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.
以前，血管成像完全依靠血管造影术（通过碘化造影剂使血管显影的X线投影成像）。近来，血管造影术尤其常与血管成形术（经皮扩张闭塞或狭窄的血管）联合使用。已经出现了从侵入性检查到非侵入性检查的转变。计算机断层扫描（CT）、磁共振成像（MR）和超声方面的新进展减少了侵入性数字减影血管造影（DSA）的应用指征。磁共振血管造影和彩色编码多普勒超声检查的进一步改进将涵盖所有主要的血管诊断性检查。
