Objectives: After studying the article entitled “Role of B-Color and Resolution Sonography Presets for the Diagnosis of Lower Extremity Deep Vein Thrombosis (DVT),” you will be able to:
Determine the risk factors for DVT
Evaluate the characteristics of enhanced resolution and B-color presets for imaging DVT
Assess the utility of using different imaging presets for the diagnosis of DVT
What is the most dangerous complication of an undetected DVT? Stroke Pulmonary embolism Skin rash Swelling
What does Virchow’s triad for venous thrombosis include? Age, height, and weight Swelling, redness, and pain Hypercoagulability, venous stasis, and endothelial injury Diabetes, hypertension, and obesity
What is the average sensitivity of detecting a lower extremity DVT with sonography? 48% 75% 95% 98%
How many deaths are attributed annually to DVT and pulmonary embolism? 10,000 to 20,000 75,000 to 100,000 100,000 to 150,000 100,000 to 180,000
Historically, what was the most common examination used to assess for DVT prior to sonographic evaluation? Venogram MRI Plain film radiography Nuclear medicine
What patient factor was found to be statistically significant for DVT in this study? BMI Presence of a prior DVT Height Presence of diabetes
What is a limitation of magnetic resonance imaging (MRI) in diagnosing DVT? Claustrophobia Radiation Thermal injury to tissue Electromagnetic effects
For the diagnosis of DVT, the results of this study showed that resolution and B-color presets, compared with the default imaging presets, Improved sensitivity Decreased sensitivity Had no effect on sensitivity Improved accuracy but not sensitivity
What does the B-color preset help amplify? Red blood cells Doppler signal Wall lumen Border definition
What patient group has a higher risk of recurrent DVT? Females Males Patients with heart disease Children
