The review emphasizes information relevant for everyday radiological practice and highlights recent advances that can be readily applied in the clinical routine.Results/Conclusion Computed tomography pulmonary angiography (CTPA) is the current reference standard for the diagnosis of acute PE. Ventilation and perfusion (VQ) scanning or – in centers with adequate expertise – magnetic resonance imaging (MRI) is indicated in pregnant or young patients and patients with contraindications to iodinated contrast. Invasive angiography is reserved for patients with intended endovascular treatment. Artifacts, acute non-thrombotic PE, chronic PE and non-embolic pulmonary artery diseases should always be considered as differential diagnoses.Key points: Citation Format PB - © Georg Thieme Verlag KG DO - 10.1055/a-0900-4200 UR - http://www.thieme-connect.com/products/ejournals/abstract/10.1055/a-0900-4200 ER -
