矢状面SPIR结合动态增强技术在子宫内膜癌分期中的价值

目的:探讨矢状面SPIR结合动态增强技术在子宫内膜癌分期中的价值。方法:85例经手术病理证实的子宫内膜癌患者均行MRI横断面T1WI、T2WI,矢状面T2WI SPIR、Gd-DTPA动态增强及常规横断面T1WI增强扫描,观察肿瘤、结合带及肌层侵犯情况,将矢状面SPIR结合动态增强与其它序列比较。结果:对明确肿瘤性质、判断子宫结合带中断及肌层侵犯,矢状面SPIR结合动态增强序列明显优于其它序列。结论:矢状面SPIR结合动态增强技术对子宫内膜癌术前分期有重要价值,应成为子宫内膜癌术前常规的一种检查技术。

Value of Sagittal SPIR Pulse Sequence MR Imaging with Dynamic Enhancement in Pre-operative Staging of Endometrial Carcinoma

Objective:To evaluate the role of sagittal SPIR (spectral presaturation with inversion recovery) pulse sequence with dynamic enhancement MRI technique in endometrial carainoma preoperative staging.(Methods:)85 cases of pathologically confirmed endometrial carcioma patients were studied retrospectively to assess the staging capability by MRI.Axial TSE T_1WI and T_2WI,sagittal TSE T_2WI and SPIR,sagittal and axial dynamic Gd-DTPA enhanced TSE T_1WI were used.Details of the tumor,involvement of junctional zone,muscular layer and structures adjacent to the tumor were observed on MR scans.The tumor staging capability of sagittal dynamic Gd-DTPA enhanced SPIR pulse with those of other pulse sequence techniques was comparatively assessed.Results:For showing tumor features of endometrial carcinoma,interruption of junctional zone and invasion of the muscular layer,sagittal dynamic enhanced SPIR pulse sequence was superior to other sequences.Conclusion:Sagittal dynamic enhanced SPIR pulse sequence was very useful for pre-operative staging of endometrial carcinoma,therefore,it might be recommended as a regular examination for pre-operative staging in endometrial carcinoma cases.
