薄层斜轴位T2WI扫描在判断子宫恶性肿瘤宫颈浸润范围中的价值

目的 探讨薄层斜轴位扫描在判断子宫恶性肿瘤宫颈浸润范围中的价值. 资料与方法 回顾性分析53例经手术病理证实的子宫恶性肿瘤患者的MRI资料,比较普通轴位、旁矢状位及薄层斜轴位T2WI 3种扫描方法对判断子宫恶性肿瘤宫颈浸润范围的准确性. 结果 普通轴位、旁矢状位和薄层斜轴位T2WI判断宫颈病变浸润范围的准确性分别为77.36%、60.38%和92.45%.普通轴位与旁矢状位相比（χ2=3.56,P＞0.05）,两者之间差异无统计学意义;薄层斜轴位与旁矢状位比较（χ2=15.13,P＜0.05）,两者之间差异有统计学意义.薄层斜轴位与普通轴位比较（χ2=4.71,P＜0.05）,两者之间差异有统计学意义. 结论 对于宫颈病变浸润程度和范围的准确评价,薄层斜轴位扫描是一种非常必要而且有用的方法,应在常规轴位扫描的基础上加扫薄层斜轴位,提高宫颈病变浸润程度和范围判断的准确性.

The Value of Thin Section Oblique Axial T2WI Images for Evaluating Cervical Invasion by Malignant Uterine Tumors

Objective To discuss the value of thin-section oblique axial T2WI images for evaluating cervical invasion by malignant uterine tumors. Materials and Methods The MR data of 53 cases with malignant uterine tumors confirmed by pathology were analyzed retrospectively, the accuracy for evaluating cervical invasion by routine axial, para-sagittal and thin-section oblique axial T2WI images was compared. Results The accuracy rate of routine axial, para-sagittal and thinsection oblique axial T2WI images for evaluating the cervical invasion was 77.36% ,60.38% ,92.45% respectively. There was no statistical significant difference in detecting the extent of cervical invasion between routine axial and para-sagittal, there was distinct statistically significant difference between routine axial, para-sagittal and thin-section oblique axial imaging. Conclusion The thin-section oblique axial T2WI image is a essential and useful method in evaluating the cervical invasion, the thin-section oblique axial T2WI should be performed in addition to routine axial T2-weighted images.
