CT血管造影联合单光子发射计算机断层扫描在短暂性脑缺血发作诊断中的价值

Diagnostic value of CT angiography combined with single-photon emission computed tomography on transient ischemic attack

目的探讨CT血管造影(CTA)联合单光子发射计算机断层扫描(SPECT)在短暂性脑缺血发作(TIA)诊断中的价值。方法54例患者于TIA末次发作后3 d内同日行头颈部CTA和SPECT检查,对CTA和SPECT检查进行分析。结果54例TIA患者中32例(59.26%)CTA检查显示相应供血动脉狭窄,动脉粥样硬化6例(11.11%)。54例TIA患者的脑SPECT灌注显像中43例(79.63%)发现与发作期临床表现一致的低灌注区,其中包括13例CTA图像正常的患者。结论CTA联合SPECT对TIA的病因诊断、治疗方案的确定以及预后估计有重要价值。

Objective To evaluate the diagnosis value of CT angiography（CTA） combined with single photon emission computed tomography（SPECT） transient ischemic attack（TIA）. Methods Fifty-four patients with TIA were examined by CTA and SPECT at the same time when 3 days after the last stroke, then the results were analyzed. Results Among 54 cases, the corresponding feeding arteries were stenotic in 32 cases and artherosclerosis in 6 cases by CTA. SPECT revealed the hypoperfusion area coherented with clinical manifestation of period of onset in 43cases, included 13 cases which CTA displayed normal. Conclusion It has important value of combining CTA with SPECT on TIA.
