A Comparison of Regional Myocardial Velocity Information Derived by Pulsed and Color Doppler Techniques: An In Vitro and In Vivo Study
Why the study?
Can pulsed wave and color Doppler myocardial imaging be used interchangeably for regional myocardial velocity assessment?
Population
In vitro tissue-mimicking phantom and 25 normal human subjects examined at rest
Comparison
Pulsed wave Doppler myocardial imaging (PWDMI) vs Color Doppler myocardial imaging (CDMI)
Design
Cross-sectional

Implication
Caution against interchanging PWDMI and CDMI for peak velocities in practice; leaves open standardization for myocardial imaging research.
Structured PICO

Population
In vitro tissue-mimicking phantom and 25 normal human subjects examined at rest
I
Intervention
Pulsed wave Doppler myocardial imaging (PWDMI)
C
Comparator
Color Doppler myocardial imaging (CDMI)
O
Outcome
Agreement and correlation of regional myocardial contraction and relaxation velocitiessurrogate
Pulsed wave and color Doppler myocardial imaging cannot be used interchangeably for comparing peak velocities, though they can be used interchangeably for velocity profile recording and timing of events.
