颅内动脉瘤的比较影像诊断学

Comparative diagnostic imageology of intracranial aneurysm

目的探讨不同的影像检查方法对脑动脉瘤的诊断意义,以发现最佳诊断方法。方法对247例动脉瘤患者行CT、DSA、MRI检查,其中男149例,年龄25-62岁;女98例,年龄27-62岁。发现阳性率分别为 71.25%、93.79%、93.57%。结论由于动脉瘤的大小、结构、部位及组织关系的不同,靠单一诊断均难完全确诊, 故应联合使用以利于提高动脉瘤及合并疾病的诊断率和治愈率。

Objective To explore diagnostic significance on different imaging examinations for intracranial aneurysm to find out the best diagnostic method. Methods 247 cases of intracranial aneurysm (149 cases are male patients aged between 25-62; 98 cases are female patients aged between 27-62) were examined by CT, DSA, MRI, and the positive rates are respectively 71. 25%, 93.79%, 93.57%. Conclusion Due to the differences of aneurysm’s size, structure, position and tissue relationship, any one of the methods can’t give correct diagnose independently. So the methods of examinations should be used together to improve diagnostic rate and cure rate of aneurysms and its complications.
