摘　　要：目的探讨磁共振成像不同序列对颅内海绵状血管瘤诊断的临床应用价值。方法应用磁共振梯度回波FLASH T2WI及自旋回波序列SE T1WI、T2WI对36例颅内海绵状血管瘤病人进行扫描,分析MRI不同扫描序列图像特征。结果36例病人中SE T1WI发现海绵状血管瘤病灶31个,SE T2WI发现病灶36个,FLASH T2WI发现病灶38个。结论在显示颅内海绵状血管瘤方面,MR梯度回波FLASH T2WI较SE序列更为优越。Objective To investigate the applied value of different MRI sequences in diagnosing intracranial cavernous hemangioma （CH）. Methods 36 cases with intracranial CH underwent MR GRE FLASH and T2WI sequence,SE T1WI and T2WI sequence examination. MRI features of CH at different sequences were analysed. Results Of 36 cases , 31 CH lesions were detected with SE T1WI , 36 CH lesions were detected with SE T2WI, 38 CH lesions were detected with FLASH T2WI. Conclusion MR GRE FLASH T2WI sequence is better than SE sequence in showing intracranial CH, and can provide some valuable diagnostic informations for clinical surgical treatment of radiation.
