“…Furthermore, the technicians were instructed to support the patients as in clinical routine avoiding being overly protective to reflect clinical reality. Last, it should be mentioned that there are now MR scanners with a slightly shorter (1.25 m) and wider bore (0.7 m; Siemens Magnetom Espree) available [55].…”

Reduction of Claustrophobia with Short-Bore versus Open Magnetic Resonance Imaging: A Randomized Controlled Trial

et al. 2011

BackgroundClaustrophobia is a common problem precluding MR imaging. The purpose of the present study was to assess whether a short-bore or an open magnetic resonance (MR) scanner is superior in alleviating claustrophobia.MethodsInstitutional review board approval and patient informed consent were obtained to compare short-bore versus open MR. From June 2008 to August 2009, 174 patients (139 women; mean age = 53.1 [SD 12.8]) with an overall mean score of 2.4 (SD 0.7, range 0 to 4) on the Claustrophobia Questionnaire (CLQ) and a clinical indication for imaging, were randomly assigned to receive evaluation by open or by short-bore MR. The primary outcomes were incomplete MR examinations due to a claustrophobic event. Follow-up was conducted 7 months after MR imaging. The primary analysis was performed according to the intention-to-treat strategy.ResultsWith 33 claustrophobic events in the short-bore group (39% [95% confidence interval [CI] 28% to 50%) versus 23 in the open scanner group (26% [95% CI 18% to 37%]; P = 0.08) the difference was not significant. Patients with an event were in the examination room for 3.8 min (SD 4.4) in the short-bore and for 8.5 min (SD 7) in the open group (P = 0.004). This was due to an earlier occurrence of events in the short-bore group. The CLQ suffocation subscale was significantly associated with the occurrence of claustrophobic events (P = 0.003). New findings that explained symptoms were found in 69% of MR examinations and led to changes in medical treatment in 47% and surgery in 10% of patients. After 7 months, perceived claustrophobia increased in 32% of patients with events versus in only 11% of patients without events (P = 0.004).ConclusionsEven recent MR cannot prevent claustrophobia suggesting that further developments to create a more patient-centered MR scanner environment are needed.Trial RegistrationClinicalTrials.gov NCT00715806

“…Im Gegensatz zu grçßeren Kindern, wo insbesondere MRT-Systeme in offener Bauweise zu einer Minderung der Sedierungsrate beitragen [14], lassen sich Neugeborene, Säuglinge und Kleinkinder nicht im Wachzustand untersuchen. Einige Arbeitsgruppen favorisieren eine Sedierung von Kleinkindern bis zum 5.…”

Currently, a paradigm shift towards expanded early use of cranial MRI in newborns at risk and infants in the first year of life can be observed in neonatology. Beyond clinical MRI applications, there is progressive use of functional MRI (fMRI) in this age group. On the one hand, fMRI allows monitoring of functional developmental processes depending on maturational stage; on the other hand, this technique may provide the basis for early detection of pathophysiological processes as a prerequisite for functionally guided therapeutic interventions. This article provides a comprehensive review of current fMRI applications in neonates and infants during the first year of life and focuses on the associated methodological issues (e. g. signal physiology, sedation, safety aspects).

BackgroundPatients often mention distress, anxiety, or claustrophobia related to MRI, resulting in no‐shows, disturbances of the workflow, and lasting psychological effects. Patients' experience varies and is moderated by socio‐demographic aspects alongside the clinical condition. While qualitative studies help understand individuals' experiences, to date a systematic review and aggregation of MRI individuals' experience is lacking.PurposeTo investigate how adult patients experience MRI, and the characterizing factors.Study TypeSystematic review with meta‐aggregation and meta‐synthesis.Population220 patients' reported experience of adults undergoing clinical MRI and 144 quotes from eight qualitative studies.AssessmentSystematic search in PubMed, Scopus, Web of Science, and PsycInfo databases according to the PRISMA guidelines. For quality appraisal, the Joanna Briggs Institute (JBI) tools were used. Convergent segregated approach was undertaken.Data AnalysisParticipant recruitment, setting of exploration, type of interview, and analysis extracted through Joana Briggs Qualitative Assessment and Review Instrument (JBI QARI) tool. Meta‐synthesis was supported by a concept map. For meta‐aggregation, direct patient quotes were extracted, findings grouped, themes and characterizing factors at each stage abstracted, and categories coded in two cycles. Frequency of statements was quantified. Interviews' raw data unavailability impeded computer‐aided analysis.ResultsEight articles out of 12,755 initial studies, 220 patients, were included. Meta‐aggregation of 144 patient quotes answered: (1) experiences before, at the scanning table, during, and after an MRI, (2) differences based on clinical condition, and (3) characterizing factors, including coping strategies, look‐and‐feel of medical technology, interaction with professionals, and information. Seven publications lack participants' health literacy level, occupation, and eight studies lack developmental conditions, ethnicity, or country of origin. Six studies were conducted in university hospitals.Data ConclusionAggregation of patients' quotes provide a foundational description of adult patients' MRI experience across the stages of an MRI process. Insufficient raw data of individual quotes and limited socio‐demographic diversity may constrain the understanding of individual experience and characterizing factors.Level of Evidence1Technical EfficacyStage 5

Untersuchungstoleranz von Kindern und Adoleszenten in einem 1,5 Tesla MR-Tomografen mit offenem Magnetdesign

Abstract: Pediatric MR imaging using a 1.5 Tesla MR scanner with an open design can be conducted in children and adolescents with excellent acceptance. The failure rate of 3.0 % of cases for pediatric MR imaging is comparable to that of a conventional low-field open MR scanner.
