Cross-sectional imaging plays a crucial role in the triage of patients with acute abdominal pain. Ionizing radiation exposure is a recognized drawback of computed tomography (CT), the primary imaging technique. MR imaging is a promising alternative to CT; it provides excellent image quality with high-contrast resolution without the disadvantages of ionizing radiation and iodinated contrast. This article provides a basic overview of the typical MR findings of the most frequent disease entities encountered in the setting of the nontraumatic acute abdomen, including direct comparison with CT findings to familiarize the readers with these same findings on MR.
横断面成像在急性腹痛患者的分诊中起着关键作用。电离辐射暴露是计算机断层扫描（CT）这一主要成像技术公认的缺点。磁共振成像（MR）是CT的一种有前景的替代方法；它能提供具有高对比度分辨率的出色图像质量，且没有电离辐射和碘化造影剂的缺点。本文概述了非创伤性急腹症中最常见疾病实体的典型MR表现，包括与CT表现进行直接对比，以使读者熟悉MR上的这些相同表现。
