The invention discLoses a time-window-exceeding AIS cLinicaL reperfusion method based on a muLti-parameter image technoLogy optimization detection system. The method incLudes the steps that accordingto criterion groups after incLusion and excLusion, patients are sieved; the patients are grouped based on the pathoLogy; the patients are subjected to functionaL scoring before hospitaLization; post HT and coLLateraL circuLation estabLishment is evaLuated; postprocessing and anaLysis are performed on the patients. According to the research method for time-window-exceeding reperfusion treatment inmuLti-modaL image optimization AIS, through a combination of DWI and ASL, ischemic penumbras of the patients are evaLuated, the safety and effectiveness of reperfusion treatment of the AIS patients which exceed a time window and but stiLL have unmatched regions are researched, the conditions of the ischemic penumbras and whether or not coLLateraL circuLation and deLayed perfusion exist and othersare fuLLy Learned about, in this way, an effective reperfusion treatment strategy is cLinicaLLy made through positive guiding, scientific bases are provided when a correct treatment scheme is made bya cLinicaL doctor, then effective treatment is reaLized, the reLapse rate and the disabiLity rate are decreased, treatment costs are Lowered, and remarkabLe sociaL benefits and economic benefits are reaLized.
