Abstract:
Magnetic resonance imaging has developed from a single observation of organisms’ anatomy and the change of morphology under the physiological and pathological conditions to the study of biology function and activity mechanism. Furthermore, it has entered into the molecular imaging and functional magnetic resonance imaging (fMRI), and diffusion-weighed imaging (DWI) is one of them, which is mainly used in the early diagnosis of cerebral infraction. This article elaborates diffusion-weighed imaging,the identification of acute and non-acute cerebral infarction by DWI in physiological basis of pathogenesis and the time vale of DWI examination. The author holds the opinion that it is of great significance to distinguish between acute and non-acute cerebral infarction by using DWI and that clinicians may adopt targeted therapies according to the different periods of cerebral infarction in order to avoid unsafe and unnecessarily risky treatments.
