ABSTRACT

BACKGROUND: Autistic individuals encounter numerous barriers in accessing healthcare, including communication difficulties, sensory sensitivities, and a lack of appropriate adjustments. These issues are particularly acute during MRI scans, which involve confined spaces, loud noises, and the necessity to remain still. There remains no unified approach to preparing autistic individuals for MRI procedures. METHODS: A cross-sectional online survey was conducted with parents and carers of autistic individuals in the UK to explore their experiences, barriers, and recommendations concerning MRI scans. The survey collected demographic information and experiential accounts of previous MRI procedures. Quantitative data were analysed descriptively, while key themes were identified within the qualitative data through inductive thematic analysis. RESULTS: Sixteen parents/carers participated. The majority reported difficulties with communication, inadequate pre-scan preparation, and insufficient adjustments during MRI scans for their autistic children. Key barriers included an overwhelming sensory environment, radiographers' limited understanding of autism, and anxiety stemming from uncertainties about the procedure. Recommended improvements encompassed accessible communication, pre-visit familiarisation, noise-reduction and sensory adaptations, staff training on autism, and greater flexibility to meet individual needs. CONCLUSIONS: There is an urgent need to enhance MRI experiences for autistic individuals. This can be achieved through improved staff knowledge, effective communication strategies, thorough pre-scan preparation, and tailored reasonable adjustments. Co-producing clear MRI guidelines with the autism community could standardise sensitive practices. An individualised approach is crucial for reducing anxiety and facilitating participation. Empowering radiographers through autism-specific education and incorporating insights from autistic individuals and their families could transform MRI experiences and outcomes.

ABSTRACT

Background: Autistic individuals might undergo a magnetic resonance imaging (MRI) examination for clinical concerns or research. Increased sensory stimulation, lack of appropriate environmental adjustments, or lack of streamlined communication in the MRI suite may pose challenges to autistic patients and render MRI scans inaccessible. This study aimed at (i) exploring the MRI scan experiences of autistic adults in the United Kingdom; (ii) identifying barriers and enablers toward successful and safe MRI examinations; (iii) assessing autistic individuals' satisfaction with MRI service; and (iv) informing future recommendations for practice improvement. Methods: We distributed an online survey to the autistic community on social media, using snowball sampling. Inclusion criteria were: being older than 16, have an autism diagnosis or self-diagnosis, self-reported capacity to consent, and having had an MRI scan in the United Kingdom. We used descriptive statistics for demographics, inferential statistics for group comparisons/correlations, and content analysis for qualitative data. Results: We received 112 responses. A total of 29.6% of the respondents reported not being sent any information before the scan. Most participants (68%) confirmed that radiographers provided detailed information on the day of the examination, but only 17.1% reported that radiographers offered some reasonable environmental adjustments. Only 23.2% of them confirmed they disclosed their autistic identity when booking MRI scanning. We found that quality of communication, physical environment, patient emotions, staff training, and confounding societal factors impacted their MRI experiences. Autistic individuals rated their overall MRI experience as neutral and reported high levels of claustrophobia (44.8%). Conclusion: This study highlighted a lack of effective communication and coordination of care, either between health care services or between patients and radiographers, and lack of reasonable adjustments as vital for more accessible and person-centered MRI scanning for autistic individuals. Enablers of successful scans included effective communication, adjusted MRI environment, scans tailored to individuals' needs/preferences, and well-trained staff.


Why is this an important issue?: Magnetic resonance imaging (MRI) is an examination that shows human anatomy and may explain the causes of symptoms. Autistic people may need MRI scans for various reasons, such as low back pain, headaches, accidents, or epilepsy. They have known sensitivities to sound, light, smell, or touch and increased anxiety, so the narrow, loud, isolating, unfamiliar MRI environment may be overwhelming to them. If MRI scans are, for these reasons, inaccessible, many autistic people will have to live with long-standing conditions, pain, or other symptoms, or have delayed treatment, with impact on their quality of life, and life expectancy. What was the purpose of this study?: We tried to understand how autistic people perceive MRI examinations, things that work, and the challenges they face. We also asked for their suggestions to improve practice and accessibility. What did we do?: We distributed an online questionnaire to autistic adults through social media. We analyzed the data using appropriate statistical and text analysis methods. What were the results of the study?: We received 112 responses. Autistic people rated their overall MRI experience as average. Nearly a third (29.6%) reported they were not sent any information before MRI, and only 17.1% reported that radiographers offered some reasonable environmental adjustments. Most participants (68%) reported that radiographers provided detailed information on the day of the scan. Only 23.2% of them disclosed their autistic identity when booking MRIs. We found that quality of communication, physical environment, patient emotions, staff training, stigma, and timely autism diagnosis impacted their MRI experiences. What do these findings add to what was already known?: Autistic people MRI scan experiences are at the heart of this project. Our project shows that MRI for common symptoms is often inaccessible by autistic people. We should improve the MRI environment, adjust communication format/content for them, and deliver person-centered care in MRI. Health care professionals should receive relevant training, to understand the challenges autistic people might face and better support them in MRI scanning. What are potential weaknesses in the study?: The pandemic has impacted participant recruitment; therefore, the results of this sample may not reflect the full impact on the wider autistic population or adequately represent the autistic community, due to small size and including only people who could consent.These results come from different centers, so there is a lot of variation in the use of MRI equipment. How will these findings help autistic adults now or in the future?: We outline the main challenges associated with MRI, so autistic adults and their families/carers understand more of what they could expect in future examinations; hopefully, researchers and scanner manufacturers will try to tackle these challenges to make MRI scans truly accessible for autistic people.We shared this knowledge with stakeholders to develop guidelines and started using it in training. We want to ensure that MRI is person-centered and more accessible for autistic patients.

ABSTRACT

Magnetic Resonance Imaging (MRI) produces images with high soft tissue contrast without the use of ionising radiation, making it a valuable tool for scanning paediatrics. However, it can be difficult to scan children when they are awake, resulting often in poor image quality scans and necessitating the use of sedation and general anaesthesia (GA). The aim of sedation and anaesthesia is to reduce anxiety and movement during image acquisition, thereby improving compliance and image quality. However, there are adverse risks and costs to their use, leading to the need to consider alternative imaging adaptation methods. This research discussed potential methods of reducing anxiety and improving paediatric compliance during MRI examinations, by assessing their feasibility for use in the clinical setting. The literature suggests that adaption strategies and modification of radiographer techniques were mostly effective in reducing the requirement of sedation/GA.

ABSTRACT

PURPOSE: Lumbosacral lipoma (LSL) is a severe occult spinal dysraphism, frequently associated with neurological, urological and orthopaedic complications. Whole spine imaging is typically performed to identify concomitant, but spatially separate, congenital anomalies. Our hypothesis: the incidence of additional, clinically significant abnormalities of the neuraxis is low; thus, imaging should be optimised at the lumbosacral region. We aim to assess the prevalence and relevance of LSL-associated lesions. METHOD: A single-centre, retrospective, radiological review using a prospectively maintained operative database. INCLUSION CRITERIA: children (< 16 years) with confirmed diagnosis of LSL and received whole spine MRI. Fatty filum, syndromic cases and cutaneous stigmata above lesion level were excluded. Data was extracted from radiological imaging, reports and clinical correspondence. RESULTS: One hundred twelve patients (40:72, M:F) aged 0.5 years (0.2-2.7) (median ± IQR) with LSL had whole spine MRI between 2001 and 2017. Classification of LSL: transitional 48 (43%); dorsal 30 (27%); caudal 28 (25%) and chaotic 6 (5%). Additional anomalies included syringohydromyelia 44 (39%), subcutaneous tract 19 (17%), abnormal vertebral segmentation 18 (16%), dermoid cyst 1 and 1 Chiari I deformity. There were no Chiari II malformations. No child required surgery for an associated lesion. Binary logistic regression revealed no factors associated with predicting secondary lesions. CONCLUSIONS: In congenital LSL, additional anomalies of the neuraxis are typically loco-regional rather than pan-CNS and additional lesions are rarely clinically significant. The loco-regional distribution of anomalies suggests that only lumbosacral spinal imaging is required in the initial evaluation of LSL. Such a policy would lessen the anaesthetic/sedation time for children and reduce imaging cost per patient. MRI protocols could be refined to optimise imaging quality at the region of interest.

ABSTRACT

Nephrogenic systemic fibrosis (NSF) is a relatively new entity, first described in 1997. Few cases have been reported, but the disease has high morbidity and mortality. To date it has been seen exclusively in patients with renal dysfunction. There is an emerging link with intravenous injection of gadolinium contrast agents, which has been suggested as a main triggering factor, with a lag time of days to weeks. Risk factors include the severity of renal impairment, major surgery, vascular events and other proinflammatory conditions. There is no reason to believe that children have an altered risk compared to the adult population. It is important that the paediatric radiologist acknowledges emerging information on NSF but at the same time considers the risk:benefit ratio prior to embarking on alternative investigations, as children with chronic kidney disease require high-quality diagnostic imaging.

ABSTRACT

OBJECT: Spiral computed tomography (SCT) and, more recently, multislice SCT (MSCT) angiography have established roles in studying subarachnoid hemorrhage (SAH). Potential advantages in MSCT angiography include rapid acquisition, ready availability, ease of monitoring, high spatial resolution, some temporal resolution, and relative freedom from artifacts. The authors assert that these attributes make MSCT angiography the initial imaging method of choice in the assessment of not just SAH but all intracranial vascular pathophysiologies, particularly in children. METHODS: The installation of a MSCT unit sparked the authors' interest in using MSCT angiography and MSCT venography in cases in which they would have formerly performed magnetic resonance (MR) angiography, MR venography, or catheter angiography as an initial investigational method. They retrospectively evaluated seven cases in which they had used the former imaging techniques to study intracranial vascular pathophysiologies. All scans were obtained on a Siemens Sensation 16-slice scanner, and postprocessing was performed on a Leonardo Workstation. RESULTS: Multislice spiral CT consistently provided useful vascular imaging of a wide variety of intracranial vascular pathophysiologies and an alternative imaging modality in patients considered to be too unstable for more time-consuming investigations. CONCLUSIONS: Multislice spiral CT offers advantages over MR imaging in the assessment of intracranial vascular pathophysiologies and frequently allows complete avoidance or deferral of catheter angiography.
