Vector Flow Imaging Compared with Digital Subtraction Angiography for Stenosis Assessment in the Superficial Femoral Artery – A Study of Vector Concentration, Velocity Ratio and Stenosis Degree Percentage

Hansen KL et al.

| Fig. 1 Vector velocity images of 2 patients with stenosis of the SFA are shown in a and b, where A corresponds to lesion no. 3 and B to lesion no. 1(Table 1). Both frames are taken from systole. The lesions are marked with an asterisk, and in each frame, the ROI for calculation of the vector concentration is illustrated with a white box. Direction and velocity of the blood flow estimated with TO are shown by the color map.
