Duplex/Color Flow Imaging Quiz

Which of the following is a capability of Duplex/Color Flow Imaging?

• Identify venous thrombosis (acute/chronic)

• Detect arterial blockages

• Measure blood pressure

• Diagnose diabetes

What is one of the limitations of Duplex/Color Flow Imaging?

• It cannot detect soft tissue masses

• Visualization may be sub-optimal secondary to edema, scarring, obesity

• It cannot identify venous thrombosis

• It is not affected by obesity

Which of the following is NOT a capability of Duplex/Color Flow Imaging?

• Detect venous incompetence

• Detect soft tissue masses

• Non-occluding partial thrombus

• Diagnose bone fractures

How can the limitations of Duplex/Color Flow Imaging due to obesity be mitigated?

• Using a higher frequency probe

• Using a lower frequency probe

• Increasing the imaging time

• Using a different imaging technique

What is the recommended patient position for examining peripheral veins in the lower extremity?

• Supine with arm in "pledge position"

• Reversed Trendelenberg position

• Prone with legs elevated

• Sitting with legs crossed

For reflux examination in the lower extremity, how should the patient be positioned?

• Lying flat on the back

• Standing up, bearing weight on the contralateral leg

• Sitting with legs crossed

• Supine with arm in "pledge position"

What is the recommended patient position for examining peripheral veins in the upper extremity?

• Reversed Trendelenberg position

• Standing up, bearing weight on the contralateral leg

• Supine with arm in "pledge position"

• Sitting with legs crossed

What does the compression of the veins in a transverse (trv) view suggest?

• There is deep vein thrombosis

• There is no deep vein thrombosis

• There is a proximal occlusion

• There is a distal occlusion

What does the lack of respiratory variation suggest during a venous ultrasound?

• A more distal occlusion

• A more proximal occlusion

• No deep vein thrombosis

• Partial color filling

What does the lack of augmentation suggest during a venous ultrasound?

• A more distal occlusion to flow

• A more proximal occlusion

• No deep vein thrombosis

• Complete color filling
