This study compared the CBF measurements using single and multiple delay ASL on 28 children without neurological or cerebrovascular disorders. Results showed that CBF of multiple delay ASL was significantly higher than the values of single delay ASL by a mean of 18%. CBF of both ASL techniques increased with age.
