[Diagnostic imaging in vascular diagnosis].

Previously, vascular imaging was done exclusively using angiography (X-ray projectional imaging of vessels opacified by iodinated contrast media). Recently angiography especially is used in combination with angioplasty (percutaneous enlargement of a closed or stenotic vessel). There has been a change from invasive to non invasive procedures. New developments in computed tomography (CT), magnetic resonance imaging (MR) and ultrasound have reduced the indications for the invasive digital subtraction angiography (DSA). Further improvement especially im MR-angiography and colour-coded dopplersonography will cover all primary diagnostic vascular examinations.
