Mean values and limits of Gaussian tolerance interval of cerebral blood flow (CBF) obtained with continuous spin arterial labeling MR imaging in 42 children with sickle cell anemia, classified as having low risk of stroke by transcranial Doppler ultrasonography criteria (mean blood flow velocity in main cerebral arteries <170 cm/s).

CBF	Whole brain	Right hemisphere	Left hemisphere	Difference (p value)
mean ± SD	83±19	82±20	84±19	0.119
Limits of tolerance interval	40 − 126	36 − 127	41 − 127	0.119

Data are: ml/100g/min; statistics: paired 2-sided t-test
