Fig. 2

Pre- and post-PTA parametric colour-coded DSA with region of interests (ROI) of the same AVF shown in Fig. 6. DSA sequences were post-processed and parametric colour-coded DSA was generated. ROIs were chosen pre- and post-stenosis. The differences of TTP (dTTP) values between these 2 ROIs pre- and post-PTA were generated. (a) Pre-PTA dTTP was 1 s. (b) Post-PTA dTTP was 0, indicating contrast flow was faster after intervention
