目的 探讨经阴道彩色多普勒超 声(TVCDS)、MRI单用或联用于宫颈癌术前 分期诊断临床价值差异。方法 回顾性分 析我院近期收治经术后病理确诊宫颈癌患 者共120例TVCDS和MRI影像学检查资料， 比较两种影像学方式单用、联用术前分期 与术后临床分期一致率。结果 MRI单用 于宫颈癌术前分期与术后临床分期一致 率为87.50%(105/120)；TVCDS单用于宫 颈癌术前分期与术后临床分期一致率为 85.00%(105/120)；两种影像学方式联用 于宫颈癌术前分期与术后临床分期一致率 为92.50%(111/120)；两种影像学方式联 用于宫颈癌术前分期与术后临床分期一致 率显著高于MRI、TVCDS单用，差异有统计 学意义(P＜0.05)。结论 TVCDS与MRI联用 可有效提高宫颈癌术前分期诊断准确程 度，价值优于TVCDS、MRI单用。

Objective To investigate clinical value differences of preoperative staging diagnosis of cervical cancer by MRI and TVCDS used alone and combination. Methods The imaging data of MRI and TVCDS of 120 patients with cervical cancer by operation diagnosis were retrospectively analyzed and the diagnosis consistent rate of patients with cervical cancer by MRI and TVCDS used alone and combination between preoperative staging and postoperative staging was compared. Results The diagnosis consistent rate of patients with cervical cancer by MRI used alone between preoperative staging and postoperative staging was 87.50%(105/120), the diagnosis consistent rate of patients with cervical cancer by TVCDS used alone between preoperative staging and postoperative staging was 85.00%(105/120), the diagnosis consistent rate of patients with cervical cancer by MRI combined with TVCDS between preoperative staging and postoperative staging was 92.50%(111/120). The diagnosis consistent rate of patients with cervical cancer by MRI combined with TVCDS between preoperative staging and postoperative staging was significant higher than MRI and TVCDS used alone (P>0.05). Conclusion Compared with MRI and TVCDS used alone, MRI combined with TVCDS in preoperative staging diagnosis of cervical cancer possesses higher accuracy.
