Vessel does ____ collapse with light pressure by transducer on skin
____ high-velocity Doppler signal
____ of vessel walls is present
Imaging Characteristics of Normal Veins: _____: Flow is present without augmentation maneuvers.
______: _____ signals should be present in jugular, subclavian, innominate, and SVC because of retrograde transmission of right atrial pressure.

Is usually performed before lower extremity arterial bypass or coronary bypass operations
Veins 2-2.5 mm
Vein Mapping: ____ mapping of location of veins is important when surgeons plan an in situ bypass graft of lower extremity or when harvesting vein.
Preoperative vein mapping ____ exposing inadequate veins, which in turn decreases operative time and the possibility of wound complications from unnecessary incisions.
Presence and location

Assessment of Pulmonary Embolus: Majority originate from _____ extremity
Using venous duplex imaging to clarify indeterminate lung scan may help confirm clinical suspicion.
