While computed tomography (CT) offers faster cross-sectional imaging in the emergency department, owing to its concerns for higher radiation exposure, magnetic resonance imaging (MRI) applications in acute settings are increasingly validated. A significant proportion of patients present to the emergency department with abdominopelvic symptoms, most commonly acute abdominal pain. Early detection with imaging and timely intervention can significantly decrease morbidity and mortality in conditions such as acute pancreatitis or ovarian torsion. MRI encompasses better soft-tissue resolution, nonusage of ionizing radiation and iodinated contrast media, nonoperator dependency, and higher reproducibility. This review discusses the MRI protocols and applications in abdominopelvic emergencies.
虽然计算机断层扫描（CT）在急诊科提供了更快的横断面成像，但由于其对更高辐射暴露的关注，磁共振成像（MRI）在急性情况下的应用越来越得到验证。相当一部分患者因腹部和盆腔症状就诊于急诊科，最常见的是急性腹痛。通过影像学早期检测和及时干预可以显著降低急性胰腺炎或卵巢扭转等疾病的发病率和死亡率。MRI 具有更好的软组织分辨率、不使用电离辐射和碘造影剂、不依赖操作人员以及更高的可重复性。本文讨论了 MRI 在腹部和盆腔急症中的协议和应用。
