs (56.51±9.83) dB]，开始增强时间[(8.23±3.70) s vs (10.27±4.66) s]、达峰时间[(25.27±3.24) s vs (36.60±5.23) s]、开始廓清时间[(42.78±8.15) s vs (52.47±9.36) s]、完全廓清时间延迟[(95.81±37.32) s vs (120.37±24.55) s]，差异均具有统计学意义(P<0.05)。结论利用超声造影技术对宫颈癌三维适形放疗疗效进行评价有一定临床价值。
