Abstract
ADC values were calculated at the hips of normal children n = 19 and children with SCD who were either asymptomatic with no known previous hip disease n = 13 or presented for the first time with clinical symptoms of hip pathology n = 12 ADC values were compared for differences among groups with and without AVN using nonparametric statistical methodsThe ADC values were elevated in the hips of children with AVN median ADC = 157 × 10−3 mm2/s 95 confidence interval = 086–210 and differed significantly in pairwise comparisons all P 005 from normal children 074 046–098 asymptomatic children with SCD 055 025–085 and SCD children who had symptoms referable to their hips but did not show findings of hip AVN on conventional MRI or radiographs 046 018–072
