摘要
目的探讨磁共振增强三维双激发平衡式自由稳态进动(contrast-enhanced three-dimensional fast imaging employing steady-state acquisition with phase cycling,CE 3D-FIESTA-C)序列评价垂体大腺瘤与颅神经(cranial nerves,CNs)海绵窦段关系的价值.材料与方法前瞻性收集40例垂体大腺瘤患者,所有患者均行CE 3D-FIESTA-C和增强三维容积(contrast-enhanced brain volume,CE BRAVO)序列扫描,统计每例患者双侧海绵窦内CNs的显示率.结果在CE 3D-FIESTA-C序列上,第Ⅲ~Ⅵ对颅神经(CNⅢ、Ⅳ、Ⅴ1、Ⅴ2、Ⅵ)海绵窦段的显示率分别为75.0%、25.0%、71.3%、71.3%、41.3%,显示率均高于CE BRAVO序列(P<0.01).在CE 3D-FIESTA-C序列冠状位上,以颅神经因肿瘤影响中断或未显示判定同侧海绵窦受侵,诊断的敏感性和特异性分别为41.7%和95.8%.结论CE 3D-FIESTA-C序列能较好地显示垂体大腺瘤患者CNⅢ~Ⅵ海绵窦段,通过观察CNⅢ~Ⅵ海绵窦段是否因肿瘤影响中断或未显示,可辅助诊断同侧海绵窦是否受侵.
Objective:To evaluate the relationship between pituitary macroadenomas and cranial nerves in the cavernous sinuses by contrast-enhanced three-dimensional fast imaging employing steady-state acquisition with phase cycling(CE 3D-FIESTA-C).Materials and Methods:Forty patients with pituitary macroadenomas were prospectively collected,all of whom scanned the CE 3D-FIESTA-C and contrast-enhanced brain volume(CE BRAVO)sequence,and the display rate of cranial nerves in bilateral cavernous sinus was calculated for each patient.Results:On CE 3D-FIESTA-C sequence,the display rate of cranial nerves in the cavernous sinuses was 75.0%,25.0%,71.3%,71.3%,41.3%,respectively,which was higher than CE BRAVO sequence(P<0.01).On the CE 3D-FIESTA-C sequence,the cranial nerves at the tumor site was interrupted or not shown due to the influence of the tumor to determine the invasion of the ipsilateral cavernous sinus,and the sensitivity and specificity of diagnosis were 41.7%and 95.8%,respectively.Conclusions:The CE 3D-FIESTA-C sequence can better display the cranial nerves in the cavernous sinuses in patients with pituitary adenoma.By observing whether the cranial nerve in the cavernous sinuses is interrupted or not displayed due to the influence of tumor,it can assist the diagnosis of whether the ipsilateral cavernous sinus is invaded.
