目的:评价热成像对颈内动脉脑梗死的辅助诊断价值.方法:利用BPM-Ⅰ型电调焦HTI功能诊断仪对36例颈内动脉脑梗死、30例正常对照及14例其他神经系统疾病患者进行检查,并做比较.结果:32例(88.9%)脑梗死患者的病变侧有冷区表现,而正常对照组中仅有4例(13.3%)出现冷区,两组经统计处理有显著性差异,P<0.001.结论:热成像对颈内动脉脑梗死有一定的辅助诊断价值.特别在梗死的早期,热成像可能较CT能更早地反映脑缺血的状态.
Objective: To evaluate the value of thermal imaging in the diagnosis of cerebral infarction of internal carotid artery.Methods: Thirty-six cases of internal carotid artery infarction, 30 normal controls and 14 other neurological diseases Patients were examined and compared.Results: Cold lesions were found in 32 patients (88.9%) with infarction and only 4 (13.3%) in normal control group, and the two groups were statistically (P <0.001) .Conclusion: Thermal imaging may be helpful in diagnosing ICA.It is suggested that thermal imaging may reflect the status of cerebral ischemia earlier than CT in early stage of infarction.
