磁共振扩散加权成像序列在卵巢囊腺类肿瘤诊断中的应用探讨

目的：观察磁共振扩散加权成像（DWI）以及表观扩散系数（ADC）在卵巢良恶性囊腺类肿瘤诊断的应用情况并探讨其诊断价值。材料和方法：对52例72个病灶的各类囊腺类肿瘤进行MRI检查及通过DWI序列检测感兴趣区的ADC值，并进利用统计软件进行定量分析。结果：不同性质的卵巢肿瘤其ADC值不同。各种不同性质卵巢肿瘤的ADC值部分存在显著的统计学差异。结论：DWI对卵巢囊腺类肿瘤的鉴别诊断具体有一定的价值，有助于良恶性及部分病理类型肿瘤的鉴别。

Duffusion Weighted Imaging in Ovarian Cystadenomatous Tumors

Objective： To investigate the value of duffusion weighted imaging（DWI） and apparent diffusion coefficient（ADC） in the diagnosis of ovarian cystadenomatous tumours. Methods： Magnetic resonance imaging including DWI was performed in 52 patients with 72 histopathologically proved ovarian cystadenomatous tumours. ADC values of cystic components and solid components in benign and malignant ovarian cystadenomatous tumours were compared and analyzed by SPSS 13.0. Results： The average ADC values of different ovarian turnouts are different, and there exist significant differences among the different types of ovarian turnouts. Conclusion ： DWI can provide useful messages in the diagnosis and identification of ovary cystadenomatous tumours, especially in bengin and malignant tumours and some pathologic types of ovarian tumours.
