Diffusion weighted imaging (DWI) is a magnetic resonance imaging (MRI) non-contrast sequence that can indicate tissue ischemia or infarction. Adrenal infarct may present similarly to biliary or gallbladder pathologies, and the differential diagnosis during emergency work-up can be narrowed utilizing DWI sequences. In this paper, we describe the usefulness of DWI for urgent diagnosis in a case of non-hemorrhagic adrenal infarct of a pregnant female presenting with right upper quadrant pain. Although uncommon, adrenal infarct may occur in patients with hypercoagulability and localizing pain that is unexplained by other imaging modalities. We outline the imaging features of DWI in evaluating adrenal infarct as a safe and time effective application for patients with contraindications to imaging with ionizing radiation.

弥散加权成像（DWI）是一种磁共振成像（MRI）非对比序列，可显示组织缺血或梗死。肾上腺梗死的表现可能与胆道或胆囊病变相似，在急诊检查期间利用DWI序列可缩小鉴别诊断范围。在本文中，我们描述了DWI在一名因右上腹疼痛就诊的妊娠女性非出血性肾上腺梗死病例的紧急诊断中的作用。肾上腺梗死虽然不常见，但可能发生在具有高凝性且有定位疼痛但其他影像学检查无法解释的患者中。我们概述了DWI在评估肾上腺梗死时的成像特征，这是一种对有电离辐射成像禁忌证的患者安全且高效的应用。
