Figure 6.

Ultrasound images of medial vascular calcifications. Shown are typical B-mode (A) and colour-mode (B) ultrasound images of a superficial femoral artery. B-mode images show the typical ‘string-of-beads’ pattern of media calcifications (arrows) with intact endothelial interface in both longitudinal sector and cross section (insert) images (courtesy C Garn). On colour-mode ultrasound image, the dense pattern of media calcifications (arrows), smooth endothelial interface, and homogeneous blood flow pattern (red colour) is shown.
