A Neuroimaging Preparation Protocol Tailored for Autism.
Gradual exposure, social stories, incentives and play therapy let 31 autistic kids complete awake MRI 67–87 % of the time without sedation.
01Research in Context
What this study did
Tziraki et al. (2021) built a step-by-step package to help 31 autistic kids lie still for an MRI while awake. The team used social stories, practice sessions, prizes, and play therapy before the real scan.
What they found
Two-thirds to almost nine-tenths of the children finished each MRI sequence without sedation. The tailored habituation worked for most kids aged about 3–8.
How this fits with other research
Nordahl et al. (2016) got 100 % of their slightly older kids through the scanner using ABA shaping and reinforcement. The lower rate in Tziraki et al. (2021) looks like a drop, but their group was younger and had no prior practice visits.
Lory et al. (2023) also created a kid-friendly assessment, pairing heart-rate watches with functional analysis to sort repetitive behavior. Both papers show that small tech tweaks and behavioral steps make tough tests possible.
Pine et al. (2006) and Snyder et al. (2012) likewise trimmed assessment time for preschoolers, proving the field keeps finding faster, gentler ways to collect data.
Why it matters
If you need brain scans for your learners, copy the package: read a social story, run a toy scanner, hand out stickers, then book the real thing. You may skip sedation, save money, and keep families happy. Start with a five-minute mock scan next Monday and track how long each child stays still.

03Original abstract
This paper describes the key basic elements required for a successful multi-parametric MRI data acquisition in awake children with autism. The procedure was designed by taking into account methodological challenges arising from the acquisition of Resting State fMRI (RS fMRI) data, and factors such as cost, time, and staff availability. The ultimate aim was to prepare an imaging preparation protocol with high transferability to the whole autism spectrum, adaptable for use in a multi-site research with multiple time points. As part of a randomized pharmaco-intervention study, 31 children aged 4-10 years with Neurofibromatosis 1 and autism underwent MR imaging at baseline and end of intervention. The protocol consisted of tailored habituation instructions including gradual exposure to scanner noise, a social stories booklet, positive incentive strategies, and Play Therapy support. Success rate for initial acquisition was 71% for GABA+ MR spectroscopy at either location, 87% for perfusion, and 67% for diffusion assessment, and 71% for RS fMRI. Qualitative data indicated that 84% parents found the habituation protocol helpful. LAY SUMMARY: Here we describe a protocol for brain Magnetic Resonance Imaging (MRI) tailored for children with ASD to help reduce stress and avoid sedation during scanning. This procedure can make advanced medical imaging more accessible and promote a better MRI experience for families of children with ASD.
