The purpose of the present study was to evaluate the subjectively perceived patient comfort during magnetic resonance imaging (MRI) examinations and to assess potential differences between a recently introduced low field MRI scanner and a standard MRI scanner. Among other characteristics, the low field MRI scanner differs from the standard MRI scanner by offering more space (wider bore size of 80 centimeter diameter) and producing less noise, which may influence the patient comfort. In total, 177 patients were surveyed after MRI scans with either the low field MRI scanner (n = 91, MAGNETOM Free.Max, Siemens Healthineers) or the standard MRI scanner (n = 86, MAGNETOM Avanto Fit, Siemens Healthineers). Patients rated different aspects of comfort on a 5 point Likert scale: (a) claustrophobia, (b) comfort of the scanner table, (c) noise level and (d) vertigo during the scanning procedure. In terms of claustrophobia and comfort of the scanner table, patients rated both MRI scanners similar (e.g., mean ratings for claustrophobia: standard MRI scanner = 4.63 ± 1.04, low field MRI scanner = 4.65 ± 1.02). However, when asked for a comparison, patients did favor the more spacious low field MRI scanner. In terms of noise level, the low field MRI scanner was rated significantly better (mean ratings: standard MRI scanner = 3.72 ± 1.46 [median 4 = "rather not unpleasant"], low field MRI scanner = 4.26 ± 1.22 [median 5 = "not unpleasant at all"]). Patients did not perceive any significant difference in terms of vertigo between both MRI scanners. The newly developed low field MRI scanner offers constructional differences compared to standard MRI scanners that are perceived positively by patients. Worth highlighting is the significantly lower noise level and the innovative bore diameter of 80 centimeter, which offers more space to the patients.
本研究旨在评估磁共振成像（MRI）检查中患者的主观舒适度，并评估最近推出的低场 MRI 扫描仪与标准 MRI 扫描仪之间的潜在差异。除其他特点外，低场 MRI 扫描仪与标准 MRI 扫描仪的不同之处在于提供了更多的空间（更宽的孔径尺寸为 80 厘米），并且产生的噪音更小，这可能会影响患者的舒适度。共有 177 名患者在使用低场 MRI 扫描仪（n=91，MAGNETOM Free.Max，西门子医疗）或标准 MRI 扫描仪（n=86，MAGNETOM Avanto Fit，西门子医疗）进行 MRI 扫描后接受了调查。患者使用 5 分制 Likert 量表对舒适度的不同方面进行了评分：（a）幽闭恐惧症，（b）扫描仪台的舒适度，（c）扫描过程中的噪音水平和（d）眩晕。在幽闭恐惧症和扫描仪台舒适度方面，患者对两种 MRI 扫描仪的评分相似（例如，幽闭恐惧症的平均评分：标准 MRI 扫描仪=4.63±1.04，低场 MRI 扫描仪=4.65±1.02）。然而，当被要求进行比较时，患者确实更喜欢更宽敞的低场 MRI 扫描仪。在噪音水平方面，低场 MRI 扫描仪的评分明显更好（平均评分：标准 MRI 扫描仪=3.72±1.46[中位数 4=“相当不令人不愉快”]，低场 MRI 扫描仪=4.26±1.22[中位数 5=“完全不令人不愉快”]）。患者在两种 MRI 扫描仪之间的眩晕方面没有感觉到任何显著差异。新开发的低场 MRI 扫描仪与标准 MRI 扫描仪相比具有结构上的差异，这些差异被患者认为是积极的。值得强调的是，噪音水平显著降低，创新的 80 厘米孔径为患者提供了更多的空间。
