Magnetic resonance imaging (MRI) has revolutionized our capacity to examine brain alterations in traumatic brain injury (TBI). However, little is known about the level of implementation of MRI techniques in clinical practice in TBI and associated obstacles.
A diverse set of health professionals completed 19 multiple choice and free text survey questions.
Of the 81 respondents, 73.4% reported that they acquire/order MRI scans in TBI patients, and 66% indicated they would prefer MRI be more often used with this cohort. The greatest impediment for MRI usage was scanner availability (57.1%). Less than half of respondents (42.1%) indicated that they perform advanced MRI analysis. Factors such as dedicated experts within the team (44.4%) and user-friendly MRI analysis tools (40.7%), were listed as potentially helpful to implement advanced MRI analyses in clinical practice.
Results suggest a wide variability in the purpose, timing, and composition of the scanning protocol of clinical MRI after TBI. Three recommendations are described to broaden implementation of MRI in clinical practice in TBI: 1) development of a standardized multimodal MRI protocol; 2) future directions for the use of advanced MRI analyses; 3) use of low-field MRI to overcome technical/practical issues with high-field MRI.
磁共振成像（MRI）彻底改变了我们检查创伤性脑损伤（TBI）患者脑部病变的能力。然而，对于MRI技术在TBI临床实践中的应用水平及相关障碍，我们知之甚少。
一组不同的医疗专业人员完成了19道多项选择题和自由文本调查问卷。
在81名受访者中，73.4%报告他们会为TBI患者进行MRI扫描或开具MRI检查医嘱，66%表示他们希望在这一患者群体中更频繁地使用MRI。MRI使用的最大障碍是扫描仪的可用性（57.1%）。不到一半的受访者（42.1%）表示他们会进行高级MRI分析。团队中有专门的专家（44.4%）和用户友好的MRI分析工具（40.7%）等因素被列为在临床实践中实施高级MRI分析可能有帮助的因素。
结果表明，TBI后临床MRI扫描方案的目的、时机和组成存在很大差异。本文描述了三项建议，以扩大MRI在TBI临床实践中的应用：1）制定标准化的多模态MRI方案；2）高级MRI分析的未来应用方向；3）使用低场MRI来克服高场MRI的技术/实际问题。
