Figure Lengend Snippet: Overview of MRI simulation training protocol. First, the examiner and participant reviewed two “social stories,” one about the upcoming MRI session, the other about the “mock scan” training. Second, the child listened to 30-s-long multimodal MRI sounds outside the MRI simulator. For the 2 and 4 min steps, the child played the target game inside the simulator during which children were instructed to keep a white dot (representing the position of their forehead indexed by the motion tracker) in the green center of the target. Between the two target game steps, a 2-min musical movie was played, stopping when head motion exceeded 1.5 mm. Two 6-minutes blocks of R-fMRI simulations followed.

Article Snippet: To this end, we used an MRI simulator, a Siemens-32-channel mock head coil with mirror to see a screen on the back of the bore used to project the visual stimuli, a head motion tracking system, and the corresponding software package, all acquired from Psychology Software Tools Inc.

Figure Lengend Snippet: Overview of MRI simulator training and MRI scan outcomes. A) Flowchart of participant outcomes. Of the 250 children enrolled in this study, 201 passing the MRI simulator training attempted the MRI multiscan session. B) Stacked bars show the number of MRI simulator training sessions needed for children passing the training protocol (blue) vs. those failing it (orange) among the N = 250. Most who passed the training (n = 150) did so in one session. Of the remaining, n = 41 passed training after two training sessions, n = 20 after three, n = 8 after four, and n = 2 after five sessions. Among those who failed the training protocol, n = 15 children failed after one, n = 7 after two, n = 3 after three, n = 3 after four, and n = 1 after five sessions. C). The stacked bars show the percentage of children who completed each scan with passing or failing Q/A (blue and orange, respectively), the gray stacks represented the percentage of children who did not complete a given scan along the session. As detailed in the , for the task fMRI runs, 23 (11%) children were unable to complete the practice tasks outside the scanner and, thus, were not administered the task fMRI. Information for seven children regarding task practice was not available and they were counted among those not completed.
