A variety of magnetic resonance imaging (MRI)-compatible skin-marker localization devices are available on the market. MRI protocols call for the liberal use of the skin markers over the specific site of symptoms or over any palpable mass. This study investigates the usefulness of patient-assisted placement of 1 000-mg fish oil capsules as skin markers over the area of maximum localized pain, signs, or symptoms and correlates this placement with any potential underlying neuropathology or potential pain generator.
One-hundred symptomatic patients undergoing MRI were assessed for focal or localized signs or symptoms. Under the direction of a physician and with guidance from the patient, the MRI technician placed a 1 000-mg fish-oil capsule over the area of maximum pain or signs and symptoms. Patients with poorly localized, diffuse symptoms or an area of maximal signs and symptoms outside the field of view of the MRI were not included in this study. All MRI exams were reviewed by clinical physicians and radiologists or neuroimaging physicians.
In all 100 cases, the images show clearly visible MRI-compatible skin-surface markers that correlate with potential underlying neuropathology.
Our results show that 1 000-mg fish-oil capsules can be used as MRI localization devices as a cost-effective alternative to more expensive commercially available devices.
市场上有多种与磁共振成像（MRI）兼容的皮肤标记定位装置。MRI方案要求在症状的特定部位或任何可触及的肿块上大量使用皮肤标记。本研究调查了患者辅助在最大局部疼痛、体征或症状区域放置1000毫克鱼油胶囊作为皮肤标记的有用性，并将此放置与任何潜在的潜在神经病理学或潜在疼痛源相关联。
对100名有症状且正在接受MRI检查的患者进行局灶性或局部体征或症状评估。在医生的指导下并在患者的引导下，MRI技术人员将一粒1000毫克的鱼油胶囊放置在疼痛或体征和症状最严重的区域。症状定位不佳、症状弥漫或MRI视野外有最大体征和症状区域的患者未纳入本研究。所有MRI检查均由临床医生和放射科医生或神经影像医生进行复查。
在所有100例病例中，图像显示与潜在潜在神经病理学相关的清晰可见的与MRI兼容的皮肤表面标记。
我们的结果表明，1000毫克鱼油胶囊可作为MRI定位装置，作为比更昂贵的市售装置更具成本效益的替代品。
