Aortic dissection is an acute and life-threatening pathology, early diagnosis and precise evaluation allow a correct treatment. Computed tomography diagnoses dissection, demonstrates the two aortic channels separated by the intimal flap and shows its place and extension. Aortic aneurysms are permanent and localized dilation of all wall components. They are usually asymptomatic until complications appear. Radiologic studies are essential for diagnosis and treatment. Ultrasound is the suitable technic for diagnoses and follow-up in uncomplicated patients. CT is an excellent method to evaluate aortic aneurysms and their complications before and after surgery. Angiography is useful to determine visceral branches involvement and to identify anatomic variations. Magnetic Resonance is a new option. Probably it will be the choice in the future.
主动脉夹层是一种急性且危及生命的病症，早期诊断和精确评估有助于进行正确治疗。计算机断层扫描可诊断夹层，显示由内膜瓣分隔的两个主动脉腔，并展示其位置和范围。主动脉瘤是主动脉各层壁成分的永久性局限性扩张。在并发症出现之前，它们通常没有症状。影像学检查对诊断和治疗至关重要。超声是诊断和随访无并发症患者的合适技术。CT是评估主动脉瘤及其手术前后并发症的极佳方法。血管造影有助于确定内脏分支受累情况并识别解剖变异。磁共振成像（MRI）是一种新的选择。或许它将成为未来的首选。
