“…MRI scanning was performed on 3T Discovery MR750 (GE Healthcare, Milwaukee, WI) with 32-channel head coil, without sedation. In addition to standard paediatric MRI preparation, younger participants were shown an animation to prepare them for MRI (Szeszak et al., 2016; McGlashan et al., 2018). The multiparametric MRI scan protocol included 3D fast spoiled gradient echo T1-weighted structural MRI (1 mm isotropic resolution, TR = 8.15 ms, TE = 3.172 ms, TI = 900 ms, FOV = 256 × 256 × 156 mm); EPI-based axial diffusion-weighted imaging (participants were scanned with at least one of two sequences, a longer protocol for those tolerating the scan well: TR = 8000 ms, TE = 63 ms, b = 1000s/mm 2 , 32 separate non-orthogonal directions, 4 additional b = 0 s/mm 2 images acquired, 2 mm isotropic voxel size, whole brain coverage, number of slices = 66; or shorter protocol if not tolerating the scan well: TR = 8000 ms, TE = 83 ms, b = 1000s/mm 2 , 3 orthogonal directions, 0.9 mm × 0.9 mm × 4 mm voxel size, number of averages = 2, whole brain coverage, number of slices = 30); and in a subset of participants single voxel MR spectroscopy (Fig.…”

BACKGROUND AND PURPOSE: SWI hypointense cerebral lesions have been reported in adults with the inherited cerebellar neurodegenerative disorder ataxia telangiectasia. This study aims to establish the prevalence, age-dependency, and spatial distribution of these lesions in children and young people with ataxia telangiectasia. MATERIALS AND METHODS:Participants with classic ataxia telangiectasia and matched controls underwent SWI acquisition at 3T at 1 or 2 time points. SWI hypointense lesions were manually labeled according to the Microbleed Anatomical Rating Scale. Differences in prevalence of lesion number between groups with ataxia telangiectasia and without ataxia telangiectasia were tested with the Fisher exact test, and differences in age between participants with ataxia telangiectasia with and without lesions were tested using independent samples from the Mann-Whitney U test. The relationship between age and lesion number was modeled as an exponential function.RESULTS: Analyzable SWI datasets from 17 participants with ataxia telangiectasia (with median age at first scan of 12.4 years; range, 4.6-20.2 years; 8 [47%] were female) and 22 matched healthy controls showed prevalence of SWI hypointense lesions in 41% of participants with ataxia telangiectasia and 0% in controls (P ¼ .001, the Fisher exact test). Lesions were exclusively supratentorial and predominantly lobar. Participants with ataxia telangiectasia with SWI hypointense lesions were older than those without (median age was 15.2 years versus 9.3 years, U ¼ 10.5, P ¼ .014). An exponential curve described the relationship between age and lesion number (R 2 ¼ 0.67).CONCLUSIONS: SWI hypointense lesions are common in children and young people with ataxia telangiectasia, accumulating from 12 years of age onward. In contrast to cerebellar-dominant neurodegeneration in ataxia telangiectasia, SWI hypointense lesions were exclusively supratentorial. Further investigation is needed to establish the clinical relevance of these imaging-detected lesions.

“…In one study, through the effective use of multiple preparation resources, anesthesia rates were reduced from 47% to 27% [2]. A variety of methods have been reported to prepare children for MRI including the use of informational videos [3], mock scanners [4], play tunnels, vibrating mats with MRI scanner audio simulations [5], and the use of small scale models for demonstrating the MRI procedure to children [6]. Having a process to avoid anesthesia is also preferred among parents [7,8].…”

Background A magnetic resonance image (MRI) is a diagnostic test that requires patients to lie still for prolonged periods within a claustrophobic and noisy environment. This can be difficult for children to tolerate, and often general anesthetic (GA) is required at considerable cost and detriment to patient safety. Virtual reality (VR) is a newly emerging technology that can be implemented at low cost within a health care setting. It has been shown to reduce fear associated with a number of high-anxiety situations and medical procedures. Objective The goal of the research was to develop a VR resource to prepare pediatric patients for MRI, helping to reduce anxieties in children undergoing the procedure. Methods A freely accessible VR preparation resource was developed to prepare pediatric patients for their upcoming MRI. The resource consists of an app and supporting preparation book and used a series of panoramic 360 degree videos of the entire MRI journey, including footage from within the bore of the scanner. The app, deployed via the Android Play Store and iOS App Store, can be viewed on most mobile phones, allowing a child to experience an MRI in VR using an inexpensive Google Cardboard headset. The app contains 360 degree videos within an animated, interactive VR interface designed for 4 to 12-year-olds. The resource was evaluated as part of a clinical audit on 23 patients (aged 4 to 12 years), and feedback was obtained from 10 staff members. In 5 patients, the resource was evaluated as a tool to prepare patients for an awake MRI who otherwise were booked to have an MRI under GA. Results The VR preparation resource has been successfully implemented at 3 UK institutions. Of the 23 patients surveyed, on a scale of 1 to 10, the VR resource was rated with a median score of 8.5 for enjoyment, 8 for helpfulness, and 10 for ease of use. All patients agreed that it made them feel more positive about their MRI, and all suggested they would recommend the resource to other children. When considering their experiences using the resource with pediatric patients, on a scale of 1 to 10, the staff members rated the VR resource a median score of 8.5 for enjoyment, 9 for helpfulness, and 9 for ease of use. All staff believed it could help prepare children for an awake MRI, thus avoiding GA. A successful awake MRI was achieved in 4 of the 5 children for whom routine care would have resulted in an MRI under GA. Conclusions Our VR resource has the potential to relieve anxieties and better prepare patients for an awake MRI. The resource has potential to avoid GA through educating the child about the MRI process.
