“…Patients at the MR-Linac are not only immobilized, but also need to tolerate placement of receiver coils while positioned in the bore for a longer time [22]. It is known that patients can experience claustrophobia and anxiety in an MR scanner [23,24], and the rate usually increases with longer and narrower bore openings [23,25]. Due to the split-magnet design [14], the MRIdian Linac has a tunnel length of about 232 cm, which is longer than at contemporary diagnostic MR scanners and could potentially contribute to anxiety [25].…”

“…Due to the split-magnet design [14], the MRIdian Linac has a tunnel length of about 232 cm, which is longer than at contemporary diagnostic MR scanners and could potentially contribute to anxiety [25]. While the absolute numbers of diagnostic MR scans terminated early due to claustrophobia or anxiety are generally small, in the range of 1-2% [24], early termination of fractions in radiation therapy for this reason needs to be prevented as effectively as possible.…”

Purpose Magnetic resonance-guided radiotherapy (MRgRT) has recently been introduced in our institution. As MRgRT requires high patient compliance compared to conventional techniques and can be associated with prolonged treatment times, feasibility and patient tolerance were prospectively assessed using patient-reported outcome questionnaires (PRO-Q). Materials and methods Forty-three patients were enrolled in a prospective observational study and treated with MRgRT on a low-field hybrid Magnetic Resonance Linear Accelerator system (MR-Linac) between April 2018 and April 2019. For assistance in gated breath-hold delivery using cine-MRI, a video feedback system was installed. PRO-Qs consisted of questions on MR-related complaints and also assessed aspects of active patient participation. Results The most commonly treated anatomic sites were nodal metastases and liver lesions. The mean treatment time was 34 min with a mean beam-on time of 2:17 min. Gated stereotactic body radiotherapy (SBRT) was applied in 47% of all patients. Overall, patients scored MRgRT as positive or at least tolerable in the PRO-Q. Almost two thirds of patients (65%) complained about at least one item of the PRO-Q (score ≥4), mainly concerning coldness, paresthesia, and uncomfortable positioning. All patients reported high levels of satisfaction with their active role using the video feedback system in breath-hold delivery. Conclusion MRgRT was successfully implemented in our clinic and well tolerated by all patients, despite MR-related complaints and complaints about uncomfortable immobilization. Prospective clinical studies are in development for further evaluation of MRgRT and for quantification of the benefit of MR-guided on-table adaptive radiotherapy.

“…Risk of bias of eligible studies was assessed using a customized checklist (Table 2) of 9 questions based on the systematic review by Sanderson et al [40] and “The Joanna Briggs Institute Reviewers’ Manual 2014” [41]. One point was given for a positive answer to each of the 9 questions, and each study was categorized as low, medium or high risk of bias.…”

Purpose: The aim of this study was to examine the prevalence and incidence of retinal vein occlusions (RVO) in Europe. Methods: A systematic review and meta-analysis of the prevalence and incidence of RVO in Europe according to the Meta-Analyses of Observational Studies in Epidemiology (MOOSE) guidelines was performed in the databases PubMed, Embase and Web of Science. Based on Eurostat data, the total number of affected individuals in the EU was calculated and projected to the year 2050. Results: The random-effects pooled prevalence of RVO in Europe was 0.7% (95% CI: 0.5–0.9%) in persons aged 55 years and older based on the examination of 25,002 individuals from 4 prevalence studies. No European incidence studies were identified. The total number of affected individuals in the EU was estimated to rise by almost 20% from 900,000 today to 1.1 million in 2050. Conclusion: Published articles on the prevalence and incidence of RVO in Europe are limited. With the expected increase in affected persons, further epidemiological research is warranted for adequate healthcare planning.

“…This causes significant economic burden. 4 Many associated factors may contribute to MRI associated claustrophobia. For instance, during the procedure, MRI machine produces radiofrequency pulses, which make large sounds within the machine.…”

Background: Claustrophobia associated with MRI scan is a well-recognized problem all over the world. The unpleasant psychological experience during MRI can lead to premature cancellation of the study resulting in non-interpretable data. In addition, performing future studies on the claustrophobic patient may not be possible leading to non-utilization of an important diagnostic modality. This study was conducted with the aim to determine a cheap and short intervention which can be applicable to small radiology set up as well.Methods: A prospective study was conducted at a tertiary care hospital from October 2016 to December 2016. Accompanying someone was the first strategy used to coped MR imaging claustrophobia followed by placebo (multivitamin), listening Quran and closed eye (blindfold). All those patients who failed to respond in these strategies were finally labeled as an unsuccessful candidate. Listening of Quran was selected as one of the tools as all the patients were Muslims in present study.Results: Among 84 claustrophobic patients, a closed eye was the most successful strategy found effective in (13) 81.2%, followed by placebo 66.7% patients, listening Quran (7) 30.4%, accompanying someone (15) 17.85% while 4% patients remained claustrophobic after application of all strategies. Significant association of accompanying someone and placebo was observed with education (p-value 0.037) and age of the patients (0.016) respectively.Conclusions: In general, placebo, being accompanied by someone and blindfold were found to be the most effective strategies to cope with MRI related claustrophobia. However, the success of these strategies is also dependent on certain factors like age, education status and socioeconomic status of the patients.
