Research Progress of Clinical Applications of Susceptibility-weighted Imaging for Cerebral Infarction

Cerebral infarction is one of the serious diseases endangering the health of the elderly,while early diagnosis and effective treatment have important significance on prognosis.Susceptibility-weighted imaging(SWI)can show the cerebral veins and hemorrhage within the lesion clearly,with especially obvious advantage in detection of micro-bleeding.The SWI can offer more valuable information for the diagnosis of cerebral infarction.Here is to make a review on the clinical application of SWI sequence in terms of reflecting the evolution of cerebral infarction,showing blood clot in the brain,detecting the hemorrhagic infarction,evaluating the activity of tissues surrounding cerebral infarction,pointing out the advantages and disadvantages of SWI technology in the applications of the cerebral infarction.
