Advanced Cardiovascular Assessment & Quantification
Specialized Cardiovascular Analysis Tools
Achieve higher resolution, visualize blood flow in Color Doppler and investigate myocardial abnormalities with advanced VevoStrain Software analysis tools. The Vevo 2100 system offers new imaging features, including Color Doppler Mode, strain analysis and ECG gating, which were previously unavailable on the Vevo 770 system.
Color Doppler Mode
Identification of vessel flow patterns in real-time
Deep vessel visualization
Faster imaging, less inter-operator variability
Sensitive screening tool for:
- Valvular Disease Models
- Pulmonary Hypertension
- Hypertrophy
- Diastolic Dysfunction
- Drug-Induced Vascular Injury
Examples: Cardiac Hypertrophy
 |
| High velocity and chaotic, turbulent flow characterize the mouse hypertrophic heart (right; 3800 mm/s) as compared to the normal mouse heart on the left (velocity = 800 mm/s) |
Drug Induced Vascular Injury
 |
Color Doppler Mode, a new feature of the Vevo 2100 system, is used as a guide to find the Superior Mesenteric Artery.
In this example, hemodynamic changes are shown to occur in the mesenteric vasculature of rats as a result of DIVI (Drug Induced Vascular Injury) |
VevoStrain Analysis
Quantitative evaluation of myocardial abnormalities in vivo to detect wall abnormalities
Speckle tracking to assess circumferential, radial and longitudinal axes of heart motion
Calculation of velocity, displacement, strain and strain rate parameters Exportable data
