摘　　要：目的探讨MRI分期在子宫颈癌诊断和治疗中的临床意义。方法对我院妇科子宫颈活检证实的72例子宫颈癌患者于临床症状出现后行MRI检查。由二位MRI诊断医师分别对每例患者的图像资料进行分析记录,包括病灶的部位、大小、浆膜有否受累、是否侵及子宫旁、周围器官是否侵及和淋巴结肿大情况,并依据Sironi's提出的分期方法进行了MRI分期。根据MRI的分期结果,51例子宫颈癌接受了手术治疗,并将手术后病理分期结果与MRI的分期结果进行了比较。结果72例活检证实的子宫颈癌,MRI均发现了病灶。51例手术病例中,44例的MRI分期结果与术后病理分期结果相吻合。总的MRI分期的符合率为86.4%。结论对Ⅰa期以上的子宫颈癌,MRI均可以显示病灶,并可以进行合理分期。如把子宫颈癌的MRI分期合理应用于子宫颈癌的诊治,对其治疗方法的选择有重要意义。Objective To evaluate the clinic significance of MRI staging in the diagnosis and treatment of cervical carcinoma. Methods Seventy-two gynecologic inpatients with histopathologically proved cervical carcinoma underwent MR imaging after onset of clinical symptoms.All the patients whose MRI finding which comprised the involved location,extent,and whether occuring the invasion of serous membrane,parauterine tissue and organ or nodal swelling were recorded for each case by two radiologists with rich experience and staged according to Sironit＇s clasification. MRI staging in all patients was compared with that of postoperative pathology.Results MR images clearly showed the lesions of cervical carcinoma in all patients.Among 51 patients who underwent surgery,44 patients whose MRI staging was corresponding to that of postoperative pathology.The total coincident rate was 86.4%.Conclusion The lesions of cervical carcinoma over and above Ia term can be fully visualized on MR images and can be reasonably staged.The reasonable application of MRI staging in the diagnosis and treatment has important significance to select the optimal therapeutic protocol.
