| 摘 要： | 目的探讨3D-TOFMRA与MRI联合应用在颅内动脉瘤中的诊断价值。方法选择经DSA证实为颅内动脉瘤且资料齐全的18例患者,回顾性分析其MRA、MRI资料。MRA采用三维时间飞跃法(3D-TOF),MRI采用SET1WI、T2WI成像。结果 18例患者共计21个病灶,3D-TOFMRA显示19个病灶,MRI显示17个病灶,3D-TOFMRA联合MRI则全部显示病灶并确诊。结论 3D-TOFMRA与MRI联合应用可极大地提高颅内动脉瘤的发现率及确诊率。

| Abstract: | Objective To assess the Evaluation of 3D-TOF MRA combined with MRI in the diagnosis of intracranial aneurysms. Methods 18 cases of intracranial aneurysms were confirmed by digital subtraction angiography（DSA）,To retrospectively analyze the MRA and MRI information. MRA was done with 3D-TOF sequences and MRI was performed with SE TI and T2 weighted suquences. Results 21 aneurysms were proved by in 18 cases, 19 aneurysms were found on 3D-TOF MRA,17 aneurysms were found on MRI, all aneu- rysms were found on 3D-TOF MRA combined with MRI. Conclusion 3D-TOF MRA combined with MRI may improve the diagnostic accuracy. |
