Scanning techniques
1. Use a 5-7 MHz probe (depending on the
patients sizeif severely obese, may need to use
a curvilinear probe) 2. A patient is supine with
a leg bent slightly and turned out 3. Beginning
in the groin at the CFV (before the Greater Saph.
Junction), scan in transverse compressing the
veins (walls of veins will collapse if no clot)
all the way down the leg, following the vessels
