超低场便携式MRI在神经重症与卒中单元的临床实施
该回顾性研究分析了92例神经重症及卒中单元患者共95次超低场（0.064 T）便携式MRI扫描，其中25%为插管患者。插管患者扫描完成率100%，非插管患者87.3%（p=0.063），两组图像质量充足率分别为87.5%和87.3%（p=0.582），未观察到操作相关并发症。结论认为超低场便携式MRI可作为危重患者床旁影像安全检查选项。
要点
- 插管危重患者行超低场便携式MRI扫描完成率达100%，未发生操作相关并发症。
- 超低场便携式MRI图像质量充足率在插管与非插管患者中均约87%。
- 该技术适合需要持续监测的神经重症患者的床旁影像评估。
局限性
- 单中心回顾性分析，样本量有限（92例患者、95次扫描）。
- 图像质量评估采用五点Likert量表，未报告与标准MRI的对比。

PURPOSE: MRI diagnostics for patients with neurological pathologies and advanced monitoring or intensive care therapy are crucial to guide therapy. We aimed to examine the safety of ultra-low-field (ULF; 0.064 T) portable magnetic resonance imaging (pMRI) for stroke-unit and neuro-intensive care patients.
METHODS: This was a retrospective analysis of a tertiary hospital with neuro-intensive care and stroke-unit between May and August 2025. 92 patients received 95 scans for different pathologies: ischemic stroke (78%), hemorrhagic stroke (15%), meningoencephalitis/encephalitis (2%) and other conditions (5%). A total of 24 scans (25%) were performed on intubated patients (Study Group 1, n = 24 scans). This group was compared to scans performed on not intubated but surveilled patients (Study Group 2, n = 71 scans) in a univariate analysis assessing the completion of ULF-pMRI scans. Image quality was assessed by two trained neuroradiologists using the five-point Likert scale.
RESULTS: ULF-pMRI scans were successfully completed in all intubated patients (100%) and in 87.3% of not intubated patients (p = 0.063), with sufficient image quality in 87.5% and 87.3%, respectively (p = 0.582). No procedure-related complications were observed.
CONCLUSION: ULF-pMRI appears to be a safe bedside imaging option that can be integrated into routine clinical care in critically ill patients in neuro-intensive care who require prolonged surveillance.
