TD and PD Tei indices should not be interchanged for fetal cardiac assessment; leaves open need for method-specific norms and validation.
Does the tissue Doppler method provide interchangeable Tei index measurements compared to the pulsed-wave Doppler method in fetuses?
Pulsed-wave Doppler and tissue Doppler methods yield poorly correlated Tei indices in fetuses and cannot be used interchangeably for assessing fetal cardiac function.
