Why the study?
Do gated SPECT, echocardiography, and cardiac magnetic resonance imaging provide interchangeable measurements of left ventricular ejection fraction and volumes?
Do gated SPECT, echocardiography, and cardiac magnetic resonance imaging provide interchangeable measurements of left ventricular ejection fraction and volumes?
LVEF measurements from gated SPECT, echocardiography, and cardiac MRI can be used interchangeably in clinical practice, but caution is required when comparing left ventricular volume measurements across these modalities.
May support LVEF interchangeability in practice; leaves open volume standardization for research.
This study showed good overall correlations between LVEF, EDV and ESV values derived from GSPECT, ECHO and CMRI. LVEF obtained from any of these three imaging modalities could be used interchangeably. However, care should be taken in comparing LV volumes.
