"Another non-invasive technique is CTA, which utilises intravenous contrast medium injection to opacify the arterial lumen and detect any change in the calibre. Assessment of the stenosis, occlusion and collateral circulation can be done using multislice thin axial cuts followed by multiplanar reconstruction. Maximum intensity projections (MIP) and volume rendering techniques (VRT) can also be used in the assessment of the vessels."
"Digital subtraction angiography is an invasive technique done percutaneously through femoral catheter insertion. It is the gold standard for assessment of stenosis, occlusion and collateral flow and can be diagnostic and therapeutic."
