Why the study?
Is annular M-mode displacement as sensitive as tissue Doppler imaging for assessing cardiac function in fetuses with intrauterine growth restriction?
Is annular M-mode displacement as sensitive as tissue Doppler imaging for assessing cardiac function in fetuses with intrauterine growth restriction?
M-mode imaging offers a simpler alternative to tissue Doppler imaging that may be equally sensitive for detecting subtle cardiac dysfunction in IUGR fetuses.
M-mode may simplify fetal cardiac assessment in IUGR; leaves open prospective validation of equivalence to TDI.
Both M-mode and TDI demonstrate annular motion changes and consequently cardiac dysfunction in IUGR fetuses. M-mode imaging is simpler to perform and could be as sensitive as TDI for detecting subtle changes.
