blue painful leg iliofemoral DVT

Question 20

acute thrombus

Answer 20

dilated

noncompressible

low level echoes

poorly attached

spongy

homogeneous

smooth edges

flow around

Question 21

contricted

compressible

bright echoes

well adherent

rigid

heterogeneous

rough edges

flow through

aids in defining thrombus

absence of color does not mean thrombosis

presence of color does not exclude thrombosis
