Monochromatic and color-coded DSA images before and after PTA with stent implantation. a Selective angiography of the right renal artery shows ostial stenosis. b Corresponding color-coded image reveals a slight color-inhomogeneity within the proximal renal artery, indicating relevant flow-limitation. c After PTA and stent implantation monochromatic DSA does not reveal any residual stenosis. d Corresponding parametric DSA shows homogenous color-coding within the renal artery after stenting and a warmer color-gradient, indicating improved blood flow
