The case is reported of a 31-year-old man with a retained metallic intraocular foreign body (IOFB) in the left eye who underwent magnetic resonance imaging (MRI) for investigation of a subsequent unrelated brachial plexus injury Despite the patient providing good history of IOFB, the decision to proceed with MRI was based on screening orbit X-ray which was reported as normal. A review of published reports regarding screening recommendations for MRI for patients with IOFB is provided. A minimum recommendation is for prescreening questionnaire; belief of the patient history is critical. If there is any doubt after history and examination by an ophthalmologist, then computed tomography imaging of the orbits is recommended. Whether screening by plain X-ray imaging is worthwhile is debatable as the sensitivity and specificity of this modality is poor.
报告了一例31岁男性，其左眼有一枚残留的金属眼内异物（IOFB），因后续无关的臂丛神经损伤接受磁共振成像（MRI）检查。尽管患者提供了详细的IOFB病史，但进行MRI检查的决定是基于眼眶X线筛查，该检查报告为正常。本文提供了关于IOFB患者MRI筛查建议的已发表报告综述。最低建议是进行预筛查问卷；相信患者的病史至关重要。如果在眼科医生询问病史和检查后仍有任何疑问，则建议进行眼眶计算机断层扫描成像。普通X线成像筛查是否值得存在争议，因为这种检查方式的敏感性和特异性较差。
