Timeline for Progression of T2WI and DWI Findings in Acute Stroke - In the acute phase T2WI will be normal, but in time the infarcted area will become hyperintense. - The hyperintensity on T2WI reaches its maximum between 7 and 30 days. After this it starts to fade. - DWI is already positive in the acute phase and then becomes more bright with a maximum at 7 days. - DWI in brain infarction will be positive for approximately for 3 weeks after onset (in spinal cord infarction DWI is only positive for one week!). - ADC will be of low signal intensity with a maximum at 24 hours and then will increase in signal intensity and finally becomes bright in the chronic stage. #Stroke #CVA #MRI #Interpretation #Progression #Timeline #Neurology #Radiology #Findings #Evolution
