[Multidetector computed tomography in the diagnosis of non-traumatic vascular emergencies].

Radiological imaging of the vascular system is an essential component in the clinical evaluation of vascular emergencies. Duplex ultrasound is still in use as a basic diagnostic means and enables initial diagnostic information. Digital subtraction angiography (DSA), the longtime gold standard, is now more often used with therapeutic interventions rather than purely diagnostic studies. However, over the past 10 years, there has been a rapid development of new technology that has deeply changed vascular imaging and allows a non-invasive depiction with a robust technique, greater speed and higher resolution. Advanced cross-sectional imaging techniques such as magnetic resonance imaging (MRI) and multidetector computed tomography (MDCT) angiography nowadays enable a dedicated diagnostic evaluation of acute aortic and peripheral arterial pathologies. Due to its enormous innovation and broad and quick availability angiographic multidetector computed tomography (MDCT) could replace catheter-based angiography in the diagnostic assessment. This article summarizes the performance of MDCT angiographic imaging and its diagnostic and therapeutic significance for the diagnostic assessment of non-traumatic aortic and peripheral arterial diseases.
