目的探讨单光子发射计算机断层/X线计算机断层扫描(SPECT/CT)在脑梗死失语症的定位及定性诊断中的意义。方法 26例经磁共振成像(MRI)诊断为脑梗死的患者按有无失语分为两组,行SPECT/CT脑血流灌注断层显像,采用感兴趣区(ROI)技术进行局部脑血流定量分析。结果 SPECT/CT可准确检出脑梗死病灶,对病灶范围的显示比MRI更广泛;脑梗死伴失语症与MRI定位有关,但SPECT定位更准确;局部脑血流灌注量的降低程度与失语症关系密切(P<0.01)。结论 SPECT/CT可探查到脑血流及功能损伤和形态学改变,对失语症的临床诊断有参考意义。
Objective To investigate the significance of single photon emission computed tomography / computed tomography (CT) in the localization and qualitative diagnosis of cerebral infarction aphasia. Methods Twenty-six patients diagnosed as cerebral infarction by magnetic resonance imaging (MRI) were divided into two groups according to the presence or absence of aphasia. SPECT / CT perfusion tomography was performed. Regional cerebral blood flow (ROI) Quantitative analysis. Results SPECT / CT could detect the cerebral infarction accurately and show the range of the lesions more extensively than MRI. The cerebral infarction with aphasia was related to the MRI localization, but the SPECT localization was more accurate. The reduction of the local cerebral blood flow perfusion and the aphasia Close relationship (P <0.01). Conclusion SPECT / CT can detect cerebral blood flow and functional injury and morphological changes, and has clinical significance for the clinical diagnosis of aphasia.
