目的：通过CTA检查结果与MRA检查结果的对比分析，探讨二者在诊断颅内动脉瘤中的临床应用价值。材料与方法回顾性分析60例高度怀疑颅内动脉瘤患者的DSA影像资料，及其CTA或MRA图像，在60例行DSA检查患者中，行CTA检查者30例，行MRA检查者30例。图像后处理采用最大密度投影(MIP)和容积重建(VR)，以DSA检查结果及行动脉夹闭术作为诊断动脉瘤的标准，比较CTA和MRA对颅内动脉瘤的显示情况。结果在60例中，DSA和动脉瘤夹闭术共证实30个动脉瘤，其中30例16个动脉瘤CTA显示良好，30例14个动脉瘤MRA显示良好。CTA发现颅内动脉瘤的敏感性为93.3%特异性为86.7%准确性为90.0%，MRA发现颅内动脉瘤的敏感性为60.0%特异性为66.7%准确性为63.3%。结论头颈部CTA检查能够快速、安全、无创、有效的诊断脑动脉瘤，可作为临床筛查大部分颅内动脉瘤的首选检查方法。

Objectives: To explore the clinical value of CTA and MRA in diagnosis of intracranial aneurysms by contrast analysis of CTA and MRA examination.Materials and Methods:A retrospective study was conducted by reviewing the DSA, CTA or MRA images records of 60 patientswith suspected intracranial aneurysms. For the 60 patients, 30 patients with CTA and 30 patients with MRA examination. Image post-processing methods include maximum intensity projection (MIP) and volume rendering (VR). DSA diagnosis and arterial aneurysm clipping surgery were regarded as diagnostic criterion for aneurysm to compare the ability of CTA and MRA for intracranial aneurysms manifestation.Results:In 60 cases, a total of 30 aneurysms were conifrmed by DSA and surgery, including 16 of 30 aneurysms showed by CTA, and 14 of 30 aneurysms showed by MRA. The sensitivity, speciifcity, and accuracy of CTA in intracranial aneurysms diagnosis were 93.3%, 86.7%, and 90.0% respectively. For MRA, the sensitivity, speciifcity, and accuracy in intracranial aneurysms diagnosis were 60.0%, 66.7%, and 63.3% respectively.Conclusions:CTA examination is a fast, safe, and non-invasive method for the effective diagnosis of cerebral aneurysms, and could be the optimal examination for clinical screening of intracranial aneurysms.
