Arterial spin-labeling mri with 1800 msec postlabeling delay

Arterial spin-labeling mri with 1800 msec postlabeling delay improves agreement with [15O]water PET in humans.

“Correlations with [15O]water PET were strongest for 1800 msec single-PLD and generally decreased with longer PLDs”

Arterial spin-labeling mri with 1800 msec postlabeling delay improves cerebral blood flow test-retest reliability in humans (ICC > 0.75).

“The 4-week test-retest reliability was highest for single-PLD ASL using 1800 msec (ICC > 0.75)”
