Background Magnetic resonance imaging (MRI) is an important noninvasive diagnostic tool used in multiple facets of medicine, especially in the assessment of the neurological system with increasing usage over the past decades. Advancement in technology has led to the creation of portable MRI (pMRI) that was cleared for use recently. Methodology A prospectively collected retrospective study was conducted at a single institution to include patients aged >18 years, admitted to the hospital, and requiring MRI for any brain pathology. pMRI was completed using portable MRI. Traditional MRI was completed with a standard 1.5T MRI, and when possible, the results of the two studies were compared. Results We obtained pMRI on 20 patients, with a total of 22 scans completed. Notably, on the pMRI, we were able to identify midline structures to determine midline shifts, identify the size of ventricles, and see large pathologies, including ischemic and hemorrhagic strokes, edema, and tumors. Patients with implants or electrodes in and around the calvarium sometimes pose challenges to image acquisition. Conclusions Portable brain MRI is a practical and useful technology that can provide immediate information about the head, especially in an acute care setting. Portable brain MRI has a lower resolution and quality of imaging compared to that of transitional MRI, and therefore, it is not a replacement for traditional MRI.
背景 磁共振成像(MRI)是医学多个领域中使用的一种重要的非侵入性诊断工具,尤其是在评估神经系统方面,在过去几十年中其使用频率不断增加。技术的进步导致了便携式MRI(pMRI)的出现,该设备最近已获批使用。
方法 在一家机构进行了一项前瞻性收集的回顾性研究,纳入年龄大于18岁、住院且因任何脑部病变需要进行MRI检查的患者。使用便携式MRI完成pMRI检查。使用标准1.5T MRI完成传统MRI检查,并尽可能比较两项研究的结果。
结果 我们对20例患者进行了pMRI检查,共完成22次扫描。值得注意的是,在pMRI上,我们能够识别中线结构以确定中线移位、识别脑室大小,并观察到较大的病变,包括缺血性和出血性中风、水肿和肿瘤。颅骨内及周围有植入物或电极的患者有时会给图像采集带来挑战。
结论 便携式脑部MRI是一种实用的技术,能够提供有关头部的即时信息,尤其是在急性护理环境中。与传统MRI相比,便携式脑部MRI的分辨率和成像质量较低,因此,它不能替代传统MRI。
