p=.12). We also found no association between age and the number of completed scans (r=.02, p=.63).
Figure 3. Scan quantity and quality. A) Scan quantity: the percentage of children that completed the MR run (100%=512 participants). B) The number (and percentage) of scans with sufficient scan quality relatie to the quantity of the scans. C) Scan quality over time: the percentage of participants that were included on all scans in 30, 45 or 60 min, separately for boys and girls.
Scan quantity in relation to scanner related distress
Pearson’s correlations on the number of completed scans (ranging from 0-9, M=8.29, SD=2.08) showed a positive association between excitement towards the scan and the number of scans completed (before MRI simulation: r=.21, p<.001; before MRI scan: r=.30, p<.001; after MRI scan: r=.25, p<.001), and a negative association between tension towards the scan and the number of scans completed (before MRI simulation: r=-.18, p<.001; before MRI scan: r=-.16, p<.001; after MRI scan: r=-.17, p<.001), see Figure 4. All Pearson correlations were significant at Bonferroni corrected alpha level, adjusted for the number of distress estimates (six in total: excitement and tension before MRI simulation, before MRI scan, after MRI scan; α=0.5/6, Bonferroni corrected α=.008).
