[Abstract] Ischemic injury in brain is a very forward-looking clinical subject. In many clinical cases, we can see different degrees of ischemic damage in brain because of many reasons. In the past, we payed more attention to whether an infarction was happened or focused on imaging features of early cerebral infarction. However, we just ignore the predictive diagnosis and lesions outcome of cerebral ischemia as well as the preventive study in the side of ischemic injury during medical process. In this article, we analysis the ischemic injury caused by many reasons to arouse the macroscopic understanding of cerebral ischemic injury in another perspective. Cerebral ischemia is a systematic pathology process and a lot of causal relationship is not entirely clear that is both the contradiction and unity. We can see some MRI expression look similar to inflammatory lesions, edema and so on. The pathological process of cerebral ischemia is a process of processing and the changes of the central nervous system will evolve following the dynamic changes. Cerebral infarction is only a kind of ending form of ischemia while cerebral ischemia is the prelude of cerebral infarction. We meet varying degrees of ischemic brain injury for many reasons in our daily practice everyday and the cerebral ischemia which is not display in the form of infarction is frequently ignored by clinicians. This paper introduced a variety reason of cerebral ischemia and their respective MRI performance in typical cases form and discussed how to under stand the images correctly. We aim to move diagnosis and treatment time win dows forward and improve patients quality of life in future though predict the development of disease with the aid of imaging subtle changes and signs.
