How to Use DEFINITY®: System Optimization
Because every patient poses unique imaging challenges...
Optimize your DEFINITY® contrast images1,2
Leading societies advocate ultrasound contrast when image quality is suboptimal1,3:
American Society of Echocardiography (ASE) Consensus Statement1:
"Despite optimization of transducer frequency, sector width, and focus position, image quality can stay suboptimal in these patients unless [an ultrasound] contrast agent is used."
The Intersocietal Accreditation Commission for Echocardiography Laboratories (IAC) states...3
Poor endocardial border definition is defined as the inability to detect 2 or more contiguous segments in any 3 of the apical views
Contrast should be used in the presence of poor endocardial border definition to quantify chamber dimensions and volumes, and to assess regional wall motion
Because every patient poses unique imaging challenges, it is important to adjust the controls on your ultrasound system to achieve optimal contrast imaging quality1,2
Ultrasound system contrast presets serve as a good starting point4
Proper dosing and administration techniques play an important role in producing quality contrast images5
Key system controls used to achieve optimal results with DEFINITY®5:
Optimizing your DEFINTY® contrast images...
Increases the percentage of evaluable segments5-7
Improves endocardial border delineation7,8
Allows for a more accurate diagnosis5-7
