Abstract:
Objective To investigate the variation law of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values in patients with cerebral infarction, and to explore the relationship between the changes and the prognosis of cerebral infarct patients. Methods Sixteen patients with cerebral infarction were recruited and divided into 2 groups:good recovery and poor rehabilitation. ADC and FA values were calculated in infarct areas and control areas which were the regions with symmetrical position and the same area as infarct areas. The difference of ADC and FA values in patients at acute and earlier chronic stage between the two areas were analyzed. Results ①At acute stage, ADC values in infarct areas were lower than those in control areas (P<0.05). At early chronic stage, there was no significant difference of ADC values between infarct areas and control areas (P>0.05), moreover ADC values were higher than that at acute phase (P<0.05). ②FA values in infarct areas were lower than those in control areas at both acute and early chronic stage (P<0.05). At early chronic stage, FA values were lower than those at acute stage (P<0.05). ③There was no significant difference of ADC and FA values at both acute and early chronic stage between good recovery group compared with poor rehabilitation group (P>0.05). Conclusion There are certainly rules in changes of ADC and FA values in patients with cerebral infarction at acute and earlier chronic stage.
