摘　　要：目的应用MR相关扫描序列对海绵窦综合征病例进行比较分析。方法 33例海绵窦综合征的患者分别行常规头颅MR平扫序列,海绵窦区薄层扫描FSE序列的T_1WI、T_2WI、STIR序列扫描,3D-FIESTA序列扫描,及FSE序列的T_1WI增强扫描,分析几组扫描序列对海绵窦综合征的显示情况。结果通过随访手术结果及临床治疗效果等与诊断进行对照分析,对于海绵窦综合征的病例不同扫描序列检出率分别为:常规的MR平扫序列可发现72.7%,海绵窦区薄层扫描可发现84.8%,3D-FIESTA序列可发现87.8%,T_1WI增强扫描可发现93.9%。结论常规头颅MR平扫序列对于海绵窦综合征有一定的漏诊率;海绵窦区薄层扫描及3D-FIESTA序列作为平扫序列对病变检出情况相差不大,且明显优于常规头颅MR平扫序列,但是3D-FIESTA序列对于病变性质的判定存在一定的困难;T_1WI增强扫描对于海绵窦病变综合征检出及定性情况最好,漏诊率最低。Objective To compare the value of different MR sequence on evaluating cavernous sinus syndrome. Methods Routine head MR scan sequence; thin slice scanning of cavernous sinus area with FSE T1WI, T2WI, STIR sequences, 3D-FIESTA sequence, enhanced FSE TIWI sequence were performed in 33 cases with cavernous sinus syndrome. And the display of cavernous sinus was analyzed. Results Detection rate of cavernous sinus syndrome was 72.7% with routine head MR scan, 84.8% with cavernous sinus thin slice scanning, 87.8% with 3D-FIESTA sequence and 93.9% with enhanced T1WI scan. Conclusion Routine MR head scan will miss diagnosis of cavernous sinus syndrome in some degree; cavernous sinus thin slice scanning and 3D-FIESTA sequence can detecte the lesions better and the best way in using enhanced T1WI scan to detect and characterize cavernous sinus syndrome.
