【摘要】 目的 加深对宫颈癌螺旋CT表现的认识，探讨宫颈癌的螺旋CT诊断要点、分期及临床应用价值。方法 回顾性分析56例经手术病理证实或病理活检证实的宫颈癌螺旋CT表现及放疗后改变。结果 其中鳞癌49例、腺癌7例。Ⅰb～Ⅱa期患者29例，行子宫全切除、加盆腔淋巴结清扫;Ⅱb期患者21例，行介入局部动脉化疗后，再行手术根治;Ⅲ～Ⅳ期患者6例，未手术、行放疗加化疗。结论 螺旋CT能显示宫颈和宫体的动脉期及静脉期强化时相，改善血管强化效果，利于癌肿血供情况的观察和显示癌肿的实际范围;获得连续的薄层图像;能从横断面、矢状面及冠状面显示宫颈形态改变，辨别宫旁结构，阴道受侵及盆腔淋巴结、盆壁转移征象，对宫颈癌的分期准确，了解术后有无复发及放疗效果。但对部分Ⅰa期病例无法显示宫颈癌确切部位，早期宫颈癌仍需结合病理组织活检确诊。

    【Abstract】 Objective Strengthens the understanding to the cervical carcinoma that is displayed by the spiral CT，probes into the main point of cervical carcinoma diagnosing，by stages and clinical using value.Methods Analˉyses56patients with cervical carcinoma confirmed through pathology verification and pathology changed after the raˉdiotherapy by the spiral CT.Results Among them，there are49cases of squama cancer and7cases of adenocarcinoˉma.There are29patients withⅠb～Ⅱa cancer to have been performed the operation of uterus excising and pelvis lymph clear-out;there are21patients withⅡb cancer had been performed the operation that effects a radical cure after getting involved in the local artery chemotherapy;there are6patients withⅢ～Ⅳcervical carcinoma who had been performed the radiotherapy and chemotherapy without the operation.Conclusion The spiral CT can display the time phase strengthening of the artery and vein of uterus neck and its body ......
