Aortic aneurysm rupture, aortic dissection, PAU, acute aortic occlusion, traumatic aortic injury, and aortic fistula represent acute abdominal aortic conditions. Because of its speed and proximity to the emergency department, helical CT is the imaging test of choice for these conditions. MR imaging also plays an important role in the imaging of aortic dissection and PAU, particularly when the patient is unable to receive intravenous contrast material. In this era of MDCT, conventional angiography is used as a secondary diagnostic tool to clarify equivocal findings on cross-sectional imaging. Ultrasound is helpful when CT is not readily available and the patient is unable or too unstable to undergo MR imaging.
主动脉瘤破裂、主动脉夹层、穿透性主动脉溃疡、急性主动脉闭塞、创伤性主动脉损伤和主动脉瘘均为急性腹主动脉疾病。由于螺旋CT速度快且距离急诊科近，因此是这些疾病的首选影像学检查。磁共振成像在主动脉夹层和穿透性主动脉溃疡的成像中也发挥着重要作用，尤其是当患者无法接受静脉造影剂时。在多层螺旋CT时代，传统血管造影用作辅助诊断工具，以明确横断面成像上的模糊发现。当无法立即进行CT检查且患者无法或病情过于不稳定而无法接受磁共振成像时，超声检查会有所帮助。
