摘　　要：目的探讨MRI定位子宫宫颈内口方法.方法回顾性收集因Ⅰa期子宫内膜癌行子宫切除术患者资料,所有患者术前行MRI检查.以大体病理为标准,方差分析法比较MRI图像3种方法测量宫颈长度是否与大体病理相同.T2 WI图像测量宫颈间质长度;以动态增强扫描图像宫体、宫颈强化差异形成截面测量宫颈长度;以子宫生理弯曲形成截面测量宫颈长度.结果大体病理宫颈长度(2.71±0.52)cm,以宫颈间质长度为准测量宫颈长度约(2.75±0.50)cm,以子宫生理弯曲为准测量宫颈长度约(2.73±0.45)cm,以动态增强扫描强化差异截面为准测量宫颈长度约(2.75±0.46)cm.方差分析结果显示4组宫颈长度差异无统计学意义(F=0.04,P=0.99).结论MRI图像3种方法测量宫颈长度结果与大体病理相同,可间接用于定位宫颈内口.Objective To investigate the method of MRI in locating the internal os of uterine cervix.MethodssThepatients of endometrial cancer with stageⅠa undergoing hysterectomy were retrospectively collected,and all patients underwent MRI before surgery.Gross pathology was used as standard,the three methods of measuring cervical length in MRI images were compared by variance analysis to see if there were different with the gross pathology.The length of the cervical stroma was measured in T,WI image;the length of the cervix was measured from the cross-section by the different enhancement of uterine body and cervix in the dynamic enhancement image;the length of the cervix was measured from the cross-section by the physiological curvature of the uterus.Results The cervical length of the gross pathology was(2.71±0.52)cm,and it was(2.75±0.50)cm based on the length of the cervical stroma,and it was(2.73±0.45)cm based on the physiological curvature of the uterus,and it was(2.75±0.46)cm based on the cross-section by the different enhancement of dynamic enhancement scan.There was no significant difference in cervical length among the four groups(F=0.04,P=0.99).Conclusion The results of cervical length measured with the three methods in MRI images are the same as gross pathology,which can be indirectly used to locate the internal cervical os.
