The article by Boutin et al. [1] in this issue of the AJR documents a surprinsingly great variation in the MR screening procedures used at different academic centers throughout the United States. Although considerable literature now exists concerning the MR imaging of patients with ferromagnetic implants, devices, and foreign bodies [2-4], no uniform screening protocol to identify such patients has yet been adopted. The Safety Committee of the Society for Magnetic Resonance Imaging (SMRI) has recommended that "each imaging site should develop a standardized policy for screening patients with suspected metallic foreign bodies" [5]. To date, however, the SMRI has neither proposed nor endorsed a specific screening protocol for general use.
布廷等人发表在本期《美国放射学杂志》上的文章[1]记录了美国不同学术中心在磁共振成像筛查程序上令人惊讶的巨大差异。尽管目前已有大量关于有铁磁性植入物、装置和异物患者的磁共振成像的文献[2-4]，但尚未采用统一的筛查方案来识别这类患者。磁共振成像协会（SMRI）安全委员会建议“每个成像站点都应为疑似有金属异物的患者制定标准化的筛查政策”[5]。然而，迄今为止，SMRI既未提出也未认可普遍适用的具体筛查方案。
