What is
approximate age of infarction in A and D image?
ANS—
A.-- ADC values seen to be low
within hours after the stroke and continue to decline for the next few days. They
remain reduced through the first 4 to 5 days after stroke and then undergo
pseudonormalization between 4 and 10 days . After this the ADC subsequently has
been found to rise in the lesion (i.e., the ADC map shows hyperintensity)
beyond 10 days So,approximate age of
infarction in A is less than 4—5 days while that of D is about more than ten
days.
