DATA RETRIEVAL： We performed a bibliometric analysis of data retrieval for neuroimaging diagnosis for cerebral infarction containing the key words ＂CT, magnetic resonance imaging, MRI, transcranial Doppler, transvaginal color Doppler, digital subtraction angiography, and cerebral infarction＂ using the Web of Science. SELECTION CRITERIA： Inclusion criteria were： （a） peer-reviewed articles on neuroimaging diagnosis for cerebral infarction which were published and indexed in the Web of Science; （b） original research articles and reviews; and （c） publication between 2004-2011. Exclusion criteria were： （a） articles that required manual searching or telephone access; and （b） corrected papers or book chapters. MAIN OUTCOME MEASURES： （1）Annual publication output; （2） distribution according to country; （3） distribution according to institution; （4） top cited publications; （5） distribution according to journals; and （6） comparison of study results on neuroimaging diagnosis for cerebral infarction. RESULTS： Imaging has become the predominant method used in diagnosing cerebral infarction. The most frequently used clinical imaging methods were digital subtraction angiography, CT, MRI, and transcranial color Doppler examination. Digital subtraction angiography is used as the gold standard. However, it is a costly and time-consuming invasive diagnosis that requires some radiation exposure, and is poorly accepted by patients. As such, it is mostly adopted in interventional therapy in the clinic. CT is now accepted as a rapid, simple, and reliable non-invasive method for use in diagnosis of cerebrovascular disease and preoperative appraisal. Ultrasonic Doppler can be used to reflect the hardness of the vascular wall and the nature of the plaque more clearly than CT and MRI. CONCLUSION： At present, there is no unified standard of classification of cerebral infarction imaging. Detection of clinical super-acute cerebral infarction remains controversial due to its changes on imaging, lack of specificity, and its similarity to a space-occupying lesion. Neuroimaging diagnosis for cerebral infarction remains a highly active area of research and development.展开更多

The result shows that electroacupuncture for acute cerebral infarction has remarkable cura tive effect (the remarkable effective rate was 82.9 %, and the total effective rate was 97.1 % ). Com bining with the CT analysis, the authors found that the condition of acute cerebral infarction patients and curative effect have close relation with the size and depth of fouses’ position (P<0.01 ).展开更多

Methods: A total of 148 patients who were treated in Maanshan Shiqiye Hospital between June 2014 and February 2017 due to vertebrobasilar artery stenosis were selected as the research subjects and divided into cerebral infarction group and transient ischemic attack (TIA) group according to the imageological examination. CTA was used to evaluate vertebrobasilar atherosclerotic plaque properties, and enzyme-linked immunosorbent assay kit was used to determine the levels of nerve injury markers, inflammatory response-related molecules and plaque property-related protease molecules. Results: The positive rate of posterior circulation plaque in cerebral infarction group was obviously higher than that in TIA group, and the positive rate of unstable plaque, fibrous plaque and calcified plaque were higher than those in TIA group;serum NSE, S100B, UCH-L1, GFAP, ICAM-1, VCAM-1, PECAM-1, VE-cadherin, YKL-40, CatS, MMP9, MMP10 and ADAMTS12 levels of cerebral infarction group of patients with unstable plaque, fibrous plaque and calcified plaque were all higher than those of TIA group;serum NSE, S100B, UCH-L1, GFAP, ICAM-1, VCAM-1, PECAM-1, VE-cadherin, YKL-40, CatS, MMP9, MMP10 and ADAMTS12 levels of cerebral infarction group of patients with unstable plaque and fibrous plaque were all higher than those of patients with calcified plaque, and serum NSE, S100B, UCH-L1, GFAP, ICAM-1, VCAM-1, PECAM-1, VE-cadherin, YKL-40, CatS, MMP9, MMP10 and ADAMTS12 levels of cerebral infarction group of patients with unstable plaque were all higher than those of patients with fibrous plaque. Conclusion: CTA can accurately assess the property of vertebrobasilar atherosclerotic plaque in patients with posterior circulation cerebral infarction and is closely related to the degree of nerve injury and the change of plaque property.展开更多

By CT perfusion imaging, 29 cases in the cerebral infarction group and 10 cases in the transient ischemic attack group presented with abnormal blood flow perfusion, which corresponded to the clinical symptoms. By CT angiography, various degrees of vascular stenosis could be detected in 41 patients, including 33 in the cerebral infarction group and eight in the transient ischemic attack group. The incidence of intracranial artery stenosis was higher than that of extracranial artery stenosis. The intracranial artery stenosis was located predominantly in the middle cerebral artery and carotid artery siphon, while the extracranial artery stenosis occurred mainly in the bifurcation of the common carotid artery and the opening of the vertebral artery. There were 34 cases （83%） with convict vascular stenosis and perfusion abnormalities, and five cases （45%） with perfusion abnormalities but without convict vascular stenosis. The incidence of cerebral infarction in patients with National Institutes of Health Stroke Scale scores 〉 5 points during onset was significantly higher than that in patients with National Institutes of Health Stroke Scale scores 〈 5 points. These experimental findings indicate that the combined application of various CT imaging methods allows early diagnosis of acute ischemic cerebrovascular disease, which can comprehensively analyze the pathogenesis and severity of acute ischemic cerebrovascular disease at the morphological and functional levels.展开更多

Systemic arterial air embolism causing cerebral infarction is a rare but much feared complication of percutaneous lung biopsy. We present a comprehensive review of iatrogenic air embolism post-lung biopsy, a complication that is often sub optimally managed.
