To identify global research trends in neuroimaging diagnosis for cerebral infarction using a bibliometric analysis of the Web of Science.
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.
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.
(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.
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.
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.
利用科学引文索引（Web of Science）的文献计量学分析，确定脑梗死神经影像学诊断的全球研究趋势。
我们使用科学引文索引对包含“CT、磁共振成像、MRI、经颅多普勒、经阴道彩色多普勒、数字减影血管造影和脑梗死”等关键词的脑梗死神经影像学诊断数据进行了文献计量学分析。
纳入标准为：（a）发表并在科学引文索引中索引的脑梗死神经影像学诊断的同行评审文章；（b）原始研究文章和综述；（c）发表于 2004-2011 年之间。排除标准为：（a）需要手动搜索或电话访问的文章；（b）更正后的论文或章节。
（1）年度出版物输出；（2）按国家分布；（3）按机构分布；（4）高被引出版物；（5）按期刊分布；（6）脑梗死神经影像学诊断的研究结果比较。
影像学已成为诊断脑梗死的主要方法。最常用的临床影像学方法是数字减影血管造影、CT、MRI 和经颅彩色多普勒检查。数字减影血管造影作为金标准。然而，它是一种昂贵且耗时的有创诊断方法，需要一定的辐射暴露，并且患者接受度较差。因此，它主要在临床介入治疗中采用。CT 现在被认为是一种快速、简单、可靠的非侵入性方法，用于诊断脑血管疾病和术前评估。超声多普勒比 CT 和 MRI 更能清晰地反映血管壁的硬度和斑块的性质。
目前，脑梗死影像学分类尚无统一标准。由于其影像学变化、缺乏特异性以及与占位病变的相似性，对临床超急性脑梗死的检测仍存在争议。脑梗死的神经影像学诊断仍然是一个非常活跃的研究和开发领域。
