Abdominal pain is one of the most common reasons for patients to present to the emergency department (ED) in the USA, with an estimated seven million visits in 2007-2008, a figure which represents 8 % (±0.2 %) [2] of all ED visits and a 31.8 % increase from 1999-2000. Abdominal pain has a broad differential diagnosis that encompasses multiple organ systems and can provide a significant diagnostic challenge to the ED physician. Although magnetic resonance imaging (MRI) currently plays a limited role in the assessment of abdominal pain presenting to the ED in the nongravid population, its utility in the pregnant and pediatric population has already been proven. A proven diagnostic track record, lack of ionizing radiation and the ability to provide excellent tissue contrast without the use of nephrotoxic iodinated contrast, makes MRI an attractive imaging modality. As physicians and patients become more aware of the potential risks associated with exposure to ionizing radiation, ED MRI utilization is likely to increase. In this article, we discuss the MRI appearance of some of the most common diagnoses, which present as abdominal pain to the ED.
在美国，腹痛是患者前往急诊科（ED）就诊的最常见原因之一。据估计，2007 - 2008年有700万人次因腹痛就诊，这一数字占所有急诊科就诊人数的8%（±0.2%）[2]，与1999 - 2000年相比增长了31.8%。腹痛的鉴别诊断范围广泛，涉及多个器官系统，这给急诊科医生带来了重大的诊断挑战。尽管目前磁共振成像（MRI）在评估非妊娠人群因腹痛前往急诊科就诊时作用有限，但其在孕妇和儿童人群中的效用已得到证实。MRI具有经过验证的诊断记录、无电离辐射以及无需使用肾毒性碘化造影剂就能提供出色的组织对比度等优点，使其成为一种有吸引力的成像方式。随着医生和患者越来越意识到暴露于电离辐射的潜在风险，急诊科对MRI的使用可能会增加。在本文中，我们将讨论一些最常见的以腹痛形式呈现到急诊科的诊断疾病的MRI表现。
