Expected headings
"Radiographic features"
"for mapping, evaluate the iliac arteries, common femoral arteries, the proximal, mid, and distal femoral arteries, popliteal artery, and the tibial and peroneal artery runoffs"
"There is a special category for an index 1.3-1.4 or above. These vessels are considered "non-compressible", and this is either because the arteries are very healthy or because there is heavy arteriolosclerotic or atherosclerotic calcification in the artery, preventing compression. The ultrasound waveform of the artery helps differentiate between these possibilities."
