From: Evaluation of superficial femoral artery-lesions after percutaneous transluminal angioplasty: color-coded summation images vs. monochromatic digital subtraction angiography

Fig. 1

Monochromatic digital subtraction angiography (DSA) with corresponding color-coded DSA image of a patient before and after percutaneous transluminal angioplasty (PTA). a Initial angiography demonstrates high grade stenosis of the distal superficial femoral artery (SFA). b The corresponding color-coded image shows reduced blood flow due to stenotic lesion, expressed by a color change of intraluminal contrast from bright green to dark blue. c, d Improved vessel diameter after PTA is demonstrated by enhanced blood flow, expressed by homogenous green color. All three readers concluded that no stenting was necessary for both the DSA series and the colored image
